PNG to WebP Converter

Shrink a PNG dramatically without giving up its transparency.

Every tool runs entirely in your browser. Your files are never uploaded to a server.

WebP keeps the transparency PNG has while compressing far harder, often cutting file size by half or more. It is the better format for anything served on the web. Conversion runs entirely in your browser.

How to use the PNG to WebP Converter

  1. Add your PNG files. Drag them in or click to browse. Convert a whole folder at once.
  2. Choose a quality. 82 is a sensible default. For web delivery, 75 is often indistinguishable and smaller again.
  3. Convert and save. Download individually or take the batch as a ZIP.

About converting PNG to WebP

This is the conversion to reach for when a PNG is too heavy for the web but you cannot afford to lose its transparency. PNG is lossless by design, which is exactly right for logos, icons, diagrams and screenshots with crisp text, but it means a file that stores every pixel exactly — and for anything photographic that is enormously wasteful. The usual escape is JPG, except JPG has no alpha channel, so every transparent pixel is flattened onto white and a logo becomes unusable. WebP resolves the conflict: it compresses roughly as hard as JPG while keeping full transparency, and it also offers a lossless mode when exactness genuinely matters. For website assets this is close to a free win, since images dominate page weight and Largest Contentful Paint is very often an image, which Google uses directly in ranking. Two caveats keep it honest. Converting from a PNG that was itself generated from a JPG will not restore anything already lost. And older desktop software still stumbles on WebP, so it is the right format for images you serve and the wrong one for images you send to someone else to open.

Frequently asked questions

Does transparency survive?
Yes. WebP supports a full alpha channel, so transparent backgrounds stay transparent. This is the key advantage over converting a PNG to JPG.
How much smaller will the file be?
Often half or less, and for photographic PNGs the saving can exceed eighty percent. Small flat graphics with few colours save least, since PNG already handles those well.
Is WebP lossy here?
Yes, at the quality you choose. WebP also has a lossless mode, but for web delivery the lossy mode at 75 to 85 is almost always the better trade.
Will every browser display it?
Every current browser reads WebP, Safari included since 2020. Only genuinely old desktop software struggles, which is why WebP suits images you serve rather than images you email.
