Choosing between BMP (BMP Image, image/bmp) and CR2 (Canon RAW CR2, image/x-canon-cr2) depends on your target workflow, compression efficiency, and device support. Below is our side-by-side technical benchmark and instant bidirectional converter.
BMP vs CR2 at a glance
BMP vs CR2| Dimension | .BMP | .CR2 |
|---|---|---|
| Format Name | BMP Image (.bmp) | Canon RAW CR2 (.cr2) |
| Format Family | Raster & Vector Images | Raster & Vector Images |
| Primary MIME | image/bmp | image/x-canon-cr2 |

| Pipeline Role | Read & Write | Source Input |
When should you use BMP vs CR2?
.BMP Use when…
Use BMP (BMP Image) when your pipeline requires native image/bmp compatibility, predictable rendering, or specialized Raster & Vector Images editing support.
.CR2 Use when…
Use CR2 (Canon RAW CR2) when you need image/x-canon-cr2 delivery, cross-platform Raster & Vector Images distribution, or streamlined storage.

| Color depths | 1, 4, 8, 16, 24, 32 bits per pixel | — |
| Byte order | Little-endian | — |
| Extension | — | .cr2 |
| Container | — | TIFF/EP with Canon private tags |
| Bit depth | — | 14-bit (most bodies); 12-bit (some) |
| Successor | — | .cr3 (EOS M50 onward, 2018) |
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.
.CR2 Strengths
- Mature — 13 years of camera bodies and tooling.
- Preserves every bit of Canon sensor data for post-processing.
- Embedded JPEG preview makes browsing fast.
- Supported by every major raw processor.
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.
.CR2 — Limitations
- Proprietary — no official spec, tool support depends on reverse engineering.
- Canon-only tags (Picture Styles, DPP adjustments) are lost when processed outside DPP.
- Superseded by CR3 in 2018 — format is frozen.
- File sizes are large (20-40 MB typical).
Technical deep dive: BMP vs CR2
Both BMP and CR2 serve distinct roles in modern digital pipelines. With KaijuConverter you can transcode between .bmp and .cr2 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 CR2 (Canon RAW CR2) uses image/x-canon-cr2 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 CR2.
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.
CR2 (Canon RAW CR2) 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 CR2 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 CR2 natively. On mobile, iOS Photos and Google Photos display CR2 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 CR2 to JPG or CR2 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).
