About AVIF to WebP Converter
AVIF is a cutting-edge format based on the AV1 codec, with the smallest files of any common format. WebP is a modern Google format that compresses noticeably smaller than PNG or JPG at similar quality.
Converting AVIF to WebP produces a much smaller file that every modern browser supports, which helps web pages load faster. Drop your file above and it is decoded and re-encoded as WebP entirely inside your browser, so even sensitive images never leave your device.
To use it, drop your AVIF file into the upload area or click to pick one from disk. The conversion runs as a single pass — the AVIF bytes are decoded into a pixel buffer and re-encoded as WebP at a high default quality (around 92%), giving a much smaller file that stays visually nearly identical to the source. Output dimensions match the source; to resize as well, run the image resizer before or after the conversion. A typical photo converts within a second or two on a modern device.
