About WebP to AVIF conversion
WebP is an image format based on VP8 encoding released by Google in 2010. AVIF is an image format based on AV1 encoding released by the Alliance for Open Media in 2019. Both support lossy compression, lossless compression, alpha channels and animation. This conversion converts WebP to AVIF, which offers a higher compression ratio.
At the same visual quality, AVIF file size is approximately 71% of the original WebP file. The conversion preserves the input file's alpha channel and animation information, retains input EXIF metadata, and the quality parameter directly affects the output file size and visual quality.
The converted output is compatible with Chrome 85+, Firefox 93+, Safari 16+ and newer browser versions. It can be used to optimize frontend website assets, reduce bandwidth consumption during page loading, and improve page load speed.

FAQ about WebP → AVIF
Will conversion reduce image quality?
AVIF converted at the same file size delivers better quality than the original WebP. If you keep the same quality, the output AVIF will be smaller than the original WebP. The conversion is processed based on the Sharp engine, and no additional quality loss occurs during the process.
Will the alpha channel be preserved?
The alpha channel of the input WebP is preserved. If the input WebP is an animated format, the output AVIF animation sequence will also be preserved, with no information loss.
What is the maximum single file size limit?
The maximum single file size for this tool is 50MB, and only one file can be converted per session. This tool is free to use, outputs no watermarks, and requires no account registration.
Will my files be stored?
Conversion is completed on the server side, and files are uploaded via HTTPS. After conversion completes, the server immediately deletes both the source file and the output file, and does not store any files.
