Convert BMP to JPG

For photographs, this is the biggest size drop available: uncompressed pixels become a lossy file that's often 95% smaller. For screenshots and line art the artifacts show, and PNG would be the better target.

What is BMP?

The Windows bitmap, which stores pixels raw with no compression worth mentioning. Files are enormous. It survives because it's trivial to read - if you're writing an image loader from scratch or feeding an embedded display, BMP is the format that needs no library.

What is JPG?

JPEG is where photographs live. Its compression is lossy - it throws away detail the eye is bad at noticing, and throws away a bit more every time you re-save - which buys huge size savings on photos and makes a mess of screenshots and text. There's no transparency in it at all.
