Why convert JPG to BMP?
Some old Windows software, embedded tools and legacy pipelines only accept the uncompressed BMP format. Converting a JPG to BMP re-encodes it as raw, uncompressed pixel data — much larger than the JPG, but readable by software that's never heard of JPEG compression. It happens entirely in your browser; nothing is uploaded.
JPG vs BMP at a glance
JPG is the universal photo format — opens in every app, device and website made since the early 90s. BMP is Windows' raw bitmap format — pixel data stored uncompressed, which makes files enormous.

JPG to BMP — frequently asked questions
Is this JPG to BMP converter really free?
Yes — completely free, with no sign-up, no watermarks and no daily limits.
Are my JPG files uploaded to a server?
No. The conversion happens entirely on your device using your browser's built-in image engine. Your JPG files never leave your computer or phone — which is also why the conversion is nearly instant.
Will converting JPG to BMP lose quality?
No. BMP is a lossless format, so the converted file keeps every pixel exactly as decoded from your JPG.
Why is my BMP so much bigger than the JPG?
BMP stores every pixel's color raw with no compression at all, while JPG discards detail to compress heavily. A 10–20× size increase from JPG to BMP is normal.
Why would I need a BMP instead of a JPG?
Mostly for compatibility with older Windows programs, embedded systems or technical tools that expect a simple, uncompressed bitmap rather than a compressed format like JPEG.
