BMP vs CDR
Ein detaillierter Vergleich von BMP Image und CorelDRAW — 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-DateienCorelDRAW
Raster & Vector ImagesCDR is the native vector graphics format for CorelDRAW, a popular illustration and graphic design application. It supports multi-page documents, layers, color management, and both vector and bitmap content in a single file.
Über CDR-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.
CDR Vorteile
- Native format for CorelDRAW, an industry standard in signage and prepress.
- Multi-page documents (unlike Illustrator's art boards).
- Strong color management (CMYK, Pantone spot, ICC).
- Large market share in Eastern Europe and niche print industries.
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.
CDR Einschränkungen
- Proprietary, unstable format — versions drift dramatically.
- No Adobe Illustrator interoperability; SVG export is the compatibility path.
- Third-party CDR import support (Inkscape, etc.) is partial.
- File sizes balloon quickly with embedded photos.

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.
