JPG to WebP Converter

FAQ

Which browsers support WebP encoding?+

Chrome, Firefox, Edge, and most evergreen browsers. Safari added canvas WebP encode in recent versions.

What if WebP is unsupported?+

The convert action is disabled with an explanation. No mislabeled PNG is offered as WebP.

Are files uploaded?+

No. Encoding uses canvas.toBlob() locally.

How much smaller will WebP be than JPEG?+

Depends on content and quality setting. Photos often shrink noticeably; already-optimized JPEGs may see smaller gains. Compare download sizes after convert.

Does WebP output keep JPEG artifacts?+

Yes. WebP re-encodes decoded pixels — existing JPEG compression noise remains. You cannot recover quality lost in the original JPG.
