Quick Overview: PDFix Desktop lets you auto-tag PDFs for accessibility without writing code, using four methods: basic auto-tagging, Preflight-generated templates, AI-generated templates, and pre-defined templates for repetitive layouts. Use basic auto-tagging for one-off files, and a template-based method when you’re processing invoices, statements, or reports at volume.
PDFix Desktop provides a user-friendly interface to auto-tag documents, giving non-developers the ability to improve accessibility in just a few clicks. This article introduces the main auto-tagging methods available in PDFix Desktop. You’ll find tutorials with screenshots, videos, and references to the user guide. By the end, you’ll know how to transform your PDFs into accessible, standards-compliant documents — without writing code.
We selected one of our test files for this demonstration.

Frequently Asked Questions
What is PDF auto-tagging?
Auto-tagging is the process of automatically adding structure tags — paragraphs, headings, lists, tables, and figures — and a reading order to a PDF so it works with screen readers and meets PDF/UA and WCAG accessibility standards.
Can I auto-tag a PDF without writing code?
Yes. PDFix Desktop’s point-and-click interface auto-tags PDFs using basic detection, Preflight-generated templates, AI-generated templates, or pre-defined JSON templates — no programming required. Developers who need code-level or CI/CD integration should use PDFix SDK instead.
How do you auto-tag documents with complex or repeated layouts?
For complex, non-standard layouts, use an AI-generated layout template (via external AI actions like Amazon Textract). For repeated layouts — invoices, bank statements, standardized reports — build a pre-defined JSON template once and reuse it for consistent, predictable tagging across the whole batch.
Is PDFix Desktop or PDFix SDK better for auto-tagging?
PDFix Desktop suits accessibility specialists and non-developers doing visual, batch, or manual-review tagging. PDFix SDK suits developers building auto-tagging into code (Python, C++, Java, .NET) for CI/CD pipelines or processing millions of documents.
Can I integrate PDFix auto-tagging into my existing workflow or CMS?
Yes – with PDFix SDK developers can integrate the same auto-tagging logic directly into workflow pipelines, document management systems, or automated PDF generation processes.
