302 ADOBE ACROBAT 3D VERSION 8
User Guide
Depending on the complexity of the web page, you may need to do extensive repairs by using the TouchUp Reading
Order tool or editing the tag tree in Acrobat.
To produce the most accessible PDFs from web pages you create, first establish a logical reading order in their HTML
code. For best results, employ the Web Content Accessibility Guidelines that are published by the World Wide Web
Consortium (W3C). The guidelines are available on the W3C website at www.w3.org.
1 Choose File > Create PDF > From Web Page.
2 For URL, type the address of the web page, or navigate to the web page location.
3 Click Settings.
4 In the General tab, select Create PDF Tags, and then click OK.
5 Select any other options as appropriate, and then click Create.
Creating a tagged PDF from an authoring application
In most cases, you create tagged PDFs from within an authoring application, such as Adobe FrameMaker®, Adobe
InDesign, or Microsoft Word. Creating tags in the authoring application generally provides better results than
adding tags in Acrobat.
PDFMaker provides conversion settings that let you create tagged PDFs in Microsoft Excel, PowerPoint, and Word.
For an in-depth guide to creating accessible PDFs, visit the accessibility page of the Adobe website.
For more information, see the documentation for your authoring application.
About tags in combined PDFs
You can combine multiple files from different applications in one operation to create a single PDF. For example, you
can combine word-processing files with slide presentations, spreadsheets, and web pages.
During conversion, Acrobat opens each authoring application, creates a tagged PDF, and assembles these PDFs into
a single tagged PDF.
The conversion process doesn’t always correctly interpret the document structure for the combined PDF, because the
files being assembled often use different formats. Because you may need to modify the reading order and tag tree of
the combined document, you may need to use Acrobat Professional or Acrobat 3D to create an accessible PDF from
multiple documents.
When you combine multiple PDFs into one tagged PDF, start with all untagged PDFs or all tagged PDFs. Combining
tagged and untagged PDFs results in a partially tagged PDF that isn’t accessible to people with disabilities; some
users—such as those using screen readers—will be completely unaware of the pages that don’t have tags. If you start
with a mix of tagged and untagged PDFs, tag the untagged files before proceeding. If the PDFs are all untagged, add
tags to the combined PDF after you finish inserting, replacing, and deleting pages.
Keep in mind that when you insert, replace, or delete pages, Acrobat accepts existing tags into the tag tree of the
consolidated PDF in the following manner:
• When you insert pages into a PDF, Acrobat adds the tags (if any) for the new pages to the end of the tag tree, even
if you insert the new pages at the beginning or the middle of the document.
• When you replace pages in a PDF, Acrobat adds the tags (if any) from the incoming pages to the end of the tag
tree, even if you replace pages at the beginning or the middle of the document. Acrobat retains the tags (if any) for
the replaced pages.
