JPG to BMP converts JPEG photos into Windows BMP (bitmap) files. BMP stores raw, uncompressed pixels, which some imaging software, scanners, and embedded devices require. Converting from JPG to BMP does not recover detail lost to JPEG compression, but it produces a clean, uncompressed bitmap of the decoded image.
This converter decodes your JPG with the browser's image engine and writes a standard 24-bit uncompressed BMP. Nothing is uploaded to a server.
