Sign PDF

Add your signature to a PDF without printing or scanning — draw it with your mouse or finger, then drop it exactly where it belongs. You can also place initials, your typed name, today's date, and a company stamp, and drag or resize each element to fit the page. Everything happens in your browser, so the document you sign is never uploaded to a server.

How to sign a PDF with Allypdf

  1. Load the PDF you need to sign.
  2. Draw your signature or initials, or type your name, then drag each field onto the page.
  3. Position and resize every element with its corner handles until it sits exactly right.
  4. Click Sign to burn the elements into the PDF, then download the signed file.

Why "no upload" matters here

A document you sign is, by definition, one you are willing to be held to — a contract, a consent form, an agreement. Uploading it to a stranger's server just to add a signature is exactly the wrong trade. Allypdf places your signature on your own device, so the signed file and your signature image never leave your machine.

Common uses

  • Sign a contract or offer letter and send it back the same day.
  • Add your initials to every page of an agreement.
  • Fill in your name and the date on a form without printing it.
  • Stamp a company seal onto an invoice or letter.

Frequently asked questions

How do I sign a PDF for free?

Open the Sign PDF tool, load your file, draw or type your signature, drag it onto the page, and download the signed PDF. Free, with no sign-up and no watermark.

Can I move and resize the signature on the page?

Yes. Every element — signature, initials, name, date, and stamp — can be dragged to any position and resized from its corner handles until it fits the page exactly.

Are electronic signatures legally binding?

The tool creates a visual electronic signature, which many jurisdictions accept for everyday agreements; whether it is binding for a specific document depends on your local laws. It is not a certified cryptographic digital signature.

Is my document uploaded when I sign it?

No. The signature is placed in your browser and the PDF is rebuilt on your device, so the file you are signing is never sent to a server.
