Fill in a form and sign it

Updated October 21, 2026

You can fill in and sign a PDF without printing it.

Fill in the form

1. Open the PDF. If it has form fields, click a field and type, or click a check box to tick it.
2. Press Tab to move to the next field.
3. If the form has no fields, choose Text on the toolbar and click on the page where you want to type.

Add your signature

1. Choose Sign on the toolbar, or Tools › Fill & Sign.
2. Under Signatures, choose + Add signature. (Under Initials, + Add initials works the same way.)
3. Draw your signature with the mouse or a pen, Type your name, or choose an Image of your signature.
4. Leave Save for next time on to keep it for later, then choose Place signature.
5. Click on the page where the signature should go.

Next time, your saved signature is in the Sign menu: click it, then click on the page.

The Sign menu also has Add today’s date, and marks (a check, cross, dot, line or circle) for paper-style forms.

Save

Choose File › Save (Ctrl+S), or File › Save As… (Ctrl+Shift+S) to keep the blank form as it was.

This adds a picture of your signature. If someone needs proof that the document hasn’t changed since you signed it, use a digital signature instead.
