How do you convert a .bmp image to a .jpg image?

Factual Questions
1

I am clueless. I want to upload a picture onto the 'net, but the site says it is not a valid image, it needs to be in .jpg format. Any advice?

2

Use a program such as Gimp. Probably there are lots of other utilities that can do the same thing.

3

MS Paint that comes with Windows will do it.

Open the .BMP with Paint, then “Save As” .JPG.
