Convert AVIF to WebP
Free, private, and instant — your files never leave your device.
AVIF and WebP are both modern formats built for the web, but AVIF's support history is shorter. AVIF requires Chrome 85+, Firefox 93+, or Safari 16+, while WebP has been supported across all major browsers since 2020 and has significantly broader support in desktop applications, image editors, and CMS platforms. Converting AVIF to WebP gives you a more widely compatible modern format — a practical middle ground between AVIF's exceptional compression and JPEG's decades of legacy support. The WebP will be somewhat larger than the AVIF, but still dramatically smaller than an equivalent JPEG, and full alpha transparency is preserved.

How to Use
- 1
Drop your AVIF file — the output format is already set to WebP.
- 2
Adjust the quality slider. 85% is a good default; use 90%+ for fine detail or product images.

Download the WebP. Transparency is fully preserved.
Frequently Asked Questions
Why convert AVIF to WebP instead of keeping AVIF?
Better software support — WebP is accepted by most modern image editors, CMS platforms, and all major browsers since 2020. If your target environment supports AVIF natively, keeping the original AVIF is the better choice since it's more compact.
How much larger will the WebP be than the AVIF?
Typically 20–50% larger. AVIF's compression is derived from the AV1 video codec and is generally more efficient than WebP. The WebP will still be significantly smaller than an equivalent JPEG.
Is transparency preserved when converting AVIF to WebP?
Yes. Both formats support full alpha-channel transparency. Transparent regions in the AVIF remain transparent in the WebP output.
What if my browser can't decode the AVIF?
If your browser doesn't support AVIF, the converter will show a clear error. You need Chrome 85+, Firefox 93+, or Safari 16+ to decode AVIF files. On older browsers, AVIF decoding is not available.
