Choose one unlocked PDF. The source remains unchanged and the result downloads separately.

Selecting a PDF sends it to the API for inspection. Running the report sends it again for processing. These requests use memory and do not create a server-side file history.

Step 2 / configure and run

No accessibility target or certification level is selected. This report records limited observable signals.

Product contract

Understand PDF Accessibility Preflight before processing

Language is read from the PDF catalogue Lang entry, not inferred from the text or PDF version. Each page is checked for extractable text and link annotations.

01

What you provide

One unlocked PDF, up to 10 MB and 500 pages. Only upload a document you are authorised to process.

02

What you receive

A JSON report with title and language presence, declared language, page text counts and link counts.

03

What to review

This is not a WCAG or PDF/UA conformance test. It does not validate tags, reading order, alternative text, contrast, form labels or screen-reader usability. A language declaration may also be wrong.

Common uses

01

Identify missing title or language metadata.

02

Find image-only pages needing a text-layer review.

03

Prepare a short findings file for an accessibility specialist.

Practical help

Questions before you run it

Can this certify that my PDF is accessible?

No. These checks are only a starting point. An accessibility review must also inspect document structure, reading order, meaningful alternatives, interactive controls and the experience with assistive technology.

Does it detect the language of the text?

No. It reads the declared PDF document language. A missing declaration is reported as missing, while an existing declaration still needs review against the actual content.

Will it add tags or repair the document?

No. The operation returns findings only. It does not edit metadata, add a text layer or repair the accessibility structure of your original PDF.

Document workflow

PDF Accessibility Preflight: a worked example

A PDF with a title but no catalogue language reports title_present as true and language_present as false. A scanned page may report no text even when its image looks readable.

Keep the downloaded report beside the exact PDF you checked. If the document changes, run it again; the previous findings describe the earlier file, not the replacement.
