Sign PDF

Draw or type your signature and place it on any PDF page.

Your files never leave your device.

When to use it

Sign PDF lets you add your signature to a PDF without printing, signing and scanning. Use it for rental agreements, job offers, permission slips, invoices, delivery notes and any form someone emailed you with “please sign and return”. You can draw, type or upload your signature, place it exactly where it belongs, and download the signed copy in a minute.

How to sign a PDF

  1. Tap Choose PDF file, or drag a PDF (up to 100 MB) onto the box.
  2. Under Create your signature, choose how:
    • Draw: sign with your finger or mouse. Pick Black or Blue ink; Clear starts again.
    • Type: enter Your name and tap one of three handwriting styles.
    • Upload image: tap Choose signature image and pick a photo of your signature.
  3. Press Use this signature.
  4. Tap the page where you want to sign. Drag the signature to move it, use the corner handle to resize it, and the red button to remove it. Repeat on other pages if needed.
  5. Press Download signed PDF.

A worked example

Your landlord emails a 6-page lease to sign on page 5 and initial at the bottom of every page. Draw your full signature, press Use this signature, scroll to page 5 and tap the signature line, then shrink it to fit. Press Change signature, type your initials in the Caveat style, and tap the bottom corner of each page. Download the signed PDF and reply with it attached.

Tips for a neat signature

  • Draw on a phone or tablet if you can; a finger gives a more natural line than a mouse.
  • Zoom in your browser to place a signature precisely on small lines.
  • Keep the size realistic. About 4 to 6 cm wide looks right on most documents.
  • Use blue ink if the recipient wants to tell the signed copy from a photocopy.

Common mistakes

  • Signing the wrong page. Check the page numbers on the document before you download.
  • Uploading a photo with shadows. Shadows can leave grey patches; retake it in even light.
  • Forgetting to fill in the date or name fields next to the signature. If the PDF has form fields, complete them with Fill PDF Form first.
  • Sending the unsigned copy. Attach the downloaded file, which ends in “-signed.pdf”.

Private by design

Your PDF and signature are processed only in your browser. Nothing is uploaded, stored or reused.

Complete form fields with Fill PDF Form, number the pages with Add Page Numbers, or lock the signed copy with Protect PDF.

Frequently asked questions

Is a signature added this way legally valid?

In many countries, including the US, UK and EU, an electronic signature like this is accepted for most everyday agreements, such as leases, forms and consent letters. Some documents, like wills or certain property deeds, need a witnessed or certified digital signature. If in doubt, ask the person who sent the document.

Can I sign on more than one page?

Yes. Tap each page where you need a signature or initials. Every placement can be moved, resized or removed before you download.

Is my signature saved anywhere?

No. The signature and the PDF stay in your browser and are never uploaded. Close the page and they're gone.

How do I make an upload of my paper signature look clean?

Sign with a dark pen on plain white paper, photograph it in good light from straight above, and crop close to the signature. The white background is removed automatically.

Can I fill in form fields too?

This tool places signatures. To type into form fields first, use Fill PDF Form, then sign the result here.
