Quickly fill and sign any PDF form online
To sign a PDF document or form, you can type, draw, or insert an image of your handwritten signature. You can also add text, such as your name, company, title, or the date. When you save the document, the signature and text become part of the PDF.
Open the PDF document or form that you want to sign.
Click the Sign icon in the toolbar. Alternatively, you can choose Tools > Fill & Sign or choose Fill & Sign from the right pane.
The Fill & Sign tool is displayed. Click Fill and Sign.
The form fields are detected automatically. Hover the mouse over a field to display a blue box. Click anywhere in the blue box, the cursor will be placed at the right position automatically. Type your text to fill the field.
You can choose your desired color to fill the PDF form. Click the color button in the Fill & Sign menu and choose your desired color.
By default, the signature color is black. To retain the default color of the signature, make sure the Retain Original Color For Signature option is unchecked.

Click the Sign icon in the toolbar, and then choose whether you want to add your signature or just initials.
If you have already added signatures or initials, they are displayed as options to choose from.
If you've already added your signature or initials, just select it from the Sign options, and then click at the place in the PDF where you want to add your signature. Skip to the next step.
If you are signing for the first time, you see the Signature or Initials panel. Below is an example of the Signature panel.
Click Apply, and then click at the place in the PDF where you want to place the signature or initial.
To move the placed signature or initial, click the field to highlight it and then use the arrow keys. To resize or delete the field, use the options in field toolbar.
If you want to use an image as your signature:
The creator of a PDF can encrypt the document with a certificate for verifying digital signatures. Certificates that you receive from others are stored in a list of trusted identities. This list resembles an address book and enables you to validate the signatures of these users on any documents you receive from them.
