About BMP Compression
BMP (Bitmap) files are completely uncompressed — every single pixel is stored as raw RGB data. A 1920×1080 BMP is roughly 6 MB regardless of content. This makes BMP one of the most compressible formats.
CocoConvert's BMP compressor applies RLE (Run-Length Encoding) compression, which is lossless and dramatically reduces file size for images with large areas of similar colour. Even complex photographs typically see 50-80% reduction.
If your workflow allows it, consider converting BMP to PNG (lossless) or WebP (near-lossless) for even better compression — CocoConvert offers these conversions too.
BMP compression is near-instant since the algorithm is simple and the data is already uncompressed. Batch process hundreds of BMP files in seconds.

Frequently Asked Questions
What are the limits for BMP compression?
CocoConvert lets you compress BMP files with no signup required. You get 5 files per hour (up to 250 MB each) on the starter tier. Pro users get 100 files per hour and 5 GB per file.
How much can I reduce BMP file size?
Typical BMP compression reduces file size by 50-80%, depending on the original file and quality settings. Tip: RLE compression is always lossless for BMP.
Does compression affect BMP quality?
CocoConvert gives you full control over the quality-size trade-off. Higher quality settings preserve more detail; lower settings produce smaller files. For lossless formats, compression is always bit-for-bit identical.
Is my BMP file secure?
Absolutely. Files are processed on isolated servers in Germany, encrypted in transit via TLS, never analysed or shared, and permanently deleted within 24 hours.
Can I batch compress multiple BMP files?
Yes! You can compress up to 5 files per hour on the starter tier. Pro users get 100 files, Business API users get 200. All files are processed in parallel.
