01
Inspect the PDF structure
EasyPDFUA reads tags, ParentTree, document title, language, links, fonts and Unicode mappings. More on PDF/UA checks
Check PDF/UA and tag existing PDFs
Check PDFs for accessibility and tag them retroactively.
EasyPDFUA reads the existing PDF structure and checks document title, language, links and fonts, among other things. Where a change is technically unambiguous, the application creates a new tagged PDF for download.
Features
What EasyPDFUA checks in a PDF.
02
Tag existing PDFs
The application only applies technically verifiable changes and writes them to a new PDF copy. More on tagging
03
Read the report
The report shows the structure tree, detected problems, warnings and the limits of automated checking. Common errors
Retroactive tagging
Improve existing PDFs after the fact.
EasyPDFUA works with PDF files that already exist. The original is preserved; a tagging result is provided as a new file.
- 1
Select a PDF
Up to 5 MB on the free plan, up to 50 MB per file with Premium.
- 2
Inspect or run tagging
Risky, signed, encrypted or technically ambiguous documents may be rejected.
- 3
Validate the result externally
Retroactive tagging can be incomplete or fail. An additional check, for example with PAC or veraPDF, plus a manual review is strongly recommended. An EasyPDFUA report and a generated copy are not a guarantee or certification of full PDF/UA conformance.

FAQ
Frequently asked questions
What does EasyPDFUA do?
EasyPDFUA reads the existing structure of a PDF, checks document title, language, tags, links, fonts and Unicode mappings, and – where a change is technically unambiguous – creates a new tagged copy of the PDF.
Is EasyPDFUA free?
Yes. The free plan lets you analyse and tag PDFs up to 5 MB, up to 10 documents per day, without payment details. Premium processes files up to 50 MB, has no daily limit and includes API access.
Is the result certified as PDF/UA compliant?
No. Retroactive tagging can be incomplete. An EasyPDFUA report or generated copy is not a guarantee or certification of full PDF/UA conformance. We recommend checking the result with PAC or veraPDF and a manual review.
Does EasyPDFUA add headings, alt text and table structure?
No. The tagger creates a conservative base structure and fixes metadata, language, link tags, tab order and Unicode mappings. Headings, lists, tables and alternative text for images still need manual work or an accessible export from the source document.
What happens to my original PDF?
The original is never overwritten. Tagging always produces a new copy, which can be downloaded once within 15 minutes. PDF contents are not sent to external processing services.
Which PDFs are rejected?
Encrypted, digitally signed or technically ambiguous PDFs may be rejected, because any change could invalidate a signature or damage the content.
