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.

TGA (Targa) is a raster graphics format used in game development and video editing.

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.

TGA Vorteile

Extremely simple — trivially easy to read and write.
Lossless with optional RLE compression.
Supports 8, 16, 24, and 32-bit color with alpha channel.
Universal in legacy game development and 3D rendering pipelines.

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.

TGA Einschränkungen

No metadata, no color profile, no gamma correction.
Aging — PNG and EXR cover its use cases with better compression.
Bottom-up pixel order trips up newcomer parsers.
Not a web format — browsers don't display TGA natively.

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.

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.
