Why convert HEIC to BMP?
- BMP is supported far more widely than HEIC, so the file is easier to open, share and upload.
- BMP is lossless, so the converted image loses no further detail when you edit and save it again.
- BMP is made for older Windows programs, embedded devices and tools that need raw pixels.
What to expect when converting HEIC to BMP
- Converting can’t bring back detail that HEIC compression already removed: the BMP is an exact copy of the image as it is, usually in a bigger file.
- High-dynamic-range and wide-colour detail is converted to standard 8-bit colour.
