Why convert HEIC to BMP?

If you work with HEIC regularly, you've probably hit compatibility walls. BMP was built for exactly this gap – Uncompressed images on Windows. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. This kind of format decision tends to matter more as a project scales up.
