Convert exr to heic
A browser can't do this one — here is what it can do.
Desktop app only
Nothing that runs in a tab can write heic from exr. This pair is waiting on the desktop build, which hands the job to the real command-line tools.

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 HEIC
HEIC (HEVC-coded HEIF image)
HEVC-compressed images in a HEIF container. iPhones have saved photos this way by default since iOS 11 in 2017, at much smaller sizes than JPG, but Windows and many websites cannot open them without extra codecs. Convert HEIC to JPG or PNG to open iPhone photos on Windows, upload them to sites that reject HEIC, or share them.
