AVIF is already highly efficient, but further compression can reduce file size for bandwidth-critical applications. Adjust quality to find the right balance.
Convert AVIF to WebP for broader compatibility, JPEG for legacy support, or PNG for lossless output.
All AVIF compression runs in your browser session. Your images are not uploaded to any server during the process.
Further optimize AVIF assets for the fastest possible page loads.
