About this tool

About AVIF Converter

The AVIF Converter decodes AVIF images to PNG or JPG, and encodes PNG or JPG to AVIF where the browser supports it, showing a compatibility note when encoding is unavailable. AVIF offers excellent compression for modern web delivery.

AVIF can be significantly smaller than JPG or WebP, but support is uneven. Converting locally lets you produce or open AVIF depending on what your browser can do, with no upload.

Choose the direction: decode AVIF to PNG/JPG, or encode to AVIF.
