Add your HEIF file
Drop one or more .heif 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.
HEIF to BMP
Converting a .heif 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.

Converting a .heif image to .bmp re-encodes the pixels for a different balance of size, quality, and support. A .heif file uses the High Efficiency Image File Format, a codec-agnostic container standard rather than a single compression scheme. Where .heic specifically means HEVC-coded content, the .heif extension signals the general container, which can in principle wrap HEVC, AV1, or even JPEG payloads along with sequences and derived images.
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.
Why convert HEIF to BMP?
The practical trigger for this conversion is usually a mismatch: with .heif, the extension alone does not reveal the codec inside, so a given .heif file may or may not decode on a given device. 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.
HEIF vs BMP at a glance
| Aspect | HEIF image (.heif) | 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 | iSO BMFF box structure: items, item properties, and item references describe images declaratively | pixels are typically stored uncompressed; optional RLE encoding exists only for 4-bit and 8-bit palette images |
| Strongest at | container-level workflows that need bursts, brackets, or multi-resolution imagery in one file | quick lossless dumps from code, since a writer takes minutes to implement |
| Weak spot | the extension alone does not reveal the codec inside, so a given .heif file may or may not decode on a given device | no effective compression, so files dwarf PNG equivalents of the same image |
Pick BMP as the output
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.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
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.
HEIF to BMP questions, answered
Will converting HEIF to BMP lose quality?
No new loss is introduced — since heif is lossy-oriented and bmp is lossless-oriented, everything the .heif 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.
Is it private to convert HEIF files here?
Yes — the .heif 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.
Where will the BMP file work?
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.
Will the BMP file be bigger or smaller than my HEIF?
Larger, sometimes much larger. A lossless .bmp must store every pixel or sample the decoder produced, without the perceptual shortcuts .heif used. Use this route for editing headroom, not for saving space.
What happens to the metadata in my HEIF file?
In .heif, eXIF and XMP are first-class metadata items in the container, with ICC profiles or CICP parameters describing color; what survives conversion depends on the tool, not the format. 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.
