Why convert WebP to AVIF?

AVIF typically lands 15–25% below WebP at the same quality, and it adds what WebP cannot express: 10- and 12-bit depth, HDR, and noticeably better gradients and film grain. The gain is smaller than the jump from JPG, so it is worth spending on your largest images first instead of reconverting everything. Both formats are lossy, so this re-encode compounds whatever the WebP already lost.

Conversion happens entirely in your browser — no upload, no queue, no watermark. Drop in as many files as you like and download them individually or as a zip.

Frequently asked questions

Is it worth re-converting a WebP library to AVIF?

Only selectively. Because both are already modern lossy formats the saving is 15–25% rather than the 50% you get from JPG, and each re-encode loses a little more detail. Convert your largest and most-requested images, keep the originals, and leave small assets — icons, thumbnails — where they are.

Are my images uploaded anywhere?

No. Conversion happens inside your browser using the canvas API and a Web Worker — files never leave your device. There is no upload step, no queue and no file size limit beyond your machine's memory.

Is EXIF metadata kept in the converted image?

No — and that's a feature. Re-encoding through the canvas strips all metadata: GPS location, camera model, timestamps and color profiles. The output contains pixels only, which is usually what you want before sharing an image publicly.

Can I convert many images at once?

Yes. Drop or paste any number of files; each is converted in the background with its own progress and download button, and you can grab everything at once as a .zip archive.

Why did my image get re-compressed even converting PNG to PNG?

The converter always decodes to raw pixels and re-encodes, which is also how metadata gets stripped. For lossless targets (PNG, and GIF within its 256-color limit) the pixels stay identical; for JPEG and WebP the quality slider controls the trade-off.
