Why convert BMP to HEIC?

A quick technical note: BMP uses 24-bit while HEIC uses 10-bit HDR. That difference matters most when your use case involves iPhone photos — efficient storage. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. In short, this is less about one format being 'better' and more about matching the tool to the job.

JPEG compression introduces minor quality loss — set quality to 90%+ to minimize
