BMP vs WMF
Una comparativa detallada de BMP Image y Windows Metafile — tamaño de archivo, calidad, compatibilidad y cuál elegir según tu flujo de trabajo.
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.

Raster & Vector ImagesWMF (Windows Metafile) is a legacy Windows vector graphics format.
Sobre los archivos WMFComparativa de ventajas
BMP Ventajas
- 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.
WMF Ventajas
- Native Windows vector format.
- Efficient for line-art and diagrammatic images.
- Preserved in Office clipboard workflows.
Limitaciones
BMP Limitaciones
- 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.
WMF Limitaciones
- Windows-only — poor Mac and Linux support.
- 2005 security vulnerability eroded trust.
- 16-bit coordinates in original WMF limit canvas size.
- Largely superseded by SVG for modern vector exchange.
- Not a web format.

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.
