Good to know
The JPG to AVIF converter converts up to 20 JPG photos at once directly in your browser via canvas into AVIF, with a quality slider and a default of 82. AVIF often achieves a significantly smaller file size than JPG for photos at similar visual quality.
Multiple results can be downloaded together as a ZIP, with a visible size comparison per file. AVIF is modern and small, but should be checked for older target browsers or applications with limited AVIF support.
Typical use cases
Compress photos for minimal file size on modern websites
Convert hero images or galleries to AVIF when the audience mostly uses modern browsers and maximum compression matters.
Batch-compress multiple JPG photos heavily
Process up to 20 JPG photos at once and download the AVIF results together as a ZIP.
Tips for better results
Check the audience's browser compatibility
AVIF is not supported by every older browser or application — check this before production use.
Increase quality if needed
For visible compression artifacts in detail-rich areas, a value higher than the default of 82 helps.
