We verified the size figures against Google\u2019s own WebP documentation and the current browser-support state against caniuse, then walked the real converter UI so the steps below match what you\u2019ll actually click.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Quick answer:<\/strong> Convert PNG to WebP to ship <strong>smaller web images that look identical<\/strong>. Use <strong>lossless WebP<\/strong> to keep perfect quality \u2014 Google measures these at about <strong>26% smaller than the original PNG<\/strong>, transparency included. Use <strong>lossy WebP<\/strong> when you can accept imperceptible loss for a much bigger size cut. WebP plays in every modern browser (global support ~96%), so it\u2019s safe for web delivery \u2014 but it\u2019s a <em>web<\/em> format: keep PNG for editing masters and printing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Jump to a section<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"#what\">What WebP is (and why it\u2019s smaller)<\/a><\/li><li><a href=\"#numbers\">How much smaller: the real numbers<\/a><\/li><li><a href=\"#lossless-lossy\">Lossless vs lossy WebP \u2014 which to pick<\/a><\/li><li><a href=\"#support\">Browser support: is WebP safe to ship?<\/a><\/li><li><a href=\"#keep-png\">When to keep PNG instead<\/a><\/li><li><a href=\"#tool\">Convert PNG to WebP on xconvert<\/a><\/li><li><a href=\"#faq\">FAQ<\/a><\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what\">What WebP is (and why it\u2019s smaller)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>WebP<\/strong> is an image format developed by <strong>Google<\/strong> specifically to make web images smaller without an obvious quality drop. Its key trick is that one format covers two compression modes:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Lossless<\/strong> \u2014 reconstructs every pixel exactly, like PNG, but with a more efficient encoder. Nothing is thrown away.<\/li><li><strong>Lossy<\/strong> \u2014 discards visual detail the eye is unlikely to notice (like JPEG), trading a little fidelity for a much smaller file.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Crucially, <strong>WebP supports transparency (the alpha channel) in <em>both<\/em> modes<\/strong> \u2014 so a transparent PNG logo stays transparent after conversion, whether you go lossless or lossy. That\u2019s the property that lets WebP replace transparent PNGs on the web, which JPEG never could.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So converting a PNG to WebP isn\u2019t changing what the image <em>is<\/em> \u2014 it\u2019s re-encoding the same picture with a smarter algorithm built for the web. A <code>.png<\/code> and the resulting <code>.webp<\/code> look the same on screen; the <code>.webp<\/code> just weighs less.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"numbers\">How much smaller: the real numbers<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Google publishes its own measurements, and these are the figures to trust:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Conversion<\/th><th>Size change (per Google)<\/th><\/tr><\/thead><tbody><tr><td>PNG \u2192 <strong>lossless<\/strong> WebP<\/td><td><strong>~26% smaller<\/strong> than the PNG<\/td><\/tr><tr><td>Adding transparency to lossless WebP<\/td><td>costs only <strong>~22% extra bytes<\/strong><\/td><\/tr><tr><td>Lossy WebP with transparency<\/td><td>typically <strong>~3\u00d7 smaller<\/strong> than the equivalent PNG<\/td><\/tr><tr><td>JPEG \u2192 lossy WebP (for reference)<\/td><td><strong>25\u201334% smaller<\/strong> at equal quality<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Read those together and the practical takeaway is clear: even the <em>no-quality-loss<\/em> path (lossless) shaves roughly a quarter off a PNG, and the lossy path with transparency can shrink a transparent PNG to about a third of its size. For a homepage full of logos, icons, and screenshots, that compounds into a meaningfully faster page.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A caveat on honesty: 26% is Google\u2019s average across a corpus of images \u2014 your specific file can land above or below it depending on how compressible the original was. A PNG that was already small and simple has less fat to trim; a large, detailed one usually saves more. Treat the percentages as a reliable ballpark, not a guarantee for one file.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"lossless-lossy\">Lossless vs lossy WebP \u2014 which to pick<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The converter exposes a <strong>Lossless?<\/strong> toggle, and choosing correctly is the whole game.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Pick lossless WebP when:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>The image has <strong>sharp edges, text, line art, or flat color<\/strong> \u2014 UI screenshots, logos, icons, diagrams. Lossy compression is what makes text look fuzzy and edges look haloed; lossless avoids that entirely.<\/li><li>You want a <strong>drop-in PNG replacement<\/strong> with zero visible change \u2014 same pixels, ~26% smaller.<\/li><li>The PNG is your source of truth and you don\u2019t want to introduce any generational loss.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Pick lossy WebP when:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>The image is <strong>photographic or has smooth gradients<\/strong> \u2014 a hero photo, a product shot \u2014 where the eye won\u2019t notice discarded detail.<\/li><li><strong>File size is the priority<\/strong> and you can spend a little fidelity to get a much smaller file (often dramatically smaller than lossless).<\/li><li>You\u2019re delivering at web scale and a few percent of imperceptible loss is an acceptable trade for speed.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Rule of thumb:<\/strong> <em>lossless for graphics and text, lossy for photos.<\/em> If you\u2019re unsure, start lossless \u2014 it can never make the picture look worse than the PNG, and you still get the size win. For a deeper comparison of when each format earns its place, see <a href=\"https:\/\/www.xconvert.com\/blog\/png-vs-webp-vs-jpg\/\">PNG vs WebP vs JPG<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"support\">Browser support: is WebP safe to ship?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In 2026, yes \u2014 for web delivery, WebP is no longer a gamble. Per <a href=\"https:\/\/caniuse.com\/webp\">caniuse<\/a>, global browser support sits around <strong>96%<\/strong>, and every current major browser handles it:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Browser<\/th><th>WebP support from<\/th><\/tr><\/thead><tbody><tr><td>Chrome<\/td><td>version 32+<\/td><\/tr><tr><td>Firefox<\/td><td>version 65+<\/td><\/tr><tr><td>Edge<\/td><td>version 18+<\/td><\/tr><tr><td>Safari (iOS)<\/td><td>version 14+ (Sept 2020)<\/td><\/tr><tr><td>Safari (macOS)<\/td><td>version 14 added WebP; caniuse marks <strong>full<\/strong> support from 16+<\/td><\/tr><tr><td>Internet Explorer<\/td><td>never (unsupported in all versions)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Apple added WebP to Safari with <strong>iOS 14 and macOS Big Sur in September 2020<\/strong>, which is what closed the last big gap. One nuance worth knowing: older Safari 14\u201315 builds could be flaky with <strong>lossless and animated<\/strong> WebP specifically, and full coverage lands at <strong>Safari 16<\/strong> \u2014 so if you serve lossless WebP to a known older-Mac audience, that\u2019s the version to keep in mind. For the vast majority of visitors on up-to-date browsers, WebP simply works.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The only place WebP genuinely fails is legacy Internet Explorer and ancient devices \u2014 and the standard web pattern handles that gracefully with the <code>&lt;picture&gt;<\/code> element, which lets a browser fall back to the original PNG\/JPEG if it can\u2019t read WebP. If you\u2019re weighing WebP against the even-newer format, see <a href=\"https:\/\/www.xconvert.com\/blog\/avif-vs-webp-next-gen-image-formats\/\">AVIF vs WebP<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"keep-png\">When to keep PNG instead<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">WebP is a <em>web-delivery<\/em> format. It\u2019s the wrong choice for a few jobs, and PNG (or the original) wins:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Editing masters.<\/strong> Keep your editable source as PNG (or the native project file). Re-export to WebP at publish time; don\u2019t make WebP your archive format.<\/li><li><strong>Printing.<\/strong> WebP is built for screens and RGB web delivery, not print workflows \u2014 keep print-bound graphics as PNG or a print-appropriate format.<\/li><li><strong>Maximum universal compatibility.<\/strong> If a file has to open in <em>every<\/em> tool a recipient might have \u2014 old software, certain email clients, design apps that don\u2019t import WebP \u2014 PNG is still the safer lingua franca.<\/li><li><strong>Tools that won\u2019t import WebP.<\/strong> Some older editors and platforms still don\u2019t read it; check before committing a workflow to WebP-only assets.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The clean mental model: <strong>author and store in PNG, deliver to the browser in WebP.<\/strong> You get a faster site without losing your high-fidelity source.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"tool\">Convert PNG to WebP on xconvert<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.xconvert.com\/convert-png-to-webp\">xconvert PNG to WebP converter<\/a> gives you the lossless\/lossy choice directly:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1600\" height=\"1250\" src=\"https:\/\/www.xconvert.com\/blog\/wp-content\/uploads\/2026\/06\/step-01-control-63.png\" alt=\"Set Lossless? to Yes for a perfect, ~26%-smaller copy (best for logos, icons, text)\" class=\"wp-image-1335\" srcset=\"https:\/\/www.xconvert.com\/blog\/wp-content\/uploads\/2026\/06\/step-01-control-63.png 1600w, https:\/\/www.xconvert.com\/blog\/wp-content\/uploads\/2026\/06\/step-01-control-63-300x234.png 300w, https:\/\/www.xconvert.com\/blog\/wp-content\/uploads\/2026\/06\/step-01-control-63-1024x800.png 1024w, https:\/\/www.xconvert.com\/blog\/wp-content\/uploads\/2026\/06\/step-01-control-63-768x600.png 768w, https:\/\/www.xconvert.com\/blog\/wp-content\/uploads\/2026\/06\/step-01-control-63-1536x1200.png 1536w\" sizes=\"auto, (max-width: 1600px) 100vw, 1600px\" \/><\/figure>\n\n\n\n<ol class=\"wp-block-list\"><li>Open <a href=\"https:\/\/www.xconvert.com\/convert-png-to-webp\">xconvert.com\/convert-png-to-webp<\/a> and click <strong>+ Add Files<\/strong> to upload your PNG (from your computer, Google Drive, or Dropbox).<\/li><li>Open <strong>Advanced Options<\/strong> (the gear icon) to reveal the controls.<\/li><li>Set the <strong>Lossless?<\/strong> toggle: choose <strong>Yes<\/strong> for a perfect, ~26%-smaller copy (best for logos, icons, text), or leave <strong>No (Recommended)<\/strong> for a smaller lossy file (best for photos).<\/li><li>For lossy output, set the <strong>Quality Preset<\/strong> (default <strong>Very High (Recommended)<\/strong>) \u2014 or use <strong>Specific file size<\/strong> if you need to hit an exact target in MB.<\/li><li>Optionally adjust <strong>Image Resolution<\/strong> (Resolution Percentage, a preset, or exact Width\/Height) to downscale at the same time.<\/li><li>Click <strong>Convert<\/strong>, then download your WebP.<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Your file is uploaded over an encrypted connection, processed on our servers, and automatically deleted a few hours later.

For text, logos, and screenshots, pick lossless to avoid any artifacts.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Does WebP keep transparency from a PNG?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Yes.<\/strong> WebP supports the alpha channel (transparency) in <strong>both<\/strong> lossless and lossy modes, so a transparent PNG stays transparent after conversion. Google notes transparency costs only about 22% extra bytes in lossless WebP, and lossy WebP with transparency is typically around 3\u00d7 smaller than the equivalent PNG.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">How much smaller is WebP than PNG?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">Per Google, <strong>lossless WebP images are about 26% smaller than PNGs<\/strong> while keeping identical quality. Lossy WebP can be far smaller still. The exact saving depends on the image \u2014 already-simple PNGs save less, detailed ones usually save more \u2014 so treat 26% as a reliable average rather than a fixed number for every file.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Is WebP supported in all browsers?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">Effectively yes for modern browsers \u2014 global support is around <strong>96%<\/strong> (<a href=\"https:\/\/caniuse.com\/webp\">caniuse<\/a>). Chrome (32+), Firefox (65+), Edge (18+), and Safari (iOS 14+, macOS 16+ for full support) all handle WebP. The main exception is legacy Internet Explorer, which never supported it; the <code>&lt;picture&gt;<\/code> element lets you fall back to PNG for those rare cases.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Should I use WebP for printing?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>No<\/strong> \u2014 WebP is a web-delivery format optimized for on-screen RGB images, not print workflows. Keep print-bound graphics as PNG (or a print-appropriate format). The same goes for editable masters: author and archive in PNG, then export to WebP only for serving on the web.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Lossless or lossy WebP \u2014 which should I choose?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">Use <strong>lossless<\/strong> for graphics with sharp edges, text, or flat color (logos, icons, UI screenshots) \u2014 it never degrades the image. Use <strong>lossy<\/strong> for photographs and gradients, where the eye won\u2019t notice discarded detail and you get a much smaller file. When in doubt, start lossless: it can\u2019t look worse than the PNG and still saves roughly a quarter of the size.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sources<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Last verified 2026-06-25.<\/em><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/developers.google.com\/speed\/webp\">Google \u2014 WebP: A new image format for the Web<\/a> \u2014 \u201cWebP lossless images are 26% smaller than PNGs\u201d; lossy WebP 25\u201334% smaller than JPEG; alpha costs ~22% extra in lossless and lossy-with-transparency is ~3\u00d7 smaller than PNG.<\/li><li><a href=\"https:\/\/caniuse.com\/webp\">caniuse \u2014 WebP image format<\/a> \u2014 current browser support (~96% global); Chrome 32+, Firefox 65+, Edge 18+, Safari iOS 14+ \/ macOS full from 16+.<\/li><li><a href=\"https:\/\/www.macrumors.com\/2020\/06\/22\/webp-safari-14\/\">MacRumors \u2014 Apple Adds WebP Image Support in Safari 14<\/a> \u2014 confirms Safari\/iOS gained WebP with version 14 (macOS Big Sur \/ iOS 14, Sept 2020).<\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Convert PNG to WebP to shrink web images ~26% with no quality loss.
