BMP

BMP Image

Raster & Vector Images

BMP is an uncompressed raster image format native to Windows. Files are large but preserve exact pixel data with no compression artifacts. Rarely used on the web due to file size.

CR2

Canon RAW CR2

Raster & Vector Images

CR2 is Canon camera RAW format containing unprocessed sensor data.

Über CR2-Dateien

Vorteilsvergleich

BMP Vorteile

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 Vorteile

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.

Einschränkungen

BMP Einschränkungen

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 Einschränkungen

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Superseded by CR3 in 2018 — format is frozen.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).

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.

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.
