Sign PDF documents

Last updated on Dec 2, 2024 | Also applies to Adobe Acrobat Sign

Before you begin

We're rolling out a new, more intuitive product experience. If the screen shown here doesn’t match your product interface, select help for your current experience.

In the new experience, the tools appear on the left side of the screen.

Overview

You can sign a document to attest to its contents or approve the document. This document explains how to sign a document or agreement using Acrobat or Reader desktop application.

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 date. When you save the document, the signature and text become part of the PDF.

Try it yourself
Fill and sign your documents in a few simple steps

Open Acrobat

Note:

You can also capture a picture of your signature on mobile using Adobe Acrobat Reader mobile app and save it in Adobe cloud storage so that it's synced and available for use across your desktop and other mobile devices. For more information, see Capture your signature on mobile and use it everywhere.

Open the PDF document. Select E-sign from the global bar.
Create your signature and initials if not already done. To do so:
1. To add a signature, select Add signature. In the dialog that appears, type, draw, or add an image of your signature and then select Done.
2. To add your initials, select Add initials. In the dialog that appears, type, draw, or add an image of your initials and then select Done.
Select your signature.
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.

To fill the PDF form with your desired color, from the Quick actions toolbar, select the Color icon and then select a color.

By default, the signature color is black. To retain the default color of the signature, make sure the Keep signatures black option is unchecked.

Note:

For more information on filling your form, see Fill out your PDF form.
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.

You can choose to type, draw, or import a signature image. Added signatures and initials are saved for future use.

Select Apply, and then click on the place in the PDF where you want to place the signature or initial.
To move the placed signature or initial, select the field to highlight it and then use the arrow keys. To resize or delete the field, use the options in the field toolbar.

Note:

If you want to use an image as your signature:

Sign your name in black ink on a clean, blank sheet of white paper. Sign in the middle of the paper so you don't photograph or scan the edges.
Photograph or scan your signature. If you are taking a picture of your signature, make sure that the page is lit and that no shadows fall across the signature.
Transfer the photo or scan to your computer. Acrobat/Reader accepts JPG, JPEG, PNG, GIF, TIFF, TIF, and BMP files. You do not need to crop the image. Acrobat/Reader imports just the signature if the photo or scan is fairly clean.

Sign an agreement

If you receive an email request for a signature from someone using Adobe Acrobat Sign, you can access the agreement from the link in your email or through your Acrobat or Acrobat Reader desktop application. You will see a notification that an agreement has been shared with you for signing.

You can sign the agreement using one of the following two ways:

Go to Acrobat or Acrobat Reader Home and then from under Agreements, select Adobe Acrobat Sign.

It takes you to the Adobe Acrobat Sign page where all the agreements shared or received for signature are displayed.
Double-click the agreement with the Waiting For You status, or select the agreement, and click Sign in the right-pane. The agreement opens.
Select the fields and enter the required information.
Select the signature field and then select Apply.
