Free Online JPEG to AVIF Image Converter

Convert JPG (JPEG) images to the next-generation AVIF (AV1 Image File Format) for dramatically smaller file sizes with better visual quality. AVIF uses AV1 video compression technology to achieve up to 50% better compression than JPEG at equivalent quality - plus it supports alpha transparency, HDR, and wide color gamut that JPEG cannot provide.

This tool supports both single-file conversion and local batch mode. In batch mode, you can convert multiple JPG images to AVIF at once directly in your browser without uploading to the server, and download all converted files in a ZIP archive.

JPEG has been the web standard for decades, but AVIF is rapidly gaining support across Chrome, Firefox, Safari, and Edge. Converting your JPG images to AVIF reduces bandwidth usage, speeds up website loading, and provides sharper visuals at lower file sizes. Use the quality slider (0-100) to fine-tune the compression ratio to your needs.

By default, this tool processes multiple files locally in your browser. If you want to use the server-side converter for a single file, switch to server-side mode.

If you want to make an animated AVIF file from multiple JPG images, use the AVIF Maker tab instead.
