Why convert BMP to HEIC?
Because BMP files use uncompressed compression and 24-bit, they are not ideal for iPhone photos — efficient storage. Converting them to HEIC (lossy, 10-bit HDR) solves this. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
