JPG to AVIF Converter
Convert JPG photos to next-generation AVIF for far smaller files at the same quality.
AVIF uses the modern AV1 codec to compress images far more efficiently than JPG — typically 30–50% smaller at comparable quality, with optional transparency and HDR.
Encoding happens in your browser with no upload, so even large batches stay private.
