SUMMARY

If you insert a Joint Photographic Experts Group (JPEG) image file into a PowerPoint slide through Microsoft Clip Gallery or Microsoft Photo Editor and save your presentation, the file size is larger than if you import the JPEG image directly into PowerPoint.

If you need to keep the size of your presentation file as small as possible, use the following steps to import JPEG (.jpg) files:
  1. On the Insert menu, point to Picture, and then click From File.
  2. In the Insert Picture dialog box, navigate to the folder that contains the image you want to import.
  3. Click the name of the file you want to import, and then click Insert.

MORE INFORMATION

The data in JPEG files is highly compressed. When you insert a JPEG file by using Clip Gallery or Photo Editor, those programs decompress the data and send the picture information to PowerPoint without the data compression.

PowerPoint itself understands the JPEG family of compression schemes, and can import the picture without decompressing it.

If you have already inserted a JPEG file as a Clip Gallery object or as a Photo Editor object, you can reduce the size of the file somewhat by doing the following:
  1. Click the image on your slide.
  2. On the Edit menu, click Cut.
  3. On the Edit menu, click Paste Special.
  4. Click Picture or Picture (Enhanced Metafile) on the As list.
PowerPoint applies data compression to inserted pictures. However, the data compression scheme it uses does not reduce the file size as much as the JPEG data compression schemes.

NOTE: JPEG compression sacrifices picture quality. The data compression PowerPoint uses does not.
