How to Sign a PDF Electronically for Free

June 22, 2026 1 min read

The print-sign-scan dance is dead. You can add a signature to a PDF in under a minute, right from your browser, without a printer in sight.

Three ways to create a signature

With Sign PDF you can:

  • Draw it with your mouse, trackpad or finger.
  • Type your name and pick a handwriting-style font.
  • Upload a photo of your signature.

Then just click where you want it on the page, resize, and download the signed document.

Prefer to make the signature first?

Filling out forms

If your PDF has actual form fields (checkboxes, text boxes), use Fill PDF Form instead — you can type directly into the fields and optionally flatten the form so the values can't be changed afterwards.

Stamps and dates

Need "APPROVED" or today's date on a document? Stamp PDF and Date Stamp PDF have you covered.

Is an electronic signature legal?

In many countries, a clear intent to sign plus a visible signature is legally recognised for most everyday agreements. For high-stakes contracts you may need a certificate-based (qualified) e-signature from a specialised provider. For the vast majority of forms, invoices and letters, a visible signature is exactly what's expected — and it all happens privately on your device.
