How to draw a signature and put it on a PDF

Open the PDF in the PDF editor, press Sign, and draw your signature with a finger, stylus or mouse (or type your name, or upload a photo of it). Press Place signature: it lands on the page, where you drag it into place and resize it from a corner. Then press Download PDF.

Steps

1. Open the PDF editor and choose your PDF.
2. Scroll to the page that needs your signature.
3. Press Sign in the toolbar.
4. Under How to sign, choose Draw, Type or Upload:
   • Draw on the signature pad. Set the Pen width if the line is too thin or thick.
   • Type your name and tap a handwriting style.
   • Upload a photo or scan of your signature on plain white paper; the paper is removed and the ink trimmed.
5. Pick an Ink colour, then press Place signature.
6. The signature lands in the middle of the page. Drag it onto the signature line and resize it from a corner.
7. Add a date or your printed name with Text if the form asks for it.
8. Press Download PDF.

Which way to sign

A signature drawn with a mouse often looks shaky. On a computer, Upload gives a more natural result: sign on paper, take a photo with your phone, and choose the photo.

Keep a signature to reuse

If you sign documents often, make a transparent PNG once in the signature maker and keep it. In the PDF editor you can then add it with Upload, or as an image, each time, and it looks the same on every document. The signature maker also offers more control over paper removal, with a threshold and speck removal for photos.

Before you download

• Check every page that needs a signature or initials. Multi-page agreements often ask for initials at the foot of each page. Place a typed or drawn copy on each.
• Fill the form fields. If the PDF has fillable fields, they show as tinted boxes; type into them directly. They stay fillable in the downloaded file.
• Do not hide text with whiteout. The editor's whiteout covers content so it does not show, but the original text is still inside the file.
• Undo steps back through changes; moving or resizing counts as one step.

A signature picture, not a certificate signature

The editor puts a picture of your signature on the page, like signing on paper and scanning it. It does not add a certificate-based digital signature, which proves who signed a file and that it has not changed since. Many everyday forms and letters accept a pasted signature; some contracts and government filings need a certificate signature. Ask whoever sent you the document which they accept.

To check a certificate signature in a PDF someone sent you, see verify a PDF signature.

Privacy

The PDF, your signature and your name stay in your browser. Nothing is uploaded to a server. That matters for the documents people usually sign: rental agreements, job offers, school forms.

Questions

Can I sign a PDF on my phone?

Yes. Open the PDF editor in your phone's browser, press Sign and draw with your finger. Turn the phone sideways for a wider pad.

Can I move the signature after placing it?

Yes. Drag it anywhere on the page and resize it from a corner until you download.

Is the signed PDF legally binding?

It is a picture of your signature on the page. Whether that is accepted depends on the document and where you live; check with the person who asked you to sign.

Does it add a watermark to my PDF?

No. The download has no watermark, and there is no sign-up or limit.
