Tentang Alat Ini
Timestamp PDF adds a verifiable trusted timestamp to a document, supporting long-term signature validity through LT and LTA profiles. You can prove exactly when the PDF existed and demonstrate that it has not been altered since that moment. The timestamp becomes part of the file and remains checkable later.
Contractors record the moment an agreement is finalized before the PDF moves to a signature workflow. Governments and archives establish provenance for submissions and digital records that must survive retention schedules. Anyone defending a document through audit or dispute can supply a timestamped, integrity-checked file instead of relying on guesses about dates. The same proof supports e-discovery responses and regulatory submissions where timing is part of the compliance story.
Timestamping runs in your browser and calls a trusted authority for the time attestation while your content stays local. Verify the result afterwards to confirm the certificate chain is intact. Free, no account, and cryptographic proof that turns "this was sent" into "this existed, unchanged, at a provable moment".
Practical guidance before you use Stempel Waktu PDF
Best for real document workflows
Use Stempel Waktu PDF when you need a quick browser-based result without creating an account or sending routine documents through an unnecessary upload workflow. Intellectual Property is a common example: Establish clear priority proof of patents, drafts, and ideas before public release.
Privacy and file handling
EasyPDFNex prioritizes local processing in your browser. That means supported PDF operations run on your device, not in a public cloud queue. For sensitive files, review the output before sharing it, close the browser tab after downloading, and avoid processing documents you are not authorized to edit.
Quality checks after processing
After you apply and timestamp, open the result and check page order, text readability, signatures, links, and form fields. If the source file is scanned, encrypted, very large, or damaged, try a related workflow such as sign pdf, encrypt pdf, sanitize pdf before repeating the task.
Start with a clean source file whenever possible. For Stempel Waktu PDF, the first step is usually "Upload PDF Document": Select the target PDF file you want to timestamp. This simple preparation step prevents most failed exports, missing pages, and formatting surprises.
Editorial review note
This guidance is maintained by the EasyPDFNex editorial team and reviewed for practical PDF workflow accuracy. Tool pages are written to explain when a feature is useful, what to check before download, and where browser-based processing has limits.

Pertanyaan yang Sering Diajukan
What is a trusted timestamp (RFC 3161)?
An RFC 3161 timestamp is a cryptographically signed token issued by a recognized third-party authority (TSA) that links a document hash to a specific, verified clock source.
Do I need a digital certificate?
No, the cryptographic signature is provided directly by the trusted TSA server, making the process effortless for document owners.
Does the TSA see my document contents?
Never. The tool only sends a secure SHA-256 hash of your document to the TSA server, keeping your actual document completely private.
