How to sign a PDF in 3 steps

1. Add your PDF. Drag the file onto the page or choose it from your device.
2. Add your signature and fields. Draw your signature with a mouse, trackpad or finger, or type your name and pick a cursive style. Then place it on the page and add a date, text or a checkbox where needed.
3. Download the signed PDF. Your signature and fields are flattened into the document so it opens the same way everywhere.

What you can add to a PDF

• Signature. Draw it in blue, black, pink or green ink, or type it in one of three calligraphy styles.
• Text. Fill in names, addresses, amounts and any other blank.
• Date. Drop in today's date with one click.
• Checkboxes. Tick the boxes on forms and agreements.
• Erase. Cover a mistake or an old entry before you fill in the correct one.

Works on phone and computer

The editor adapts to small screens, so you can sign on a phone while travelling. On a touch screen, draw your signature with your finger. You can add more pages from another PDF if the document needs them.

Need other people to sign too?

Signing your own copy is only the start. Create a free account to send a document for signature by email, SMS or WhatsApp, track each signer's progress, and keep the finished contract with its Certificate of Completion in a private vault. Looking at other tools first? See how KamiSign works as a DocuSign alternative.

Is it secure?

If you sign as a guest, your PDF stays in your browser. It is uploaded only when you send it or save it to your vault, where it is encrypted. Read our privacy policy for details.
