BMP vs RAW
Ein detaillierter Vergleich von BMP Image und Generic RAW Image — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
BMP Image
Raster & Vector ImagesBMP 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.
Über BMP-DateienGeneric RAW Image
Raster & Vector ImagesRAW is a generic term for files containing minimally processed data from a camera image sensor. Various camera manufacturers use proprietary RAW variants, but the term broadly refers to any unprocessed sensor capture that retains maximum editing flexibility.
Über RAW-DateienVorteilsvergleich
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.
RAW Vorteile
- Every bit of sensor data preserved for post-processing latitude.
- Higher bit depth (12-16 bits) than JPEG (8-bit) — smoother gradients.
- Non-destructive editing in raw processors.
- Rich metadata (EXIF, makernotes, camera settings).
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.
RAW Einschränkungen
- Proprietary per brand — Canon CR2 will not open in a pure-Canon-free processor.
- Huge files compared to JPEG.
- Requires dedicated software (Lightroom, Capture One, Darktable, etc.).
- No universal standard — DNG aims to solve this but adoption is partial.

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.
