Date Stamp PDF: limits and things worth knowing

• The date comes from your device's clock and is drawn onto the page as ordinary content.
• A drawn date is a label, not evidence. It proves nothing about when the document was actually created or signed — use PDF Fingerprint if you need something tamper-evident.
• Choose the format deliberately for an international audience: 03/04/2026 is read as two different dates on opposite sides of the Atlantic. The ISO form, 2026-04-03, is unambiguous.

Is it private and secure?

Your privacy is built in. Date Stamp PDF does all processing on your own device using client-side code, so your files are never transmitted, stored or seen by anyone — including us.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.

We also measured the competition. Our PDF upload audit recorded how many bytes each of 20 online PDF tools actually transmits: 12 of the 13 measurable services uploaded the whole test file, and Filevane transmitted 0.00 MB.
