Compress BMP files by converting to optimized PNG. BMP is uncompressed and massive — our tool reduces file sizes by 70-90% with zero quality loss. 100% browser-based.
BMP files are lossless but massive — they store every pixel uncompressed, which makes them impractical for sharing or web use. This compressor re-encodes your BMPs to dramatically reduce file size while preserving visual quality. It's especially useful for screenshots, scanned documents, and images exported from older software that defaults to BMP format.
Why Compress BMP Files?
Massive Size Reduction
BMP files are uncompressed and huge — a 1920×1080 image is over 6MB as BMP. Converting to PNG reduces this by 70-90%.
Lossless Output
We convert BMP to PNG format, which is lossless. Every pixel is preserved exactly while dramatically reducing file size.
Resize for Extra Savings
Combine format conversion with resizing for even more dramatic file size reductions.
Completely Private
All processing happens locally in your browser. Your files never leave your device.
