Reducing resolution and compressing images in PowerPoint

PowerPoint offers an image compression utility that compresses all of the pictures in the presentation in a single step and reduces their resolution to the amount needed for the type of output you specify (e-mail, Screen, or Print). To reduce resolution and compress images, do the following:

  1. Click a picture, so that the Format tab appears.
  2. Click the Compress Pictures button. The Compress Pictures dialog box appears, as shown in Figure 24-45).
  3. (Optional) If you do not want to compress all of the pictures, mark the Apply to Selected Pictures Only checkbox.

    • Automatically Perform Basic Compression on Save: This automatically compresses any images in your file when you save the file.
    • Delete Cropped Areas of Pictures: This makes any cropping you’ve done permanent.
    • Target Output: Choose a resolution to which you want to reduce the picture(s): Print, Screen, or E-mail.
  5. Click OK to perform the compression.
