Why convert HEIC to BMP?
HEIC is the high-efficiency format iPhones and modern Apple devices use by default, storing photos at roughly half the size of JPG at the same quality. Many Windows apps and websites cannot open it, so converting to JPG or PNG makes it shareable everywhere. BMP is an uncompressed raster format from early Windows. It preserves every pixel but produces very large files, so it is mainly used for compatibility with legacy software.
- BMP has no transparency channel, so any transparent areas are flattened onto a solid background (white by default, adjustable below).
- Move to a lossless BMP file so no further quality is lost in editing — though detail already lost in the original HEIC cannot be restored.

Frequently asked questions
Is the HEIC to BMP converter free?
Yes. ConvertPix is completely free with no limits on the number of conversions, no watermarks, and no account required.
Are my HEIC images uploaded to a server?
No. Conversion happens entirely inside your web browser using your own device. Your images are never uploaded, stored, or seen by anyone.
Will converting HEIC to BMP improve quality?
Converting to BMP stops any further quality loss, but it cannot recover detail already removed by the original HEIC compression. The result matches your source as closely as possible.
Does BMP support transparency?
No, BMP does not support transparency. Transparent pixels are filled with a solid background colour during conversion.
What is the largest file I can convert?
You can convert HEIC images up to 5 MB. Because processing is done on your device, very large images depend on your device's available memory.
