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.

การสนับสนุนทางปฏิบัติ

คําถามก่อนที่คุณดําเนินการ

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.

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.
