Frequently Asked Questions
What does auto-tagging a PDF mean?
Auto-tagging adds invisible structure tags to your PDF (like headings, lists, tables, and images) so that assistive technologies – such as screen readers – can interpret and navigate the content correctly. PDFix Desktop automates this process, saving hours of manual tagging.
What is the best way to auto-tag a PDF for accessibility?
The best method depends on your document type:
- Basic Auto-Tagging – ideal for quick fixes and mixed layouts.
- Preflight Auto-Tagging – detects document structure automatically.
- AI-Generated Templates – best for complex or variable layouts.
- Pre-Defined Templates – perfect for repetitive files like invoices or reports.
How accurate is AI auto-tagging for PDFs?
AI auto-tagging with PDFix Desktop is highly accurate for complex layouts, as it uses machine-learning models (e.g., Amazon Textract) to recognize structure and generate templates automatically. You can review and refine tags afterward to achieve 100% compliance.
Can I batch auto-tag multiple PDFs at once?
Yes. PDFix Desktop supports batch auto-tagging, allowing you to process entire folders or document sets simultaneously. This is ideal for organizations managing large archives, ensuring all PDFs meet accessibility standards efficiently.
Do I need coding skills to auto-tag PDFs in PDFix Desktop?
No coding skills are required. PDFix Desktop provides a visual, drag-and-drop interface with automated tagging options. You can create or import layout templates without writing code, making it suitable for accessibility specialists, designers, and non-developers.
Can I integrate PDFix auto-tagging into my existing workflow or CMS?
Yes. PDFix offers both Desktop and SDK solutions, so developers can integrate the same auto-tagging logic directly into workflow pipelines, document management systems, or automated PDF generation processes.
How can I generate a manual layout template for auto-tagging complex PDF structures in batch?
You can create a manual layout template in a JSON file that defines how PDFix should recognize elements such as tables, headers, and anchors across pages. If you have programming or technical skills, you can build the template yourself by following our Layout Template Guide.
Otherwise, simply send us a sample document, and our team can create a custom template for you so you can apply it and see exactly how it works and review the output results before scaling it for batch auto-tagging.
