BMP

BMP Image

Raster & Vector Images

BMP 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.

MPEG Video

Video Files

MPEG is an early digital video standard that formed the basis for later formats like MP4. MPEG-1 and MPEG-2 files are common in DVD rips and older digital video archives.

Vorteilsvergleich

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.

MPEG Vorteile

Universal playback on every OS, player, and DVD/TV hardware since 1995.
Proven, well-documented — three decades of spec refinement and tooling.
Best-in-class for broadcast — Transport Streams carry multiple channels, error correction, and PSI/SI metadata.
Low CPU decoding — even 1990s hardware can handle MPEG-1/2.

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.

MPEG Einschränkungen

Aging codec — MPEG-2 is 2-3× larger than H.264 at equivalent quality.
Patent licensing still active for some MPEG-2 patents in certain territories.
Consumer devices rarely default to .mpg — everything ships as .mp4 today.
No modern features (HDR, HEVC, AV1) inside classic MPEG Program Streams.

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.
