What is the procedure for changing a received (via e-mail) "bmp" photo into a "jpg" one?

Asked by JackAdams (6536points) September 2nd, 2008

I think “bitmap” or “bmp” photos suck, and I want to change the ones I have, to “jpegs” or “jpgs,” and I’d appreciate having step-by-step instructions on how to do that, on my Windows XP/Home Edition computer.

I do it in Paint. Open it in Paint. Save as a JPEG.

Hmm.. on my computer I just have to change the .bmp in the name to a .jpg and a little box pops up asking me if I really want to change it. I click yes and it switches it for me.

@Allie… that only changes the name of the file… not its contents. Since either one of those are defaulted for opening by your image viewer, your viewer then looks at the contents to determine the actual kind of information therein. Hence there’s likely no obvious drawback to your approach, other than it’s logically wrong.

Bitmap (.bmp) images are not compressed, and in that way are superior to JPG images.

JPEG (.jpg) images use a lossy compression algorithm. You can control the level of compression, and hence picture quality. JPG image files are typically much smaller than BMP image files, and the quality is still acceptable enough for printing.

@Marina: Thanks!

The “paint” option seems to work for me.

Where do I mail your money order?

Rob: Oh.. I’m not very tech savvy. I should stay away from these kind of questions I guess. =(
