PDF Accessibility Remediation for Multilingual Documents
For many organisations, PDF accessibility is no longer optional. Since 28 June 2025, the European Accessibility Act has required businesses offering certain products and services in the EU to make them accessible, and that can include the PDFs those services rely on. For companies working with multilingual content, this adds a layer of complexity that most general accessibility providers are not equipped to handle.
This article explains what PDF remediation means, what the process looks like in practice, and why multilingual documents in particular need specialist support. If you already have documents that need fixing, see the PDF accessibility remediation service for scope, process and deliverables.
The complete PDF Accessibility Guide covers everything from tags and alt text to WCAG and legal requirements, in plain language anyone can understand. Free and open.
What is PDF remediation?
PDF remediation is the process of modifying an existing PDF document so that it can be read and navigated by assistive technologies, most commonly screen readers used by people who are blind or have low vision.
A standard PDF exported from InDesign, Word, or another design tool is often visually polished but structurally invisible to assistive technology. The software sees text and shapes on a page, not a structured document. Remediation adds the structure that was missing.
Tagging
Adding structural tags that define headings, paragraphs, lists, tables, and images so screen readers can interpret them correctly.
Reading order
Ensuring the logical reading sequence matches the visual layout, which is critical in multi-column designs, sidebars, and footnotes.
Alternative text
Writing descriptive alt text for all images, charts, and non-text elements so screen readers can describe them accurately.
Document metadata
Setting the document title, language, and other properties required by PDF/UA and WCAG.
Forms and links
Making interactive elements keyboard-navigable and properly labelled so they work without a mouse.
A properly remediated PDF can be validated against PDF/UA and checked against WCAG 2.1 AA. That is the technical basis organisations use to meet accessibility obligations such as the European Accessibility Act.
Why the European Accessibility Act changes everything
The European Accessibility Act has applied since 28 June 2025. It covers specific products and services, including e-commerce, consumer banking, e-books, electronic communications and certain passenger transport services, and it requires the information those services provide to be accessible, which often includes documents published online. Microenterprises providing services are exempt, and public sector bodies were already covered separately by the Web Accessibility Directive. Publishers, financial services and any company distributing product manuals, reports, or catalogues digitally should check whether their documents fall within scope.

Enforcement is handled nationally: market surveillance authorities can require corrections, and member states set the penalties. For translation agencies whose clients fall under the Act, the final deliverable is no longer just a translated, layout-accurate PDF. It must also be an accessible one. Whether a specific document is in scope is a legal question for the organisation publishing it.
The special challenge of multilingual PDF accessibility
Most discussions of PDF remediation focus on single-language documents. But multilingual projects introduce complications that standard accessibility workflows are not designed for.
Language tagging must match the target language
Each language version requires its own language metadata, and passages in another language need their own language tags. When a screen reader encounters a German document tagged as English, it mispronounces the text, making the document unusable even if it is otherwise well-structured.
Right-to-left languages need their own verification
Arabic, Hebrew, Farsi and Urdu versions need their reading order, language tags and extracted text checked separately. Some failures, such as a wrong document language written during export or a broken text layer, pass automated validation and only show up in screen reader testing.
Fonts must map correctly to Unicode
A PDF can look perfect while its text layer is broken. If a font's glyphs lose their Unicode mapping, screen readers skip or misread content, and automated checkers often do not notice. Font choice, and sometimes the exact font version, must be verified at the remediation stage.
Alt text must be translated
Images carry alt text in a specific language. In a 25-language project, that means 25 separate alt text sets, each accurate, contextually appropriate, and written or reviewed by someone who knows the target language.
These are not edge cases. They are standard challenges in any large-scale multilingual DTP project, and they require a specialist who understands both accessibility and multilingual document production.
Need your PDFs made accessible?
PDFs remediated to PDF/UA-1 and WCAG 2.1 AA, including multilingual documents with right-to-left and CJK scripts. Every file is validated with PAC 2026, tested with the NVDA screen reader and delivered with a remediation report.

How the PDF remediation process works in practice
In a typical multilingual DTP workflow, remediation is the final step before delivery, but it must be planned from the beginning.
The remediation workflow
- Source file quality matters. A well-structured InDesign file using proper paragraph styles and master pages produces a cleaner exported PDF and significantly reduces remediation time.
- Export settings must be correct. The PDF must be exported with tagging enabled. In Adobe InDesign, this means using the correct export preset and enabling accessibility options before the file leaves the design environment.
- Remediation is performed in Adobe Acrobat Pro. Tags, reading order, alt text and language settings are corrected manually. Automated tagging tools provide a starting point, but manual review is always required.
- Validation and screen reader testing. The remediated PDF is validated with PAC 2026 against PDF/UA, then tested with the NVDA screen reader to confirm that the reading experience matches the intended document structure. Validation alone is not enough, because some failures only become audible.
- Each language version is handled separately. There is no shortcut. A 20-language project requires 20 individually remediated PDFs, each verified for its specific language, reading direction, and character support.
Who needs PDF remediation services?
Remediation is likely to be relevant to your organisation if you:
- Publish PDFs on a website accessible to EU users
- Distribute product manuals, financial reports, or catalogues digitally
- Work with translation agencies to produce multilingual document packages
- Need PDFs that meet WCAG 2.1 AA or PDF/UA, or that support European Accessibility Act obligations
- Have existing PDF archives produced before accessibility requirements applied
- Receive translated InDesign or IDML files that need to be exported and prepared for distribution
If your clients are asking for accessible PDFs as part of the final deliverable, this is a service that must be built into the project workflow, not added as an afterthought.
Accessible PDFs from the start
The most cost-effective approach to PDF accessibility is to build it into the document design process. When InDesign files are structured correctly from the beginning, using paragraph styles, proper heading hierarchies, and correctly prepared image frames, the exported PDF requires far less remediation.
In multilingual DTP projects, this means coordinating accessibility requirements between the designer, the DTP specialist, and the translator team before the first IDML file is exported. Fixing accessibility issues upstream saves significant time and cost at the remediation stage.
PDF remediation makes documents accessible to people using assistive technologies, and for many organisations in the EU it is now required. For multilingual documents, the process is significantly more complex than for single-language PDFs, requiring language-specific tagging, separate verification of right-to-left versions, translated alt text, and individual testing for each language version.
