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.

理解 PDF Accessibility Preflight 处理之前

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.

什么要审查

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.

常用用

When PDF Accessibility Preflight is useful

Choose the report when you need to answer one of these questions before the next document step.

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.

实用帮助

提问之前,你就开始了

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.
