How it works
- Drop your AVIF files here, or select a whole folder.
- Each AVIF is decoded and re-encoded as WebP — right in your browser.
- Transparency, if present, carries over automatically.
- Download the WebP files individually, or as one ZIP.
This is a deliberate step backward on compression, and that's fine — plenty of CMS themes, email platforms, and marketplace upload forms accept WebP but reject AVIF outright. Rather than fight the platform, converting AVIF to WebP gets a modern, still-efficient format that's supported almost everywhere. This tool decodes the AVIF and re-encodes it as WebP entirely in your browser, transparency preserved. Expect the WebP to end up somewhat larger than the AVIF it came from — that trade for compatibility is the whole point of this conversion, not a flaw.
Why use convert.pics?
- Works with CMS themes, email platforms, and forms that reject AVIF outright.
- Transparency preserved, same as the source AVIF.
- No upload: decoding and re-encoding both happen locally.
- Batch conversion for a whole folder of AVIF files at once.
Frequently asked questions
Why would I convert AVIF to WebP?
Usually for compatibility — a CMS theme, an email platform, or a marketplace upload form accepts WebP but rejects AVIF outright. Converting is the practical fix when you can't change the platform's requirements.
Does WebP have wider support than AVIF?
Marginally, mostly outside browsers — some CMS plugins, email clients, and older editing software support WebP but not yet AVIF. In modern browsers themselves, support for the two is now roughly equivalent.
Will the WebP file be larger?
Usually yes, somewhat — AVIF's compression is generally more efficient, so converting to WebP typically gives up some of that efficiency in exchange for broader compatibility.
Does the conversion keep transparency?
Yes. Both AVIF and WebP support a full alpha channel, and the conversion carries transparency over exactly.
What if the AVIF file is animated?
Unlike JPG or PNG, WebP can actually store animation — but this tool's v1 still only converts the first frame of an animated AVIF, flagged clearly in the result. Keep the original AVIF for now if the animation itself matters, rather than expecting the WebP output to loop.
