Why convert HEIC to BMP?

Because HEIC files use lossy compression and 10-bit HDR, they are not ideal for Uncompressed images on Windows. Converting them to BMP (uncompressed, 24-bit) 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.
