Modern image formats (WebP, AVIF) cut file sizes 25-50% vs JPG/PNG at the same quality. This converter does the transformation in your browser using Canvas, drop a JPG, get a WebP, no upload.

Browser support

WebP is supported by every modern browser (Chrome, Firefox, Safari 14+, Edge). For Safari 13 and below, use a <picture> element with JPG fallback:

  <img src="img.jpg" alt="..." />
</picture>

Frequently asked questions

How much smaller is WebP vs JPG? +

Typically 25-35% smaller at the same visual quality. For images with sharp edges (logos, screenshots, line art), WebP can be 50-70% smaller than PNG while keeping lossless quality.

Will WebP break in older browsers? +

Modern browsers all support WebP (Chrome since 2010, Firefox since 2019, Safari since 14, Edge since launch). For older Safari, use a <picture> element with JPG fallback, example in the page footer.

Does this preserve transparency? +

Yes. WebP supports alpha channel like PNG. PNGs with transparency convert to WebP cleanly without losing the transparent regions.

Can I batch convert? +

Yes, drop up to 20 files at once. Each is converted independently and shown with original vs new file size + a download button. Nothing leaves your browser.
