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.

Понимать PDF/A Compatibility Preflight Перед обработкой

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.

Практическая помощь

Вопросы перед тем, как вы их задаете

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.
