Generation loss — quality may degrade
HEIF uses lossy compression and EXR typically uses lossy mode. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Animation frames will be lost
HEIF supports animation, but EXR does not. Only the first frame (or a representative frame) will be preserved. If you need animation, consider converting to WebP or GIF instead.
Some metadata may not survive
Your HEIF file may contain EXIF, XMP metadata. EXR has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
