Choosing between BMP (BMP Image, image/bmp) and RAF (Fujifilm RAW, image/x-fuji-raf) depends on your target workflow, compression efficiency, and device support. Below is our side-by-side technical benchmark and instant bidirectional converter.
BMP vs RAF at a glance
BMP vs RAF| Dimension | .BMP | .RAF |
|---|---|---|
| Format Name | BMP Image (.bmp) | Fujifilm RAW (.raf) |
| Format Family | Raster & Vector Images | Raster & Vector Images |
| Primary MIME | image/bmp | image/x-fuji-raf |
| Developer / Year | Microsoft & IBM (OS/2 + Windows 1.0) (1985) | Fujifilm (2003) |
| Pipeline Role | Read & Write | Source Input |
When should you use BMP vs RAF?
.BMP Use when…
Use BMP (BMP Image) when your pipeline requires native image/bmp compatibility, predictable rendering, or specialized Raster & Vector Images editing support.
.RAF Use when…
Use RAF (Fujifilm RAW) when you need image/x-fuji-raf delivery, cross-platform Raster & Vector Images distribution, or streamlined storage.
Technical Specifications
| Specification | .BMP | .RAF |

| MIME type | image/bmp | image/x-fuji-raf |
| Extensions | .bmp, .dib | — |
| Compression | None (typical); RLE 4/8 bit (rare) | — |
| Color depths | 1, 4, 8, 16, 24, 32 bits per pixel | — |
| Byte order | Little-endian | — |
| Extension | — | .raf |
| Container | — | Fujifilm proprietary TIFF-like |
| Sensor arrays | — | X-Trans (APS-C), Bayer (GFX medium-format) |
| Bit depth | — | 14-bit (X-series); 16-bit (GFX) |
Strengths Comparison
.BMP Strengths
- Dead-simple format — trivially easy to read and write.
- Lossless and uncompressed — perfect bit-exact pixel storage.
- Universally supported in Windows applications since 1985.
- Supports 1, 4, 8, 16, 24, and 32-bit color depths.
.RAF Strengths
- Full 14-bit (most bodies) or 16-bit (GFX) sensor data.
- Film simulation recipe stored in metadata.
- X-Trans sensor produces distinctive moiré-free rendering.
- Supports every classic Fuji film-simulation look.
Limitations
.BMP — Limitations
- Enormous file sizes — no meaningful compression in typical use.
- Not a web format — browsers support it but nobody serves BMPs over HTTP.
- No metadata support (no EXIF, no ICC profile in practice).
- Multiple header versions mean "a BMP" is ambiguous — parsers must handle several variants.
.RAF — Limitations
- X-Trans demosaicing is the hardest raw problem to solve cleanly.
- Third-party tools rarely match Fuji's own rendering.
- Proprietary with no official spec.
- GFX RAF files are massive (150+ MB per shot).
Technical deep dive: BMP vs RAF
Both BMP and RAF serve distinct roles in modern digital pipelines. With KaijuConverter you can transcode between .bmp and .raf in seconds while preserving metadata and structural fidelity.
Frequently Asked Questions
BMP (BMP Image) uses MIME type image/bmp in the Raster & Vector Images family, whereas RAF (Fujifilm RAW) uses image/x-fuji-raf in the Raster & Vector Images family. Each optimizes for different trade-offs in file size, fidelity, and software compatibility.
Yes. KaijuConverter uses tuned encoding profiles to preserve maximum visual, audio, or document fidelity when converting between BMP and RAF.
BMP (Bitmap) is a raster image format developed by Microsoft for Windows. It stores images with no compression by default, resulting in large file sizes but pixel-perfect quality. It has been part of Windows since version 1.0.
RAF (Fujifilm RAW) is an image format used to store raster graphics — a two-dimensional grid of pixels describing a picture. It is part of the raster & vector images family and designed around a specific trade-off between file size, visual fidelity, and feature support (transparency, colour depth, compression type). Photographers, web designers, and content creators choose RAF when its particular strengths match the publishing target.
BMP files open in Windows Paint, Photos, macOS Preview, GIMP, Photoshop, and virtually any image viewer. All Windows applications support BMP natively.
Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open RAF natively. On mobile, iOS Photos and Google Photos display RAF in the gallery when supported by the OS. If the format is rare or new, convert to JPG or PNG first — both are universally readable — using our RAF to JPG or RAF to PNG converter.
PNG is better than BMP in almost every scenario since it provides lossless compression (smaller files), transparency support, and wider cross-platform use. BMP is mainly relevant for legacy Windows applications.
Yes. Every .bmp file uploaded to KaijuConverter is transferred over TLS 1.3, processed in an isolated container with SHA-256 verification, and automatically deleted within 30–60 minutes (or immediately with 1 click).
