About AVIF To WEBP Converter Online
AVIF (AV1 Image File Format) is a next-generation format based on the AV1 video codec. It delivers exceptional compression — often 50% smaller than JPEG — while supporting transparency, HDR, and wide color gamut.
Converting to WebP is the standard way to reduce image file size for the web without sacrificing visual quality. Smaller images mean faster page loads, lower bandwidth costs, and better Core Web Vitals scores.
This tool converts your AVIF images to WebP directly in the browser. Upload your file, choose a quality preset if available, and download the converted result instantly.

How to convert AVIF to WebP
Upload your AVIF file
Click the upload area or drag a AVIF image. The conversion runs locally in the tool pipeline.
Set quality (optional)
The Quality slider sets WebP lossy compression. 80 is a sensible default — the result will be noticeably smaller than a JPEG at the same visual quality. Set to 100 for near-lossless output.
Convert
Press Convert. Sharp encodes the output as WebP, preserving alpha transparency if the source has it.
Download the WebP
Click Download to save the .webp file. WebP is supported by all modern browsers and produces smaller files than JPEG or PNG for both photos and graphics.
