Compressing pictures

PowerPoint files can be large and take up a lot of space if the presentation contains a lot of images. This can be a problem when you transmit the file via email or save it on a USB drive. To reduce the file size, you can compress the pictures. Compression is the reduction in file size in order to save space or transmission time.

• Right-click the picture.
• Select Format Picture from the menu. The Format Picture Dialog box will appear.
• Select the Picture tab.
