Making a PDF accessible doesn’t have to be complicated or time-consuming. Whether you’re meeting PDF/UA compliance requirements, following WCAG guidelines, or simply ensuring your content is usable by everyone, PDFix Desktop makes the process fast and stress-free. In this guide, you’ll learn how to turn any PDF into a fully accessible, screen-reader-friendly document in just a few minutes — even if you’ve never done accessibility work before.
Why PDF/UA and WCAG Compliance Matters for Accessible PDFs
If your PDF isn’t accessible, you’re excluding millions of people who rely on assistive technologies like screen readers.
Beyond the human impact, inaccessible PDFs can put you at legal risk under standards such as:
- PDF/UA (ISO 14289)
- WCAG
- European Accessibility Act
- Section 508
- Americans with Disabilities Act (ADA)
The challenge? Most PDF accessibility workflows are time-consuming, technical, and error-prone requiring you to manually tag every heading, table, and image.
The Fastest Way to Make a PDF Accessible with PDFix
PDFix Desktop removes the complexity with AI-powered auto-tagging and smart editing tools that let you create PDF/UA-compliant PDFs in minutes.
Whether your PDF is completely untagged or partially accessible, PDFix provides:
- One-click Make Accessible pipeline
- Automated document structure recognition
- Validation tools to check PDF/UA compliance
- Auto and semi-auto fixes for common accessibility issues
- Easy manual editing when needed
The accuracy of the automatically detected tag structure depends on the complexity of the document layout. To improve the quality of the tagging process, you can customize detection settings in the Template Side Panel. Templates let you define specific recognition rules for headings, tables, figures, and reading order — ensuring consistent, high-accuracy results even in complex or non-standard layouts.
Using Auto-Tag PDF for Accessibility
PDF/UA requirement: A complete tag tree that reflects the logical reading order. Every meaningful element — headings, paragraphs, lists, tables, figures — must be tagged. Decorative elements must be marked as artifacts.
- PDFix Desktop can automatically tag it using the Accessibility -> Auto-Tag action
- PDFix analyzes the layout, identifies headings, paragraphs, and other structures, then creates a complete, semantic tag tree
- Decorative content is detected and marked as artifacts.

Use the “Make Accessible” Command
The Make Accessible action is a pre-built accessibility pipeline in PDFix Desktop. It not only tags the document but also performs all essential steps to meet PDF/UA requirements.
This includes:
- Clearing document structure
- Auto-tag
- Set Language and Title
- Create Bookmarks
- Embed Fonts
- Fixing common accessibility issues
- Set PDF/UA Standard
Validate with the PDF Accessibility Checker
Once your PDF is tagged, the next step is to verify it meets PDF/UA accessibility standards. PDFix Desktop includes a built-in PDF Accessibility Checker — a fast, accurate tool to ensure your document passes compliance checks and is usable for assistive technology.
How to Validate Your PDF in PDFix Desktop:
- Open your document in PDFix Desktop.
- In document view, go to the Validation Side Panel.
- Click Validate to check against PDF/UA-1 standards, or choose Validate With to apply a specific validation profile.
Fix PDF Accessibility Issues in Seconds
After running validation, any detected issues will be listed with clear descriptions.
PDFix offers multiple ways to fix them:
- Auto-Fix – Instantly corrects the most common accessibility problems in one click.
- Quick Fix – Provides targeted commands to address specific issues without editing the entire file.
- Manual Fix – For complex issues, use the Tag Tree, Bookmarks, Content, or Annotations panels to make precise corrections.
Create a Screen Reader Friendly PDF
Always revalidate after fixes to confirm compliance. When all errors are resolved, the checker will confirm your PDF has successfully passed PDF/UA validation. At this point, your file is fully accessible and compliant with industry standards — ready for distribution without legal or usability risks.

Frequently Asked Questions
How do I make a PDF PDF/UA-compliant fast?
Open the PDF in PDFix Desktop. Go to Actions → Make Accessible (includes Auto-Tag, sets Language & Title, creates Bookmarks, embeds Fonts for PDF/UA compliance). Open the Validation side panel and click Validate (PDF/UA-1). Apply Auto-Fix or Quick Fix, use manual edits if needed, then validate again until status is Passed.
What does the Make Accessible command actually do?
Make Accessible is an automated one-click workflow that clears old structure, runs Auto-Tag (or Auto-Tag with Paddle AI), sets Document Language and Title, creates Bookmarks, embeds Fonts, and prepares the file for PDF/UA validation and fixes.
Should I use Auto-Tag or Make Accessible?
Auto-Tag quickly builds a semantic tag tree. Make Accessible runs Auto-Tag plus key metadata and font embedding steps — making it the best starting point for fast PDF/UA results.
How do templates improve accuracy?
In the Template side panel you can define rules for headings, tables, figures, reading order, and artifacts. Templates standardize recognition and boost accuracy on complex layouts. Use them to fine-tune detection when Auto-Tag alone isn’t perfect.
How do I validate PDF/UA in PDFix?
Open the Validation side panel. Click Validate (PDF/UA-1) or Validate With to select a profile. Review results, apply Auto-Fix or Quick Fix, and re-validate until Passed.
Does PDFix include an AI model for layout recognition and auto-tagging?
Yes. In the document view, choose Run Action → Accessibility → AutoTag( Paddle), or AutoTag(AmazonTextract) to try an alternative AI-powered engine that can improve detection on certain layouts. We’re constantly adding new models, which you can find in our marketplace.
What’s the fastest way to fix common issues?
Auto-Fix provides one-click repairs for frequent problems. Quick Fix offers targeted commands for specific issues such as missing language or bad list structure. Manual Fix can be used for complex issues via the Tag Tree, Bookmarks, Content, or Annotations panels.
How do I ensure the reading order is correct?
After Auto-Tag or Make Accessible, open the Tag Tree and Content panels to verify order from top to bottom. You can even convert PDFs to HTML to preview the reflowable layout and verify the correct reading order.
How are decorative elements handled?
PDFix detects many decorative items and marks them as artifacts automatically. If something is missed, select the object in the Content panel and mark it as Artifact.
How do I add alt text to images or figures?
If an image is decorative, mark it as an Artifact instead of adding alt text. In the Tag Tree, select the Figure tag and add concise, meaningful Alt text. You can also run an action to automatically add alt text to images using PDFix, OpenAI, or Saleforce BLIP. We’re constantly adding new models, which you can find in our marketplace.
