BMP vs MPG
A detailed comparison of BMP Image and MPEG Video (short) — file size, quality, compatibility, and which format to choose for your workflow.
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.
About BMP filesMPEG Video (short)
Video FilesMPG is a short extension for MPEG video files, commonly used for MPEG-1 and MPEG-2 video content.
About MPG filesStrengths Comparison
BMP Strengths
- 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.
MPG Strengths
- Universal legacy support.
- Trivially rewrappable to .mp4 without re-encoding.
- Low decoding overhead.
Limitations
BMP Limitations
- 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.
MPG Limitations
- Aging codec — larger files than modern alternatives.
- No HDR, no modern audio, no modern subtitles.
- Mostly legacy — not used for new production.

Frequently Asked Questions
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.

BMP files open in Windows Paint, Photos, macOS Preview, GIMP, Photoshop, and virtually any image viewer. All Windows applications support BMP natively.
BMP arquivos abrir in Windows Paint, Photos, macOS Preview, GIMP, Photoshop, e virtually any image viewer. All Windows aplicativos support BMP natively.
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.
