Certificate Sign, Certify, and Validate PDF
Apply certificate-backed PDF signatures, certify restriction states, and inspect trust or tamper results in a dedicated in-browser security workflow.
Certificate signing stays separate from visual fill-and-sign so the trust workflow does not feel casual.Generate or import in-browser digital IDs, then validate trust, tamper, and timestamp state in the same route.Signed outputs can be saved to Files and reopened in the security workflow to confirm validation after reopen.

Workflow blueprint
How it works
The public entry point is intentionally short. You choose the file, land in the live tool, and finish the job with the controls already set for that task.
01
Upload one PDF and open the dedicated certificate-security tool.
02
Generate or import a digital ID, choose approval signing, certification, or validation-only mode, and review any lock-state warnings before export.
03
Save the signed PDF into Files, then reopen that saved copy in the same route to confirm trust, timestamp, and tamper state after reopen.
01
Apply approval signatures or certification signatures with explicit permission levels.
02
Inspect trusted, untrusted, changed, invalid, and timestamp states from the same tool.
03
Keep in-browser digital IDs and trust decisions explicit instead of hiding them inside the editor.

Common questions
Is this the same as Fill and Sign?
No. Fill and Sign is for visual self-signing and initials. This route is for certificate-backed PDF signatures, certification permissions, and trust validation.
Can I encrypt a PDF for recipients with certificates here?
Not yet. This first pass covers certificate signing, certification restrictions, and trust validation. Recipient certificate encryption is still out of scope.
