PNG to WebP converter
Heavy PNGs slow a page down. Convert logos, icons and screenshots to WebP and keep their transparent backgrounds.
Add images: JPG, PNG, WebP, HEIC, AVIF, GIF, BMP or SVG.

Transparent areas become white in JPG.
Your files are processed on your own device and never uploaded.
How to use it
- Add your PNG files with ‘Choose files’, or drop them on the page.
- WebP is already picked under ‘Convert to’. Keep ‘Quality’ at 90, where it starts, or move the slider, then click ‘Convert’.
- Click ‘Download’ beside a file, or ‘Download all (ZIP)’ to grab the whole batch.
Good to know
Product shots, icons and screenshots saved as PNG add up fast, and on a slow connection they decide how long a visitor stares at an empty space. WebP typically describes the same picture in fewer bytes and still allows transparent pixels, so a logo that has to sit on any background color keeps working. Shops, blogs and portfolios often make this swap as the last step before publishing.
‘Quality’ decides how hard the pixels are squeezed. Sharp text and thin lines in a graphic show damage first, so 90 is a sensible start, while photographs tolerate a lower number. Zoom in on the result before it goes live and hang on to the PNG originals: you will want them for later edits, and a few older programs cannot read WebP. The Compress image tool offers a similar route, turning PNG files into WebP with an optional maximum width.
Questions and answers
Will the transparent parts of my PNG survive?
Yes. WebP supports transparency, and the converter does not fill the background when the output is WebP.
How much lighter will the files be?
It depends on the picture, but WebP is usually smaller than PNG, and a lower ‘Quality’ trims further. The file list shows each new size beside the old one, so one test file tells you.
Does every program open WebP?
Current Chrome, Edge, Firefox and Safari show it, but some older desktop programs and services do not. Keep your PNGs for those and publish the WebP online.
