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.

XLS

Excel Spreadsheet (Legacy)

Spreadsheets & Data

XLS is the legacy binary format for Microsoft Excel 97-2003 spreadsheets. While superseded by XLSX, it remains common in archived data and older business systems.

Über XLS-Dateien

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.

XLS Vorteile

Universal legacy — every Excel since 1997 opens .xls natively.
Binary format is compact and loads quickly.
Full support for formulas, charts, pivots, and VBA macros.
Deep integration with every accounting and ERP system of the 1990s-2000s.

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.

XLS Einschränkungen

Row/column limits are ~64× smaller than modern XLSX.
Macro-enabled variants are a notorious malware vector.
Binary corruption often means total data loss.
Cannot represent modern Excel features (dynamic arrays, LAMBDA, structured references).
Microsoft stopped evolving the format in 2007.

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.
