With available mainstream programs in the fields of word processing,
desktop publishing or PDF editing it is not possible to implement
lean PDF accessibility workflows. axesPDF fills this gap.
axesPDF is for all accessible PDFs (and Workflows)
- you need it especially for accessible PDF documents created
with Adobe Indesign or Acrobat.
No matter if you create an accessible PDF to be published with
Adobe InDesign, Acrobat or MS Word, axesPDF® is a short cut
if you want to achieve PDF/UA conformance.
Important.
Precondition for working with axesPDF is that
your PDF document has already a tag structure.
If this is not the case then first create a PDF with tags,
either from converting the source document or
with a PDF editor.
axesPDF as short cut
The checking & remediation tool axesPDF helps accessible
document authors reaching fully PDF/UA compliant documents with ease.
You can use it at the end of your InDesign, Acrobat or Word workflow.
Usually you start with the PDF/UA check.
Then you look at the errors, choose the corresponding commands and fix them
- in most cases only with one click.
If you have tagged PDFs but you need to remediate fonts, spacing,
structural tags tree errors or have lots of complex tables,
axesPDF is the tool for you.

1-click-fixing buttons
- axesPDF® offers a lot of 1-click-fixing buttons like:

- Add IDs to every Note-Tags
- Add link descriptions

Complete PDF/UA-check - automated & human
Some PDF/UA requirements can be checked by a machine.
But there are also requirements that have to be checked by a human.
Therefore both is necessary:
an automated PDF/UA-check and an additional visual evaluation of the PDF.
- All machine-checkable checkpoints
In axesPDF® an automated PDF/UA-check (Tab Checker) is included.
It covers all machine-checkable checkpoints of the Matterhorn Protocol.
- Tools for the visual evaluation
For the additional visual evaluation - essential part of every PDF/UA-check -
there are two complementary tools in axesPDF®:
- Ribbon tab: Preview:
- a simplified structure view for a quick visual evaluation
(for example: evaluation of the semantics)
- Ribbon Tab: Logical Structure Tree:
- an expert view of the Logical Document Structure for a
specific diagnosis and check of the logical order in
combination with a parallel document view.
Interactive report of all PDF/UA issues with help how to fix it
Diagnosis made easy: Clickable issues in the accessibility report lead
directly to the corresponding locations in the document view and
in the Logical Structure Tree.
By using the F1-key you can get useful hints,
how to fix a specific PDF/UA issue.
Fixing PDF/UA issues - in many cases by using 1-click-fixing buttons
What is the use of a detailed accessibility report anyhow,
if the fixing of the issues is much to time-consuming or complicated
- at least for an average user?
For such cases axesPDF® offers a lot of 1-click-fixing buttons
like for example:
- Add PDF/UA identifier
- Reset Zooms
- Set Contents key of Link annotations
- Set Tab Order
If you cannot fix the issue with one click,
you find task panes in axesPDF®,
that help you to fix the issue - like for example:
- Add Bookmarks
- Create Destinations
- Fix Roles
- Insert Spaces
- Remove Language Assignments
- Rename Tag
