OpenEXR
A high dynamic range format developed by Industrial Light & Magic and open-sourced in 2003. It stores 16-bit or 32-bit floating-point channels with lossless or lossy compression. Use it for visual effects and 3D render output that will be graded or composited without clipping highlights.
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.
