Both AVIF and WebP are modern, efficient web formats, but WebP enjoys slightly wider support across browsers and editing apps. Converting AVIF to WebP keeps files small and transparency intact while broadening where they will work.
AVIF is the newest mainstream web format, based on the AV1 video codec. It delivers the best compression of any widely-supported format — frequently half the size of JPG at similar quality — with transparency and HDR support.
WebP is a modern web format that supports both lossy and lossless compression, transparency and animation. It produces noticeably smaller files than JPG or PNG at the same visual quality, which is why it is now the go-to format for fast websites.

Things to keep in mind
- For typical images this conversion is straightforward, with no meaningful downsides.
Quality, file size and privacy
WebP uses adjustable compression, so you can balance quality against file size with the quality slider. A setting around 80 is visually indistinguishable from the original for most images while keeping files small.
Every conversion runs on your own device, so you can convert as many AVIF files as you like — with no limits, no watermarks and no sign-up, and nothing is ever uploaded.
Frequently asked questions
Are my files uploaded when I convert AVIF to WebP?
No. The conversion runs entirely in your browser — your AVIF files never leave your device, so it's completely private.
Is the AVIF to WebP converter free?
Yes. Converting AVIF to WebP is free and unlimited, with no sign-up and no watermark.
Can I convert many AVIF files at once?
Yes — drop multiple AVIF files and download them individually or as a single zip.
Is WebP supported by all browsers?
Yes — every modern browser (Chrome, Firefox, Edge and Safari 14+) and platforms like WordPress and Shopify display WebP. Only very old browsers need a AVIF fallback.
Why won't my AVIF file open?
AVIF is a newer format that many apps, older browsers and desktop editors can't read yet. Converting to WebP gives you a file that opens anywhere — and it happens instantly in your browser, without uploading the image.
Will the WebP file be smaller than my AVIF?
Usually yes. WebP is typically 25–35% smaller than AVIF at the same visual quality, and often more for graphics.
Do I need to install any software?
No. The AVIF to WebP converter runs in your web browser, so there's nothing to download or install — on Windows, Mac, Linux, Android or iPhone.
Will converting reduce the image quality?
You control it. WebP uses adjustable compression; a quality around 80 looks identical to the original for most images while keeping the file small.
