This is how Accessful works
Accessful audits and remediates PDF documents in four steps: You hand over the document, the AI analyzes the structure and content, adds the missing structural level and delivers an accessible PDF including a audit report - typically in seconds.
Four steps at a glance
-
Submit PDF
Drag-and-drop in the web app or automated via the REST API – individually, as a batch or as a URL list directly from your systems.
-
Analyze document
The AI captures text, layout and image content and finds missing tags, incorrect reading order, missing alt text and unmarked tables and lists.
-
Correct automatically
Accessful supplements the missing structural level directly in the document - the layout and content remain exactly as you handed them over.
-
Result received
You download the accessible PDF according to PDF/UA-2 including an audit-ready report - via the web app or via API.
Transfer PDF: via web app or API
You decide how documents get to Accessful: Using the web app, you drag and drop individual PDFs or entire stacks into the browser. Your systems automatically transfer documents via the REST API – as a file upload or as a URL list. Batch processing also accepts thousands of documents in one go.
- Drag and drop in the web app, without installation
- API upload as a file or via URL list
- Batch processing thousands of documents
- Status can be viewed at any time: Live status in the web app, status query and webhooks via the API
Analysis: The AI understands your document
The AI captures your document as a whole - the text, the layout and the image content, in over 110 languages. From this understanding, she recognizes the barriers that block access for screen reader users:
-
Missing or incorrect tags
Headings, paragraphs and other structural elements that are not suitable for assistive technologies.
-
Incorrect reading order
Content that would be read out in the wrong order – typical in multi-column or complex layouts.
-
Missing alt text
Images, graphics and diagrams without alternative text – otherwise invisible to screen readers.
-
Unexcellent tables and lists
Tables without header assignment and lists that cannot be recognized as a list structure.
Accessful reliably detects typical barriers. The audit report clearly shows criteria that cannot be evaluated automatically.
Remediation: only the structural layer changes
The correction starts exclusively at the structural level - the invisible layer that makes the content accessible to assistive technologies. Accessful adds tags, reading order and alt text.
The visible document remains untouched: after the correction, the layout, text and graphics are exactly the same as before - what your recipients see is the document that you handed over.
- Tags for headings, paragraphs, lists and tables
- Correct reading order, even for complex pages
- Alt text from the visual context
- No change to layout or content
Result: Accessible PDF plus audit report
At the end there is an accessible PDF according to PDF/UA-2, aligned with WCAG 2.2 and EN 301 549. You will also receive an audit-ready report for each document: It records in a comprehensible manner what was checked and corrected - as evidence for internal and external audits.
- Accessible PDF according to PDF/UA-2
- audit-ready report for each document
- Download via the web app or via API
- Results typically in seconds
Two paths, one result
Whether web app or API: analysis, correction and audit report are identical. You choose the path that suits your workflow – or combine both.
-
Web-App
Upload documents via drag-and-drop, track processing in live status, download results and audit reports directly - without installation and without training. Ideal to start straight away.

REST API
Process documents automatically from your systems – from document management, CRM or archive. Webhooks report every processing step back to your application, without any manual intermediate steps.

Where human judgment remains meaningful
Accessful takes the technical hard work off your hands. But two things still belong in your hands:
Editorial releases
You decide whether a remediated document is published. The audit log shows what was changed for each document - the release remains in your process.
Technical context of alt text
The AI describes image content precisely. Your experts are the best judge of whether an alternative text makes the technically intended statement - for example in the case of diagrams with room for interpretation.
To ensure that everything remains efficient, Accessful documents every check and correction step in the check log. This way you can see at a glance where a targeted editorial look is worthwhile - instead of going through every document completely.
Frequently asked questions about how it works
Do I need to prepare my PDFs before uploading them?
No. Accessful works directly on the PDF - you don't need any source files or previous knowledge of PDF/UA. Hand over your documents as they are; AI takes care of analysis and correction.
What happens to scanned documents?
Scanned PDFs without a text layer are initially just images for screen readers. Whether and how such holdings can be processed sensibly depends on the individual case - we can best clarify this using your specific documents Initial consultation.
How do I know what Accessful changed in my document?
Every document receives an audit-ready report. It records in a comprehensible manner what was checked and supplemented at the structural level. The visible layout and content remain unchanged anyway.
Does the correction also work on digitally signed PDFs?
Digital signatures refer to the exact file status - after every subsequent change, even at the structural level, the document must be re-signed. For signed stocks, we recommend following the procedure Initial consultation to clarify, for example by integrating the correction into your process before signing.
