How to Convert HEIC to BMP

HEIC's HEVC-based compression makes it efficient for storing iPhone photos, but that same compression means it requires specific decoding support that many older or simple programs don't have. BMP, by contrast, stores pixel data in a basic uncompressed grid that virtually any image-handling software can read directly without needing a HEVC decoder, which is why some legacy Windows applications or embedded systems specifically expect BMP input.

Converting HEIC to BMP trades away HEIC's storage efficiency entirely — BMP files are typically far larger than the source HEIC, often by a factor of 10 or more — but it guarantees the image opens in software that has no HEIC support whatsoever.

1. Install Turbo Batch Image Converter Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single HEIC file.
3. Drag your HEIC file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to HEIC and the "To" format to BMP.
5. Click Convert. BMP files are written to the output folder, fully offline.
