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 JP2
JPEG 2000
A wavelet-based image format standardized in 2000, with lossy and lossless modes. It never caught on in web browsers, but digital cinema, medical imaging and map archives use it. Convert from JP2 to get a file ordinary apps can open; convert to it when an archive or imaging system requires it.
