Convert images to WebP

Make JPG and PNG images smaller for the web by turning them into WebP.

or drop them here · paste with Ctrl+V

What it does

WebP is an image format made for websites: at the same visible quality, a WebP is usually noticeably smaller than a JPG, and far smaller than a PNG photo, so pages load faster. Convert a batch of JPG, PNG or GIF images at quality 80, the usual setting for the web, and see how much each one shrank. Transparent PNG backgrounds stay transparent. Every modern browser can show WebP images.

How to use it

How it works
  1. Click “Choose images”, drop your JPG, PNG or GIF files onto the box, or paste with Ctrl+V (⌘+V on a Mac).
  2. They’re converted to WebP straight away, in your browser.
  3. Download each WebP file, or all of them together as a ZIP.

Common uses

  • Speeding up a website or blog by serving lighter images
  • Improving a page’s Lighthouse or PageSpeed score, which flags images not in a modern format
  • Shrinking transparent PNG logos and icons while keeping the transparency

Tips

  • Photos usually shrink the most. Simple graphics that were already small PNGs can occasionally come out bigger, and the size change next to each file shows it.
  • Resize images to the size they’re shown on your page first; a 4000-pixel photo is wasted in an 800-pixel column, whatever the format.
  • Keep your original files: converting back from WebP won’t restore detail that was compressed away.

Questions

Why doesn’t it work on my iPhone or in Safari?

Safari can show WebP images but can’t create them, and on iPhone and iPad every browser, Chrome included, runs on Safari’s engine. The tool tells you instead of saving a wrong file. Use Chrome, Edge or Firefox on a computer or an Android phone.

Does WebP keep transparency?

Yes. Transparent areas of PNG and GIF images stay transparent in the WebP file.

What about animated GIFs?

Only the first frame is converted, so the result is a still image.

Can every browser show WebP images?

All current versions of Chrome, Edge, Firefox and Safari display WebP, on computers and phones. Very old browsers, such as Internet Explorer, don’t.
