When to use this tool
- You need a BMP file because the destination (a website, CMS, app or printer) expects BMP.
- You want uncompressed pixel data that any legacy tool can parse — ideal for legacy Windows software, embedded systems and some scanning pipelines.
- You're moving photos out of JPG into a more widely compatible format.
Best for
- Legacy Windows tools
- Embedded systems
- Software that refuses compressed formats
Every image you drop here is processed entirely inside your browser using the standard Canvas and File APIs. Nothing is uploaded, stored or logged on a server — you can disconnect from the internet after the page loads and the tool still works.
Quality & file size notes
- • BMP is lossless — it preserves the source exactly as it currently is. It cannot recover detail a lossy source has already discarded.
- • Converting a lossy JPG to BMP freezes the image at its current quality — useful for re-editing, but the result will be 2–10× larger.
Things to watch out for
- — BMP files are huge — often 10–30× larger than JPG. Only use it when a legacy tool requires it.

Why convert JPG to BMP?+
BMP offers uncompressed pixel data that any legacy tool can parse, which makes it ideal for legacy Windows software, embedded systems and some scanning pipelines. JPG on the other hand is supported by every browser, app and printer ever made, so converting gives you a file that fits the destination better.
Will I lose quality converting JPG to BMP?+
No — BMP stores the image losslessly. It can't improve on the source, but it won't add any new artefacts either.
