Convert WebP to AVIF Online Free & Fast
Turn your WebP images into smaller AVIF files in seconds. No installs, no software just upload, convert and download.
This tool converts WebP images to AVIF, currently the most space-efficient image format in common use. If WebP to JPG is a trade toward broader compatibility, this is the opposite trade: AVIF typically produces smaller files than WebP at a similar quality, but with narrower browser and software support. As with any conversion between compressed formats, converting an already-compressed WebP won't match the best-case savings you'd get encoding AVIF from an uncompressed original, but it usually still reduces file size somewhat. Transparency carries over, since both formats support it. Upload your file and download an AVIF in seconds; it's deleted automatically within an hour.

- Convert to AVIF Convert Omni processes it automatically.

Why Convert WebP to AVIF
- Maximum file-size savings. AVIF often beats WebP for compression at a comparable quality level.
- Fastest possible page loads. For sites where every kilobyte matters, AVIF offers the smallest files of any widely available format.
- Transparency preserved. Like WebP, AVIF supports alpha-channel transparency, so it carries over.
- Modern browser support. Chrome, Firefox and Edge support AVIF, and Safari has supported it since 2022 (Safari 16+).
Frequently Asked Questions
Will converting WebP to AVIF always make my file smaller?
Usually, yes, but not guaranteed. AVIF generally compresses more efficiently than WebP, but since you're converting an already-compressed WebP, the savings won't be as large as encoding AVIF from an uncompressed original.
Will my transparency carry over to the AVIF?
Yes. Both WebP and AVIF support alpha-channel transparency, so it carries over cleanly.
Does AVIF work in as many places as WebP?
Not quite. WebP has slightly broader and longer-established support. AVIF works in Chrome, Firefox and Edge, and Safari since version 16 (2022), but some older browsers, email clients and software still don't display it.
Will converting to AVIF reduce my image quality?
It depends on the encoding used and your original WebP's quality. AVIF can be lossless or lossy, similar to WebP, so the outcome depends on the settings used for both the original file and the conversion.
When should I use AVIF instead of WebP?
When file size matters most and you're confident your audience uses modern browsers. If broader compatibility matters more, WebP remains the safer middle ground.
Is there a limit on how many WebP files I can convert?
The free plan allows 10 conversions a day for files up to 10 MB. Paid plans remove the daily limit and raise the file-size cap.
Is it safe to upload my WebP files?
Yes. Conversion is automated, uploads are encrypted (HTTPS/TLS) and every file is permanently deleted within 60 minutes. Your images are never used to train AI models.
