1. What Types of PDFs can be converted

The PDF2ePub solution allows you to convert all types of PDFs, with the exception of PDFs that have "Content Copying" permission turned off. If the document is not a Tagged PDF, then "Changing the Document" permission should also be turned on for the tool to work. The tool works best with Tagged PDFs . Tags withing PDFs define the logical structure of the content and contain information necessary for content repurposing, reflow, and accessibility.

Converting a Tagged PDF

You can check if the PDF is Tagged by selecting File > Properties and looking at the "Tagged PDF" value under the Advanced section. For best conversion results, tag a document when converting it to PDF from an authoring application. Examples of these applications include Adobe FrameMaker®, Adobe InDesign®, Microsoft Word®, or OpenOffice Writer. A good primer on creating Tagged PDFs is available here by Adobe. The instructions for using Microsoft Word to create Tagged PDFs is available here .

Converting an untagged PDF

For untagged PDFs, PDF2ePub solution uses Acrobat's inbuilt facility to create tags. While the feature adequately tags most standard layouts, it cannot always correctly interpret the structure and reading order of complex page elements. These elements include closely spaced columns, irregular text alignment, nonfillable form fields, lists, and tables that don't have borders. These issues cause problems in the converted document. It is highly recommended that you use the ePub Tool and the TouchUp Reading Order tool, both described later in help, to check and fix any reading order or logical structure issues in the document before starting the conversion process.

2. How to convert a PDF to ePub document

Converting a PDF to ePub document is as simple as opening the PDF in Adobe Acrobat, choosing File > Save As, and then selecting "IDPF ePub (*.epub)" option from the drop down menu. For most simple layout PDFs, this step is sufficient. However, for converting PDFs with complex layouts, it is recommended that you follow the instructions below for best results from the conversion process.

Summary of steps

  1. Open the PDF document in Adobe Acrobat
  2. Use the ePub tool to select areas on any page and mark the selection as background so that content within selection is excluded from conversion. This is most useful for excluding headers, footers, and other running elements.
  3. If your document has complex layout or uses Lists or Tables, use the TouchUp Reading Order tool to make sure the content is tagged properly on each page
  4. If necessary, add bookmarks which get converted to Table of Contents in ePub document.
  5. Go to File > Save As and choose "IDPF ePub (*.epub)" from the drop-down to start the conversion.

Detailed steps

Using the ePub tool

  1. The PDF2ePub plugin adds epub Tool to Acrobat's toolbar. The epub Tool can be found next to the Hand and Marquee Zoom tools on the toolbar. The highlighted area in Red in the image shows the epub Tool.
  2. Click on the epub tool to activate it. If the PDF document is not Tagged, the epub Tool will show you the following message before using generating tags for the PDF. After the tags have been added, you can save the PDF document to retain the tags.
  3. The tagging process produces a summary of results as shown in the image below containing a list of problems found and suggestions on how to fix the problem. The tagging issues can be addressed using the Tags panel, avaiable via View > Navigation Panel > Tags or by using the TouchUp Reading Order tool explained later in this document.
  4. After the tags have been added to the document, you can drag and select any area on the PDF page. The selected rectangular area can be adjusted by clicking and dragging the handles shown at the selection's corners.
  5. Once you have selected the exact area to mark as background, bring up the context menu through right-click of mouse. The image below shows the context menu. The two options available to you are:
    • Set area as background on This Page. This option marks the selected area as background on the current page on which you have made the selection. This is useful for content that does not appear on every page but you would like to exclude it from conversion.
    • Set area as background on All Pages. This option marks all content within the selected area as background on all pages of the PDF document. This is useful for cases when you have a running header, footer, or any watermark that you would like to exclude from conversion. You can use the epub Tool as many times as you would like before starting the conversion process.

Using the TouchUp Reading Order tool

Once you are finished using ePub tool to mark headers, footers, and other such constructs as backgroud, the next step is to examine the structure on individual pages using the TouchUp Reading Order tool and fix any tagging issues. This step is highly recommended for PDFs with complex layout including constructs such as closely spaced columns, tables, and lists.
  1. TouchUp Reading Order Tool is available via Tools > Advanced Editing > TouchUp Reading Order Tool. If you have an untagged document, you will need to first make it tagged by selecting Advanced > Accessibility > Add Tags to Document (however, you can skip this step if you have used the ePub tool on the document before using the TouchUp tool). Here is what the TouchUp Reading Tool panel looks like.
  2. The TouchUp Reading Order Tool divides a tagged page into shaded segments. Each segment is numbered indicating the read order of the item on the page. You can also verify the read order of items on the page by displaying the order panel from the TouchUp Reading Order Tool.If the reading order as indicated by the numbered sequence of elements in the page view and items in the order panel is not satisifactory, you can change the sequence of items in the Order Panel to reflect the proper reading sequence for the page by sliding Order Panel items up or down into their proper sequences. For more information on using TouchUp Reading Order Tool, see step 7 of Creating Accessible PDFs Using Adobe Acrobat. or the Acorbat help documentation .

Adding Bookmarks

The PDF2ePub solution converts all PDF bookmarks to Table of Contents in ePub document via NCX document. If the PDF document does not have any bookmarks, follow one of the two options listed below to add desired bookmarks which will become part of Table of contents in the converted ePub document.
  1. Open the Bookmarks panel through View > Navigation Panel > Bookmarks. From the drop-down at the top, select New Bookmarks from Structure . You will see a dialog box prompting you to select the tags that you want to use for bookmarks. Based on the contents of your document, select appropriate tags. In most cases selecting H1 and H2 should be fine. OR
  2. Open the Bookmarks panel through View > Navigation Panel > Bookmarks. First go to the page or view that you would like to bookmark. Choose New Bookmark from the Document or Setting menu on the Bookmark Panel. Click the new untitled bookmark and enter the desired name for it. After you have several bookmarks created, you can create a hierarchy amongst the bookmarks by simply dragging and dropping them in the desired place. For more details see this Adobe Press article on creating bookmarks in Acrobat.
