BMP to JPG Converter — Free & Private
A bitmap is too big to email and nobody needs it lossless. Convert it here — in your browser, with nothing uploaded anywhere.
Why convert BMP to JPG?
Where PNG makes a BMP smaller by packing it better, JPG makes it smaller by discarding what the eye will not miss — and for a photograph the difference is enormous, routinely a hundredfold against the raw bitmap. If the image is going into an email, a listing, a document or a web page, this is the conversion that makes it practical.
The catch worth knowing about
Unlike the PNG route this is lossy, and it is permanent. Keep the BMP if it is the only copy of something that will be edited again; convert to JPG for the version you send out.
One tip before you start
If the bitmap is a screenshot, a scan of text or a diagram, use PNG instead. JPG's compression blurs the sharp edges those images are made of, and it will not even be much smaller — flat colour is the case PNG is good at.

| File size | Very large — no compression at all | Small and adjustable — the baseline everything else is measured against |
| Transparency | No | No — transparency becomes white |
| Where it opens | Universal on Windows; awkward elsewhere | Universal. Nothing has ever refused a JPG |
