Create your signature by drawing it, typing your name, or using a photo of it — then place it on any page, add a date or initials, and save the signed PDF.

How it works

Sign PDF in three steps.

  1. Choose the PDF

    Select the contract, form or letter to sign.

  2. Create your signature

    Draw it with a mouse, trackpad or finger, type your name in a handwriting style, or choose an image. Save it for reuse if you like.

  3. Place it and save

    Click where it should go, adjust it, add any text such as the date, and save the signed PDF.

Private by design

Your PDF never leaves your device.

Sign PDF runs inside your browser tab. The file you choose is read from your device, processed there, and the result is saved back to your device — it is never uploaded to a Pyrbit server, so there is no copy to keep or delete.

Processed in your browser

The Pyrbit PDF engine runs on your computer or phone, not in the cloud.

No upload

Your document isn’t sent anywhere — not to us, and not to a third-party converter.

Sign-in is for your plan only

Your Google account keeps track of your free daily document and Pyrbit Pro. It never gives us your files.

Prefer offline?

The Pyrbit PDF apps do the same work on your phone, tablet or Mac — even without a connection.

FAQ

Sign PDF questions.

Is this a legally binding signature?

It’s an electronic signature — an image of your signature on the document — which is accepted for many everyday agreements. Some documents require a certificate-based digital signature; check what the recipient needs.

What’s the difference from a digital signature?

A digital signature uses a certificate to prove who signed and that the file hasn’t changed since. For that, see Aadhaar Digital Signature, which signs with your own .pfx/.p12 certificate.

Which image works best for an uploaded signature?

A PNG with a transparent background looks best; a clear photo of your signature on white paper also works.

Is Sign PDF free?
