FAQ

Can I see or download my original PDF from the results page?

No. You cannot view or download your original PDF from the results page. The page shows only the analysis metadata and findings, not the document itself.

Why the original is not there

This is deliberate. The results page never exposes the original document, so nobody who holds a shared result link can retrieve the underlying PDF, even if the link is passed on. Where a web-uploaded file is retained, it is used only in anonymised form to improve the detection algorithm, as described in the privacy policy. Files submitted through the API are not stored.

What the page does show

  • The verdict: Intact, Modified or Inconclusive, and the reason when it is inconclusive.
  • The named findings behind a modified verdict.
  • Metadata: creation date, modification date, creator and producer.
  • Structural information, such as signatures and the page count.
  • The file name, file size and the date of the check.

Where to find your results later

Signed in, your checks are listed in the dashboard. Through the API, call GET /v1/result/{id} with your own key, or GET /v1/checks to list past checks.

Keep your original

If you need the document later, keep a copy on your own device or storage, unaltered. Re-saving it, printing to PDF or compressing it creates a new file, and a later re-check of that new file may give a different result. The result describes the file you submitted; the file itself stays with you.

Basics & Scope

Yes. HTPBE? looks for evidence that an existing file was changed, so a document that was false from the start can show none. Confirm critical documents with the issuer.

Reading Your Results

Every date and time is shown in UTC so that everyone sees the same absolute time, whatever timezone a PDF recorded its dates in. To get local time, add your UTC offset.

Read the full answer

Usually clock drift: the device that created the file had an inaccurate clock. Look at the date together with the verdict and the document’s source, and check important documents independently.
