Convert HEIC to BMP Online
HEIC is the default photo format on iPhone since iOS 11 — great for storage, poorly supported outside Apple devices. Converting to BMP happens instantly, right in your browser. BMP stores pixels uncompressed — large files, but opens in essentially anything, including very old software.
Why Convert HEIC to BMP
iPhones save photos as HEIC by default, so moving them to a Windows PC, an older app, or a web upload form often hits a compatibility wall without any clear explanation why. Converting to BMP gets you guaranteed compatibility with very old or specialized software — done instantly, for free, without installing anything or creating an account.

Converting your HEIC file to BMP happens in three steps, entirely on your device: your browser reads the HEIC file into memory, decodes and re-encodes it as BMP using built-in browser technology (Canvas and WebAssembly), and hands you the finished file as a direct download.
At no point does the file get sent to a server. There’s no upload step to intercept, no account that could be breached, and nothing stored after you close the tab — the conversion simply couldn’t leak your file even if something went wrong, because it never left your browser in the first place.
