Add your HEIC file
Drop one or more .heic files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Converting a .heic image to .bmp re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting a .heic image to .bmp re-encodes the pixels for a different balance of size, quality, and support. A .heic file contains imagery compressed with the HEVC (H.265) video codec inside the HEIF container — it is the specific HEVC-coded flavor of HEIF. Apple made it the default camera format on iPhone, so most .heic files people encounter are iPhone photos that roughly halve the storage of equivalent JPEGs.
A .bmp file is the Windows bitmap format: raw pixel rows written to disk with a small header and, in the common case, no compression at all. Its brute simplicity makes .bmp trivial to read and write from any programming language, which is why it persists in tooling, embedded systems, and quick debugging dumps. For this route the practical draw is dead-simple structure with no decoding step at all and exactly lossless — what you write is what you read — balanced against no effective compression, so files dwarf PNG equivalents of the same image, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .heic, hEVC patent licensing means Windows users must install a codec (historically a paid $0.99 extension) to view files. Switching to .bmp buys you dead-simple structure with no decoding step at all, which is why it is the better fit for quick lossless dumps from code, since a writer takes minutes to implement. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | HEIC image (.heic) | Bitmap image (.bmp) |
|---|---|---|
| Format type | Lossy — discards detail it judges invisible to shrink files | Lossless — every pixel or sample is preserved exactly |
| How it stores data | pixels are HEVC intra-coded, commonly at 10-bit depth on recent iPhones | pixels are typically stored uncompressed; optional RLE encoding exists only for 4-bit and 8-bit palette images |
| Strongest at | default photo capture on iPhone and iPad, halving camera roll storage | quick lossless dumps from code, since a writer takes minutes to implement |
| Weak spot | hEVC patent licensing means Windows users must install a codec (historically a paid $0.99 extension) to view files | no effective compression, so files dwarf PNG equivalents of the same image |

Select .bmp in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if BMP is selectable, the route is real and validated.
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid BMP file. Outputs keep the original filename with the .bmp extension.
No new loss is introduced — since heic is lossy-oriented and bmp is lossless-oriented, everything the .heic file still contains is carried over exactly. What was already discarded by the original lossy encode cannot be recovered, though; converting to .bmp does not "restore" quality.
Yes — the .heic file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Windows treats BMP as a native citizen, and macOS, Linux, and all major browsers open it without complaint. The format's problem is never support but waste: emailing or hosting uncompressed bitmaps burns bandwidth for zero benefit, so converting to PNG is almost always an upgrade.
Larger, sometimes much larger. A lossless .bmp must store every pixel or sample the decoder produced, without the perceptual shortcuts .heic used. Use this route for editing headroom, not for saving space.
In .heic, full EXIF (including GPS and orientation) and XMP are carried as container-level metadata items, and Apple additionally embeds depth and gain-map auxiliary data that most converters discard. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
