Why convert JPEG to BMP?

Because JPEG files use lossy compression and 24-bit RGB, 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.
