Your files are processed entirely in your browser using built-in web technologies. They are not uploaded to our servers, and closing the page clears them from memory.

How to use the Sign PDF

  1. Choose the PDF to sign.
  2. Create your signature — draw it with a mouse or finger, type your name, or upload a photo of it.
  3. Click the page to place it, drag and resize it, add the date if needed, then download.

What does this tool do?

The signature is added as an image on the page, exactly like signing a printout and scanning it — which is what most landlords, schools, HR teams and freelancers’ clients ask for. Uploaded signatures can have their white paper background removed automatically.

Your PDF is processed on your own device and never uploaded. Your signature is never stored.

Why use it?

  • Draw, type or upload.
  • Place on any page, any size.
  • No account or upload.

Accuracy and limits

  • This is a visual signature, not a certificate-based digital signature (PAdES). Documents that require a qualified or verified e-signature need a dedicated signing service.

Frequently asked questions

Is it safe to sign a PDF here?

Yes. Your PDF and signature are processed entirely in your browser and are never uploaded, so confidential contracts stay on your device.

Is this a legally binding e-signature?

It adds a visual signature, like signing a printout and scanning it, which is accepted for many everyday documents. It isn't a certificate-based digital signature with an audit trail; for contracts that require one, use a dedicated e-signature service.

Can I use a photo of my handwritten signature?

Yes. Sign on white paper, take a photo and upload it — the paper background is made transparent so only the ink sits on the page.

Can I add the date or my initials?

Yes. Use Date / text to add today's date, your printed name or initials anywhere on any page, then move and resize them.

Does it work on a phone?

Yes — draw your signature with your finger, place it on the page and download the signed PDF.
