What Does Conversion to PDF/UA Do?

  • Ensures compliance with PDF/UA (ISO 14289-1).

  • AutoTagging automatically applies structure to meet accessibility guidelines.

  • Embeds fonts and updates metadata for compliance.

What is AutoTagging?

AutoTagging is a feature in the Apryse SDK that automatically detects and applies accessibility tags to a PDF. It eliminates the need for manual intervention, ensuring PDFs are screen-reader-friendly and PDF/UA-compliant.

Important

The AutoTagging feature requires PDFs with extractable text; scanned or image‑only PDFs result in malformed files and missing content. If required glyphs are missing from an embedded font, the system applies font substitution, which may affect visual output but does not fail the operation.

Trial mode page limit

When in trial mode, output is limited to 100 pages, and a random evaluation page is inserted in the output content. Once licensed, there is no page limit and the demo page will no longer be inserted.

How AutoTagging Works

  1. Scans PDFs → Detects headings, lists, tables, images, and links.

  2. Applies appropriate tags → Ensures proper semantic structure.

  3. Maintains document integrity → Keeps formatting unchanged while making content accessible.

  4. Enhances assistive technology support → Ensures compatibility with screen readers.
