Understanding the Compress Pictures dialog box in Publisher

If you'd like to control how you compress your pictures, you can use the Compress Pictures dialog box in Publisher.

Compress picture dialog box.

Notes   

  • GIF files cannot be significantly compressed further.

  • An object inserted by using the Object command on the Insert menu cannot be compressed, because it is inserted as an object and not as a picture.

Compression savings

Current combined image size     Displays the current combined size of all pictures in the publication.

Estimated combined image size after compression     Displays the estimated combined size of all pictures in the publication after compression. (This value changes depending on other options that you select.)

Compression options

Delete cropped areas of pictures     Select this check box to delete the pixel information that's normally stored for cropped areas of pictures. (The info associated with cropped areas isn't visible or used.)

Remove OLE data     Select this check box to remove the 24-bit uncompressed bitmap that is part of a picture's OLE stream. The small viewable image that is part of the OLE stream is deleted, but the picture itself appears the same. (After you remove the OLE data from a picture, you won't be able to open that picture with the app originally used to create the picture.)

Resample pictures     Select this check box to make a resized picture smaller by deleting the residual data from the picture's original size. (If a picture is resampled, and then stretched larger than the size rate at which it was resampled, the picture quality is reduced.)

Convert to JPEG where appropriate     Select this check box to convert the picture to a JPEG file.

Notes   

  • Depending on the nature of the picture — for example, whether it's a photo, how much noise or spiking is in the picture's histogram, and so on — the level of compression varies. The compression level of PNG pictures can't be modified.

  • Pictures 100 KB or less are not compressed.
