How to Convert JPEG Files to Black & White
JPEG images are created to be at a low resolution to enable users to send and receive the images easily. Color JPEG files can be converted into black and white using a photo-editing program. Adjusting the color option within the program can transform a color JPEG file to black and white without discarding important color information, which might be needed for future projects.

Click and move the slider on the "Saturation" option to the left, until the color in the photo has turned to black and white. Using this option will create what is called a "Non-destructive Edit," meaning that the color information has not been discarded. If the user wishes to undo the black and white adjustment, it can be done by moving the "Saturation" slider to the right.
