PNG to WebP

Runs in your browser

Convert a PNG image to WebP for smaller files with transparency kept intact.

What is a PNG to WebP?

WebP is a modern image format that generally beats both PNG and JPG at the same visual quality: it supports lossless compression like PNG (typically 20-30% smaller for the same image) and lossy compression like JPG, plus transparency in both modes — something JPG cannot do at all. It's supported by every major browser released in the last several years.

Converting a PNG to WebP is close to a free win for web use: transparency is preserved, and file size typically drops noticeably even at high quality. The main reason not to use WebP is compatibility with older tools or specific platforms that still expect PNG or JPG specifically — check where the image is going before converting.

How to use it

  1. Drop a PNG file onto the panel, or click to browse.
  2. Adjust the quality slider — WebP looks good even in the 75-90% range, well below where JPG starts showing artefacts.
  3. The converted WebP preview appears automatically, with transparency preserved.
  4. Click Download WebP to save the result.

Frequently asked questions

Does WebP keep transparency like PNG?
Yes — WebP supports a full alpha channel in both its lossless and lossy modes, unlike JPG. Transparent areas in your source PNG stay transparent in the WebP output.
Is WebP supported everywhere?
All major browsers (Chrome, Firefox, Safari, Edge) have supported WebP for encoding and decoding since roughly 2020. Some older software, specific CMS plugins, and certain print or design tools may still expect PNG or JPG, so check your destination before converting an entire library.
How much smaller is WebP than PNG?
It varies by image, but WebP's lossless mode is typically 20-30% smaller than PNG for the same pixels, and its lossy mode can be dramatically smaller still at a quality setting most people can't distinguish from the original.
