A Simple Guide to Pixels, Size and Quality"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">What is image resolution? In everyday use, image resolution describes the amount of picture information in a digital image, especially its width and height in pixels. Resolution influences how much detail an image can show, how large it can be printed and whether it looks sharp at its displayed size.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The term is often confused with file size, physical print size, PPI and DPI. These measurements are related, but they are not interchangeable. A clear distinction helps when preparing a passport photo, uploading an application, designing a website, printing a document or reducing a photograph for email.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Quick answer:<\/strong>&nbsp;Check pixel dimensions first. An image measuring 1920 \u00d7 1080 pixels contains 1,920 columns and 1,080 rows of pixels. PPI connects those pixels to a physical print size, while DPI describes printer output. File size in KB or MB depends on more than resolution.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">What Is a Pixel?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A pixel is one small picture element in a raster image. Each pixel stores colour and brightness information. Thousands or millions of pixels arranged in rows and columns create the photograph, screenshot or scanned page that you see.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At a normal viewing size, individual pixels blend together. Enlarging the image far enough makes the square grid more noticeable. This blocky appearance is commonly called pixelation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pixels do not have one fixed physical size. The same digital image can appear small on one screen, large on another or be printed at several sizes. Its pixel count stays unchanged unless software resamples it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Image Dimensions and Total Pixels<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pixel dimensions state an image\u2019s width and height. Common examples include 600 \u00d7 600 px, 1280 \u00d7 720 px, 1920 \u00d7 1080 px and 4000 \u00d7 3000 px.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Multiply width by height to estimate the total number of pixels:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>1920 \u00d7 1080 = 2,073,600 pixels<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is about 2.07 megapixels. A 4000 \u00d7 3000 image contains 12,000,000 pixels, or 12 megapixels. More pixels provide more potential detail and more freedom to crop or print large, but they do not guarantee a good photograph. Focus, lighting, lens quality, noise, processing and compression also matter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pixel dimensions should always be read in context. A 600 \u00d7 600 headshot may be exactly right for an application portal but too small for a large poster. A 6000 \u00d7 4000 camera photograph may be useful for editing and printing but unnecessarily heavy for a thumbnail. Resolution is therefore not a simple score in which the largest number always wins.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Image Resolution?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Image resolution can mean different things in different contexts. Websites and upload forms usually refer to pixel dimensions, while printing requirements may specify pixel density at a chosen physical size. Phone and monitor specifications may instead describe the display\u2019s pixel count or density.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ask what measurement a requirement actually uses:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pixels:<\/strong>\u00a0the digital width and height, such as 1200 \u00d7 800 px.<\/li>\n\n\n\n<li><strong>Megapixels:<\/strong>\u00a0the approximate total pixel count.<\/li>\n\n\n\n<li><strong>PPI:<\/strong>\u00a0how many image pixels are assigned to each printed or displayed inch.<\/li>\n\n\n\n<li><strong>DPI:<\/strong>\u00a0how densely a printer places physical dots.<\/li>\n\n\n\n<li><strong>KB or MB:<\/strong>\u00a0the amount of storage used by the encoded file.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A form asking for \u201c600 \u00d7 600 pixels\u201d is specifying dimensions. A printer asking for \u201c300 PPI at 4 \u00d7 6 inches\u201d is specifying pixel density and physical size together. A website limiting a file to \u201c2 MB\u201d is specifying storage size.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Resolution and Sharpness Are Different<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When asking what is image resolution, remember that resolution describes how much pixel information is available, not whether that information is clear. Motion blur, missed focus, camera shake, noise and heavy compression can make a high-resolution file look poor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Perceived sharpness also changes with viewing conditions. A small image can look crisp on a phone yet reveal softness when printed large. A large file can look sharp when reduced because several source pixels contribute to each displayed pixel. Viewing distance, screen density, contrast and sharpening all influence the result.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Compare images at the same displayed or printed size. Judging one file at 100% zoom and another fitted to the screen can create a misleading impression of their quality.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PPI and DPI Are Not the Same<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">PPI: pixels per inch<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">PPI connects a digital pixel count to a physical size. If a 3000-pixel-wide photograph prints 10 inches wide, the effective resolution is 300 PPI:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>3000 pixels \u00f7 10 inches = 300 PPI<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Print the same file 20 inches wide and the effective resolution becomes 150 PPI. No pixels disappeared; the same pixels were spread across a larger area.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">DPI: dots per inch<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">DPI is mainly a printer specification. A printer can use several ink or toner dots to reproduce the colour and tone represented by one image pixel. Therefore, a printer rated at 1200 DPI does not require a 1200-PPI photograph.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People often say \u201c300 DPI image\u201d when they mean a 300-PPI image prepared for printing. The distinction matters when calculating required pixel dimensions or discussing printer hardware.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Does 72 PPI Matter on the Web?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A stored PPI value does not determine how many pixels an ordinary web image contains. Browsers primarily lay out raster images according to their intrinsic pixel dimensions, CSS size and the device\u2019s pixel density.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, two 1200 \u00d7 800 files can contain different PPI metadata yet still have the same pixel dimensions. If a website displays both at the same CSS size, changing only the metadata from 72 PPI to 300 PPI normally does not create extra detail or make the file sharper.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For web use, concentrate on suitable pixel dimensions, responsive delivery, format and compression. Google\u2019s guidance on image performance explains that browsers can choose among different image widths according to the display size and device pixel ratio.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Image Resolution for Printing?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Printing gives pixels a physical size. To estimate the pixels required for a print, multiply each dimension in inches by the target PPI:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>print width in inches \u00d7 PPI = required pixel width<\/code><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><code>print height in inches \u00d7 PPI = required pixel height<\/code><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Print size<\/th><th>Pixels at 300 PPI<\/th><th>Pixels at 200 PPI<\/th><\/tr><\/thead><tbody><tr><td>4 \u00d7 6 inches<\/td><td>1200 \u00d7 1800<\/td><td>800 \u00d7 1200<\/td><\/tr><tr><td>5 \u00d7 7 inches<\/td><td>1500 \u00d7 2100<\/td><td>1000 \u00d7 1400<\/td><\/tr><tr><td>8 \u00d7 10 inches<\/td><td>2400 \u00d7 3000<\/td><td>1600 \u00d7 2000<\/td><\/tr><tr><td>A4, approximately 8.27 \u00d7 11.69 inches<\/td><td>Approximately 2480 \u00d7 3508<\/td><td>Approximately 1654 \u00d7 2338<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/helpx.adobe.com\/si\/photoshop\/desktop\/crop-resize-transform\/resize-adjust-resolution\/resolution-specs-for-printing-images.html\" data-type=\"link\" data-id=\"https:\/\/helpx.adobe.com\/si\/photoshop\/desktop\/crop-resize-transform\/resize-adjust-resolution\/resolution-specs-for-printing-images.html\">Adobe describes 300 PPI<\/a> as a common standard for high-quality prints viewed closely. Lower effective resolution may still work for a poster or large display viewed from farther away. The correct choice depends on the printer, paper, image, viewing distance and quality expected, so ask the print provider when the result is important.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To answer what is image resolution for a specific print, start with the final physical dimensions. A 2400-pixel-wide file can print 8 inches wide at 300 PPI, 12 inches wide at 200 PPI or 16 inches wide at 150 PPI. Increasing the print size lowers the effective PPI unless the software adds pixels through resampling.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Resolution Is Not File Size<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Resolution measures pixels or pixel density; file size measures stored data. Two images with identical 2000 \u00d7 1500 dimensions can have very different file sizes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Storage size depends on factors including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>file format;<\/li>\n\n\n\n<li>compression method and quality setting;<\/li>\n\n\n\n<li>colour depth and transparency;<\/li>\n\n\n\n<li>image detail, texture and noise;<\/li>\n\n\n\n<li>metadata;<\/li>\n\n\n\n<li>animation or multiple frames; and<\/li>\n\n\n\n<li>the total pixel count.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A smooth illustration may compress efficiently, while a photograph containing hair, leaves, grain and fine texture may require more data at the same dimensions. Learn more about storage units in&nbsp;<a href=\"https:\/\/soakjam.com\/knowledge\/kb-vs-mb-vs-gb-a-simple-guide-to-file-size\/\">KB vs MB vs GB: A Simple Guide to File Size<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Resizing, Resampling and Scaling<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">These words are sometimes used loosely, but they describe different changes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Scaling for display<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A browser or document can display an image at a different visual size without changing the stored file. A 1200-pixel-wide image displayed at 600 CSS pixels still contains its original pixels; the software scales the appearance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Resampling<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Resampling changes the file\u2019s pixel dimensions. Downsampling from 4000 \u00d7 3000 to 1200 \u00d7 900 removes pixels. Upsampling to larger dimensions creates new pixels by estimating values from neighbouring pixels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Different resampling algorithms produce different balances of sharpness, smoothness and artefacts. Adobe and ImageMagick both document multiple methods because no single method is best for every image.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Changing print size without resampling<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Editing only the PPI or physical print-size setting can leave the pixel grid unchanged. A 3000 \u00d7 2400 image can be described as 10 \u00d7 8 inches at 300 PPI or 20 \u00d7 16 inches at 150 PPI. The file has the same pixels; only their intended physical density changes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can You Increase a Small Image\u2019s Resolution?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Software can enlarge a small image, but ordinary upsampling cannot recover detail that the original never recorded. It creates additional pixels by interpolation. The result may look smoother than a visibly blocky enlargement, yet fine text, faces or textures can remain soft or artificial.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AI enlargement tools may estimate plausible edges and textures. Those details are generated predictions, not guaranteed recovery of the original scene. This distinction is important for evidence, identity documents, medical images or any situation in which factual accuracy matters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whenever possible, return to the original camera file, scan again at a suitable setting or obtain a higher-resolution source. Avoid repeatedly saving and enlarging compressed copies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Aspect Ratio and Cropping<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aspect ratio is the relationship between width and height. A 4000 \u00d7 3000 image has a 4:3 ratio, while 1920 \u00d7 1080 is 16:9. Resizing with the aspect ratio locked prevents stretching.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If a form requires a square 600 \u00d7 600 image, changing a rectangular photograph directly to those dimensions can distort faces and objects. Crop it to a square first, then resize. Because this step removes pixels outside the selected area, begin with enough resolution for the final result.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A major crop can reduce total resolution quickly. For example, trimming a 4000 \u00d7 3000 image to the central 2000 \u00d7 1500 area keeps the same aspect ratio but leaves only one quarter of the original pixels. Check the remaining dimensions before ordering a print or exporting the final file.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Resolution Should You Use?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There is no universal best resolution. Choose it from the final use rather than selecting the largest file available.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Use<\/th><th>What to check first<\/th><th>Practical approach<\/th><\/tr><\/thead><tbody><tr><td>Website<\/td><td>Displayed width and device density<\/td><td>Serve appropriately sized responsive versions instead of one oversized file<\/td><\/tr><tr><td>Online form<\/td><td>Required width, height, format and maximum KB\/MB<\/td><td>Meet every stated limit; dimensions and file size are separate<\/td><\/tr><tr><td>Email or messaging<\/td><td>Readable detail and attachment limit<\/td><td>Keep the original, then send a smaller copy if needed<\/td><\/tr><tr><td>Photo print<\/td><td>Physical size and target PPI<\/td><td>Calculate pixels from print dimensions and confirm with the printer<\/td><\/tr><tr><td>Large poster<\/td><td>Viewing distance and print provider<\/td><td>Lower PPI may be acceptable because it is viewed farther away<\/td><\/tr><tr><td>Archive or future editing<\/td><td>Maximum trustworthy source detail<\/td><td>Preserve the highest-quality original separately<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Image Resolution for Websites?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Uploading a 5000-pixel-wide photograph for a small article card wastes bandwidth if visitors never need that size. It can slow loading, consume mobile data and increase storage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Responsive-image techniques allow a browser to select a suitable source for the layout and device. The HTML&nbsp;<code>srcset<\/code>&nbsp;and&nbsp;<code>sizes<\/code>&nbsp;attributes can offer several widths, while width and height attributes help reserve the correct space. Google and MDN provide detailed implementation guidance for site owners.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a website, the practical answer to what is image resolution begins with the rendered width. An image displayed at 700 CSS pixels may need a larger source on a high-density screen, but it still does not need the full dimensions of every modern camera photograph.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not reduce dimensions so aggressively that an image becomes blurry on high-density screens. Test the actual layout on desktop and mobile, and keep an untouched original outside the website workflow.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Meeting Online Upload Requirements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Read the complete instruction before editing. A portal may require all of these at once:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>an exact or maximum pixel width and height;<\/li>\n\n\n\n<li>a particular aspect ratio;<\/li>\n\n\n\n<li>JPG, PNG or another accepted format;<\/li>\n\n\n\n<li>a maximum file size; and<\/li>\n\n\n\n<li>a clear, uncropped subject.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Changing only the PPI metadata will not satisfy a pixel-dimension limit. Reducing dimensions may lower file size, but detailed photographs can still exceed a strict KB limit and need additional compression. Conversely, heavy compression can meet the limit while making text or facial details unreadable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use the&nbsp;<a href=\"https:\/\/soakjam.com\/image-compressor.html?mode=resize\">SOAKJAM Image Compressor &amp; Resizer<\/a>&nbsp;to resize or compress a copy in your browser. Check the output dimensions and file size before uploading, and keep the original file unchanged.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Check an Image\u2019s Resolution<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Windows<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Right-click the image, choose Properties and open the Details tab. Look for Dimensions, Width and Height. Menu wording can vary by Windows version and file type.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">macOS<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Select the file in Finder and choose Get Info, or open it in Preview and use the Inspector. Look for pixel dimensions rather than relying only on a DPI value.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Android and iPhone<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Open the image in the Photos or Gallery application and look for Info, Details or an information icon. Some applications show dimensions and file size; others show only selected metadata.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the device does not reveal the required information, open a copy in a trusted editor. Avoid uploading private identity images to an unknown checking website.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Resolution Mistakes<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Assuming that changing 72 PPI to 300 PPI automatically adds detail.<\/li>\n\n\n\n<li>Stretching width and height independently and distorting the image.<\/li>\n\n\n\n<li>Confusing a 2 MB limit with a pixel-dimension requirement.<\/li>\n\n\n\n<li>Upscaling a thumbnail and expecting it to match the original photograph.<\/li>\n\n\n\n<li>Uploading a huge camera file for a small website display.<\/li>\n\n\n\n<li>Compressing repeatedly until text and edges develop visible artefacts.<\/li>\n\n\n\n<li>Discarding the original after creating a smaller copy.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Format also affects quality, transparency and compression. The guide&nbsp;<a href=\"https:\/\/soakjam.com\/knowledge\/pdf-vs-jpg-vs-png-which-file-format-should-you-use\/\">PDF vs JPG vs PNG<\/a>&nbsp;explains when each format is appropriate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Is a 1920 \u00d7 1080 image high resolution?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It contains about 2.07 million pixels and can be suitable for many screen uses. Whether it is \u201chigh resolution\u201d depends on its displayed or printed size, the source quality and the required result.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is 300 PPI always necessary for printing?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. It is a common target for close-viewed, high-quality prints, but larger prints viewed from a distance may work at lower effective PPI. Ask the print provider for important work.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does changing DPI reduce file size?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Changing only a metadata value may leave both pixel dimensions and encoded image data almost unchanged. File size drops substantially when you reduce pixel dimensions, change format, remove unnecessary data or apply stronger compression.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why does my image look blurry after uploading?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The source may be too small for the displayed size, the website may enlarge or recompress it, or the image may have been cropped or saved repeatedly. Compare the uploaded result with the original pixel dimensions and the page\u2019s actual display size.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the difference between resolution and quality?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Resolution describes pixel quantity or density. Quality is broader and also includes focus, lighting, noise, colour, dynamic range, compression and editing. A large image can still be poor quality.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Should I resize or compress an image first?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Set the required dimensions first, then choose a suitable format and compression level. Resizing pixels that will never be used usually provides the largest efficient reduction. Review the result at its intended size before submitting it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">What is image resolution? It is best understood by separating pixel dimensions, pixel density, print size and storage size. Pixels determine the digital grid, PPI connects that grid to physical size, DPI describes printer dots, and KB or MB measures the encoded file.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Start with the final requirement. Preserve the original, keep the aspect ratio correct, calculate print needs when necessary and resize or compress only a copy. This approach produces clearer images without carrying unnecessary data or pretending that software can restore detail that was never captured.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Learn how image resolution, pixel dimensions, PPI and DPI affect screens, printing and file size\u2014and how to resize images without common mistakes.<\/p>\n","protected":false},"author":1,"featured_media":16,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[90],"tags":[136,134,135],"class_list":["post-12","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-computing-technology","tag-digital-images","tag-image-editing","tag-image-resolution"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>What Is Image Resolution?
