How to Convert BMP to HEIC

BMP's uncompressed storage means even simple images take up far more space than necessary, while HEIC's HEVC-based compression can shrink that same content dramatically, often to a small fraction of the original BMP file size. For anyone archiving a large batch of BMP screenshots, scans, or exports who wants to reclaim storage space, converting to HEIC offers some of the most aggressive compression available among everyday formats.

HEIC also supports 10-bit color depth and a full alpha channel, both beyond what BMP can store, though the main draw for this particular conversion is almost always the storage savings rather than any color or transparency benefit.

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 BMP.
3. Drag your BMP file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to BMP and the "To" format to HEIC.
5. Adjust the quality setting to balance file size against visual detail.
6. Click Convert. HEIC files are written to the output folder, fully offline.
