Reducing the File Size for E-mail

One of Susan's goals is to prevent sending massive e-mails, so it's important to consider the file's size.

To quickly check a document's size, choose File > Document Properties. In the Document Properties dialog, select the Description tab ( Figure 3.14 ). In the Advanced section of the tab, you see details about the document, including its size. Susan's presentation is about 3.2 MB. For recipients with dial-up Internet connections, a file that size could require quite a long download time!


Figure 3.14 Check the size of the finished document in the Advanced section of the Document Properties dialog.

There are two ways you can reduce the file size of a document. One way is through a simple command, the other is through an advanced feature called the PDF Optimizer, which is described in Bonus Chapter 4 on the book's Web site. Here, we'll limit the discussion to the simple method.

Follow these steps to reduce the file size:

  1. Choose File > Reduce File Size to open the Reduce File Size dialog. The default setting for this command is compatibility with Acrobat 5.
  2. Click the "Make compatible with" pull-down arrow to choose another Acrobat version ( Figure 3.15 ).

    Figure 3.15 Choose a version compatibility option in the Reduce File Size dialog.

  3. Click OK to close the dialog. A Save As dialog opens, using the default name of the presentation.
  4. Type a name for the copy and click Save to process and save the file. The copy opens in Acrobat.

Based on the content of the document as well as the compatibility version you choose, you may see a dialog similar to the one shown in Figure 3.16 . In this presentation, for example, there are two issues:

  1. The presentation uses JavaScript to activate the controller and the slide transitions, which may be a problem for viewers using old versions of Acrobat or Acrobat Reader.
  2. The slideshow was created using the Picture Tasks process. As part of the process of reducing file size, images are modified automatically; when Picture Tasks is used to create the slideshow, image optimization is omitted.

Figure 3.16 After the file is processed you may see a Conversion Warnings dialog listing problems or notes about the conversion process.

The original presentation started at a size of more than 3 MB; after reducing the file size using any of the Acrobat 5, Acrobat 6, or Acrobat 7 compatibility settings, it is reduced slightly and decreases download time a bit.
