Why compress BMP files?
BMP is an uncompressed format — files are often 10–20× larger than necessary. Compressing BMP exports a smaller file in the same visual quality, saving significant disk space and transfer time.
Is it safe?
Completely. Pixvert processes everything locally in your browser using the Web Canvas API. Your images are never uploaded to any server — they never leave your device.
