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.

步骤2 / 设置和运行

Configure PDF/A Compatibility Preflight

No PDF/A conversion is performed and no archival profile is selected. The operation inspects the supplied file.

理解 PDF/A Compatibility Preflight 处理之前

The processor reads the PDF/A identification namespace in XMP attributes or elements. A document title containing PDF/A is not treated as an identification marker.

什么要审查

Metadata declarations can be incomplete or incorrect. The report does not validate embedded fonts, colour profiles, prohibited features or ISO conformance. Encrypted PDFs must be unlocked before processing.

常用用

When PDF/A Compatibility Preflight is useful

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

01

Inspect an archival export before formal validation.

02

Distinguish a PDF/A title claim from an XMP declaration.

03

Record missing or malformed XMP for a document-support request.

实用帮助

提问之前,你就开始了

Is a PDF/A marker enough for archival acceptance?

No. A marker is a claim inside the file. A dedicated validator must check the complete document against the required PDF/A profile, and your archive may impose additional requirements.

Will this convert an ordinary PDF to PDF/A?

No. It reads metadata and returns a report. Conversion is a separate operation and its output still requires validation before archival acceptance.

What does malformed or unsupported XMP mean?

The metadata could not be safely parsed or exceeded this check's supported limits. It is reported for review rather than treated as a valid declaration or proof that the entire PDF is unusable.

PDF/A Compatibility Preflight: a worked example

XMP declaring part 2 and conformance B is reported as a declaration. A PDF merely titled PDF/A has no marker unless matching identification metadata is present.

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.
