Why convert HEIC to BMP?
HEIC is Apple's High Efficiency format and the iPhone default, storing photos at roughly half the size of JPEG. BMP is an uncompressed raster format that stores raw pixel data, yielding large but universally readable files.
HEIC is already a lossy format, so converting to lossless BMP will not recover detail that was discarded — but it prevents any further loss and gives you a broadly editable copy, at the cost of a larger file. BMP is readable by virtually all legacy Windows software.
Pixohub converts HEIC to BMP entirely inside your browser using the HTML canvas API and an in-browser HEIC decoder, so your images are never uploaded to a server. That makes conversion instant, completely private, and free — turn as many HEIC files into BMP as you like. Reach for BMP whenever you need maximum compatibility with legacy Windows software and raw, lossless pixels.
HEIC vs BMP: what to expect
HEIC is best for space-efficient iPhone and iPad photos, while BMP shines for maximum compatibility with legacy Windows software and raw, lossless pixels. Keep your original HEIC if you may later need the source file, and export a BMP copy for compatibility and editing.
