Compress BMP Images

BMP files are inherently uncompressed, making them very large. Our compressor applies what optimization is possible, though for significant savings we recommend converting to PNG, JPG, or WebP.

How BMP Compression Works

BMP is an uncompressed format by design — every pixel is stored at full fidelity. Our optimizer strips metadata and applies RLE encoding where supported, but savings are limited (0-10%). For meaningful compression, consider converting to a modern format.

Tips for BMP Compression

  • BMP compression savings are minimal — the format is inherently uncompressed
  • Convert to PNG for lossless compression with much smaller file size
  • Convert to JPG or WEBP for the best compression ratios
  • BMP is rarely used on the web — consider format conversion

BMP Compression FAQ

Can BMP files be compressed?

Only slightly. BMP is designed to be uncompressed. For real savings, convert to PNG (lossless, ~80% smaller) or JPG/WEBP (lossy, ~95% smaller).
