BMP vs M4V
Una comparativa detallada de BMP Image y M4V Video (Apple) — 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.
Sobre los archivos BMPM4V Video (Apple)
Video FilesM4V is Apple MPEG-4 video format, similar to MP4 but may include DRM.
Sobre los archivos M4VComparativa 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.
M4V Ventajas
- Fully MP4-compatible — one-line rename to .mp4 in most workflows.
- First-class support across Apple devices (macOS, iOS, tvOS, HomePod video).
- Supports chapters, closed captions, and multi-language audio tracks.
- Can hold Dolby Vision and HDR10+ metadata.
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.
M4V Limitaciones
- FairPlay DRM variants tie files to Apple IDs — moves to other ecosystems break playback.
- Extension is not strictly standardized — some tools flag it as unknown.
- Rarely used outside Apple distribution.

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.
