// ABOUT HEIC
HEIC (High Efficiency Image Container) is Apple's default camera format on iPhone and iPad since iOS 11. It uses the HEVC video codec to achieve roughly 50% better compression than JPEG at equivalent quality. HEIC supports transparency, depth maps, and burst sequences. However, HEIC encoding requires a commercial HEVC licence, so this tool supports HEIC as an input-only format.
// ABOUT BMP
BMP is an uncompressed raster format developed by Microsoft. It stores raw pixel data with no compression whatsoever, resulting in very large files but universal compatibility across Windows applications. BMP is most useful when a downstream tool or legacy application requires raw, uncompressed pixel data.
// WHY CONVERT
Converting HEIC to BMP is useful when you need your image in a format suited for legacy Windows applications, game engines requiring uncompressed textures, hardware tools, and scenarios where decompression overhead must be zero. Since BMP stores raw pixel data, the resulting file will be significantly larger than the HEIC source, but no quality is lost. Image Toolz runs the entire conversion directly in your browser. Nothing is uploaded to any server — your files remain completely private on your device. The tool handles images up to 200 MB and most conversions complete in under a second.
// FAQ
What is HEIC?
HEIC is Apple's default photo format on iPhone and iPad, using HEVC compression to produce small, high-quality files.
What is BMP?
BMP is an uncompressed Windows format storing raw pixel data. Files are very large but universally compatible with Windows applications.
Will converting HEIC to BMP lose quality?
No additional loss. The BMP is a lossless copy of the decoded HEIC pixels. HEIC compression artifacts remain but no new loss is introduced.
Is it safe to convert my files here?
Yes. All conversion runs entirely in your browser. Your images are never uploaded to any server and nothing leaves your device.
