AVIF

Compress AVIF images

Recompress AVIF entirely in your browser with quality control, exact-size search, transparency and no file uploads.

Output strategy

Auto races WebP, AVIF and compatible JPEG after one decode. Hard-edged graphics also enter a palette PNG; photos skip that extra work. The smallest result wins, but a smaller original stays byte-for-byte and transparency is never discarded.

Compression goal

75 is a strong web default. The original stays untouched.

Resize while compressing

Aspect ratio is always preserved. Every image in a batch is resized independently.

    Everything runs locally. Images never leave this device.

    Maximum compression for modern delivery

    AVIF is designed for high compression efficiency and can retain alpha transparency. It is especially effective for large photographic assets where download weight matters more than encode time.

    Use AVIF deliberately

    AVIF encoding is CPU-heavy, so batch jobs take longer. Keep WebP or JPEG fallbacks when supporting legacy clients, email tools or image pipelines with limited AVIF support.
