AVIF to WebP
Convert newer AVIF images to the more broadly compatible WebP so older software can open them too. Free, fast and secure, no sign-up. Everything runs locally in your browser and your file is never uploaded.
3 numbered images + 1 damaged file. A real processing example.
Images are processed in this tab. Download your results before closing or refreshing.

Check each image, its dimensions and file size before downloading.
Frequently asked questions
AVIF compresses even better, but some older browsers, image viewers and editors still can't open it. WebP strikes a safer balance between small size and wide support.
