Certified PDF

What this checks

The PDF is read in your browser, its text is extracted, and the hash is compared with the value stored in the file metadata.

What this verification means.

This check confirms file integrity only.

  • It is not a legal certification.

    A matching hash shows that the PDF still matches its certified state. It does not confirm legal validity or translation quality.

  • The verification data is inside the PDF.

    Anyone with the file can inspect the metadata and recompute the same hash locally.

  • There is no external certificate registry.

    DocTranslate AI does not maintain a public database of issued certificates.

  • Any PDF edit should break the match.

    Re-saving, changing text, or altering the certification page can invalidate the embedded hash. That is the intended behavior.

What this page still cannot prove.

A successful integrity check is useful, but it should not be stretched beyond that purpose.

This page does not prove that the original source document was genuine, that the translation was accurate, or that the PDF carries legal weight in any jurisdiction.

It only proves that the current file still matches the certified state encoded into that PDF by this product.

If you need legal validation or professional assurance, this integrity check should be treated as supporting technical evidence, not as a substitute for formal review.

Verification FAQ.

Short answers about what this PDF check does and does not establish.

What exactly does this page verify?

It verifies whether the current PDF still matches the integrity data embedded into that certified PDF by this product.

Does a successful match prove legal validity or translation quality?

No. A successful match proves file integrity only. It does not prove legal validity, source authenticity, or translation quality.

Why does any PDF edit break the match?

That is the intended behavior. If the translated content no longer matches the certified state, the recomputed hash should no longer match the embedded hash.

Is there a public certificate registry?

No. Verification on this site is file-based. It reads the PDF, inspects the embedded metadata, and recomputes the hash locally in the browser.
