RAF to BMP
Developing a .raf camera file into .bmp turns unprocessed sensor data into a finished image any app can open. Free, private, and validated — the file never leaves your browser.

Developing a .raf camera file into .bmp turns unprocessed sensor data into a finished image any app can open. A .raf file is a Fujifilm RAW photograph, notable because Fujifilm's sensors have repeatedly broken with convention, from rotated SuperCCD photosites to the X-Trans color filter array. Decoding a .raf therefore demands sensor-specific logic that generic Bayer pipelines do not have, which historically made Fujifilm support the acid test for raw converters.
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 RAF to BMP?
The practical trigger for this conversion is usually a mismatch: with .raf, x-Trans demosaicing is computationally heavier and varies in quality between converters. 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.
RAF vs BMP at a glance
| Aspect | Fujifilm RAW (.raf) | Bitmap image (.bmp) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossless — every pixel or sample is preserved exactly |
| How it stores data | proprietary header preceding a large embedded JPEG and the CFA sensor data block | pixels are typically stored uncompressed; optional RLE encoding exists only for 4-bit and 8-bit palette images |
| Strongest at | developing X-series photos where film-simulation flexibility is wanted after capture | quick lossless dumps from code, since a writer takes minutes to implement |
| Weak spot | x-Trans demosaicing is computationally heavier and varies in quality between converters | 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. A LibRaw WebAssembly decoder demosaics the sensor data in your browser and renders a developed image ready for export.
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.
RAF to BMP questions, answered
Will converting RAF to BMP lose quality?
Since raf is lossless-oriented and bmp is lossless-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .bmp itself requires.
Is it private to convert RAF files here?
Yes — the .raf file is processed inside your browser tab and never uploaded. A LibRaw WebAssembly decoder demosaics the sensor data in your browser and renders a developed image ready for export. 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 RAF?
It depends on the content: pixels are typically stored uncompressed; optional RLE encoding exists only for 4-bit and 8-bit palette images. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my RAF file?
In .raf, eXIF plus Fujifilm MakerNotes recording film simulation, dynamic-range mode, and focus data are embedded, with XMP handled through sidecars in most editors. 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.
