BMP vs SVGZ
Ein detaillierter Vergleich von BMP Image und Compressed SVG — 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-DateienCompressed SVG
Raster & Vector ImagesSVGZ is a gzip-compressed version of SVG vector graphics, offering the same quality in a smaller file.
Über SVGZ-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.
SVGZ Vorteile
- Tiny file sizes — huge ratio on XML-heavy SVGs.
- Drop-in replacement for .svg in every major browser.
- No client-side decompression cost — browsers handle it transparently.
- Useful for offline/embedded distribution.
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.
SVGZ Einschränkungen
- Not human-readable directly — requires decompression to edit.
- Some older software (especially Windows Explorer previews) may not recognize the extension.
- Redundant on servers that already gzip/brotli SVG in transit.
- Cannot be concatenated or edited without decompress/recompress.

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.
