Clean Up panel
The options in the Clean Up panel of the PDF Optimizer dialog box allow you to remove useless items from the
document. These items include elements that are obsolete or unnecessary for your intended use of the document.
Removing certain elements can seriously affect the functionality of the PDF. By default, only elements that do not affect
functionality are selected. If you are unsure of the implications of removing other options, use the default selections.
Object Compression Options Specifies how to apply Flate compression in the file.
Use Flate To Encode Streams That Are Not Encoded Applies Flate compression to all streams that aren’t encoded.
In Streams That Use LZW Encoding, Use Flate Instead Applies Flate compression to all content streams and images that
use LZW encoding.
Discard Invalid Bookmarks Removes bookmarks that point to pages in the document that have been deleted.
Discard Invalid Links Removes links that jump to invalid destinations.
Discard Unreferenced Named Destinations Removes named destinations that are not being referenced internally from
within the PDF document. Because this option does not check for links from other PDF files or websites, it does not fit
in some workflows.
Optimize Page Content Converts all end-of-line characters to space characters, which improves Flate compression.
Optimize The PDF For Fast Web View Restructures a PDF document for page-at-a-time downloading (byte-serving)
from web servers.
Enable Fast Web View in a PDF
Fast Web View restructures a PDF document for page-at-a-time downloading (byte-serving) from web servers. With
Fast Web View, the web server sends only the requested page, rather than the entire PDF. This option is especially
important with large documents that can take a long time to download from a server.
Check with your webmaster to make sure that the web server software you use supports page-at-a-time downloading.
To ensure that the PDF documents on your website appear in older browsers, you can also create HTML links (versus
ASP scripts or the POST method) to the PDF documents and use relatively short path names (256 characters or fewer).
Verify that an existing PDF is enabled for Fast Web View
❖ Open the PDF in Acrobat DC, and choose File > Properties. Look in the lower-right area of the Description panel
of the dialog box for the Fast Web View setting (Yes or No).
Verify the Fast Web View Preferences setting
Follow this procedure to make sure that you have Acrobat DC set up to enable Fast Web View during the PDF creation
process.
1 In the Preferences dialog box under Categories, select Documents.
2 On the right side of the dialog box, under Save Settings, make sure that Save As Optimizes For Fast Web View is
selected, and click OK.
Enable Fast Web View for an existing PDF
Use this procedure after you have verified your Fast Web View Preferences setting and checked the PDF properties to
be sure that the file is not already enabled for Fast Web View.
1 Open the PDF.
2 Choose File > Save As. Select the same filename and location.
