About HEIF

High Efficiency Image File Format

An MPEG container standard (ISO/IEC 23008-12) from 2015 for single images and image sequences. It can hold HEVC, AV1 or other codecs, along with depth maps and bursts. Convert HEIF to JPG or PNG for apps and sites that cannot read it.

About JXL

JPEG XL

An image format standardized as ISO/IEC 18181 in 2022, with lossy and lossless modes, HDR and alpha. It can repack an existing JPG losslessly into a file about 20 percent smaller. Use it for archiving photos or for apps that support it; browser support is limited, so check before using it on the web.
