Convert AVIF to WebP for broader support across older browsers and editors while keeping files small.
Convert between JPG, PNG and WebP — multiple files at once
🔒 100% private — files are processed in your browser and never uploaded to any server.
WebP has broader support in older browsers and editing software while staying compact.
Minimal at high quality — both formats compress efficiently.
No software and no sign-up. The AVIF-to-WEBP converter runs in your web browser, so it works on any device — Windows, Mac, Android or iPhone — straight from this page.
Yes. Drop in several images and they are converted together; a single file downloads directly, while a batch arrives as a ZIP.
No. Conversion happens entirely in your browser — your images never leave your device.

AVIF — AVIF. AVIF is a newer format based on the AV1 video codec, and it usually produces the smallest files of any common format at a given quality, with excellent colour and high-dynamic-range support. Its limitation is maturity: support in older browsers, editors and upload systems is still catching up, so it is not yet as universally accepted as JPG or WebP.
WEBP — WebP. WebP is a modern format from Google that supports both lossy and lossless modes, transparency and even animation. At comparable quality it is typically 25–35% smaller than JPG and much smaller than PNG, which is why it is now the default for fast-loading websites. Every current browser displays it, though some older desktop apps and upload forms still do not accept it.
Both are modern, efficient formats; WebP is supported slightly more widely by older tools.
Drop in as many AVIF files as you need and they are converted together, arriving as a single ZIP. Because the work happens on your own device rather than on a server, a batch is limited only by your own memory, and there is no queue, no daily cap and no sign-up. Private or sensitive images stay entirely with you.
Need a different conversion, or want to process a batch? The full image converter handles JPG, PNG and WebP together, and you can pair it with the compressor if the result also needs to hit a size limit.
The same AVIF reader feeds each conversion below, so whichever output you pick the file is still decoded on your own device.
If what you are starting from is not a AVIF, open the converter that matches your own file instead.
