Add Date to PDF

Processed in your browser

An undated signature is one of the most common gaps in informal agreements — and the date is exactly what you need when deadlines, interest, or repayment schedules are counted from signing. This tool stamps a date onto any page of a PDF, right where the document expects it.

Drop files here or tap to choose Processed in your browser — files never leave your device.

Pick the date, choose a format, place it next to the signature or in the header, and download. It works entirely in your browser.

How it works

  1. Add the PDF that needs a date.
  2. Choose the date and a format, such as day-month-year or month spelled out.
  3. Drag the date stamp to the right spot — next to a signature, in a blank field, or in the header.
  4. Download the dated PDF; the original file stays unchanged.

Your privacy

The tool runs entirely in your browser — your document never leaves your device.

Nothing is uploaded to a server, and nothing remains after you close the tab.

Your documents are never used to train AI models.

Common use cases

  • Add the signing date next to a signature that was placed without one.
  • Date each party's signature block on a loan agreement.
  • Stamp the effective date on a payment extension before sharing it.
  • Add a received date to documents you archive for your records.

Limitations

  • The date is placed as visible text on the page — it does not change any PDF metadata or prove when the document was really signed.
  • Password-protected files must be unlocked first.
  • If the page is a skewed scan, you may need to fine-tune the position by hand.

Frequently asked questions

Does the stamped date prove when the contract was signed?

No. It is a visible label, not evidence. Proof of timing usually comes from surrounding records — the email or chat where the signed file was exchanged, or the bank transfer that followed. Stamp the true date and keep those records.

Can I choose the date format?

Yes. Common formats such as 15/03/2026, 2026-03-15, or 15 March 2026 are available, so you can match the style used in the rest of the document.

Can I add more than one date?

Yes. Place as many date stamps as the document needs — for example, one beside each party's signature.

Should the date match the day the money was transferred?

Not necessarily. The signing date records when the agreement was made; the transfer slip records when money moved. Both are useful, and it is fine for them to differ — just make sure the agreement states its own dates clearly.

Is it wrong to backdate an agreement?

Writing a date earlier than the real signing date can misrepresent the facts and cause serious problems in a dispute. If you are documenting an older arrangement, use today's date and state in the text when the original agreement was made.
