Sign a PDF Using Acrobat Reader DC (Mac & Windows)

Acrobat Reader lets you sign PDFs and incorporate that signature into the file. Note: Some documents have security applied that prohibits electronic signatures. Print such documents and then sign the printed copy.

To sign (or initial) using Acrobat Reader DC:

1. Open the PDF document or form you want to sign (or initial) in Acrobat Reader.
   Note: If you are viewing a PDF on the web, download the PDF first before you sign it.
   
2. If you are prompted to sign in to Adobe DC (Document Cloud), click "Skip."
3. In the toolbar, select the Sign Tool . Important: DO NOT use the "Fill & Sign" Adobe Sign (Adobe’s E-Signature Service) in the sidebar menu, as this is a paid service & not necessary.
4. Select "Add Signature" (or "Add Initials").
   
5. Select one of the 3 options: Type, Draw, or Image:
   
   • Type in your signature (you can change the style & size).
   • Draw your signature with a trackpad or mouse.
   • Upload an image of your handwritten signature.*
6. Once you have created a signature (or initials) to use, use the mouse to move your signature (or initials) into position on the page.
   Note: You can also add text, such as your name, company, title, or the date.
   
7. Save the PDF.
   The signature (or initials) become part of the PDF.

* Notes about using 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. If the photo or scan is fairly clean, Acrobat Reader imports just the signature.

Sign a PDF Using the macOS Preview App

1. Open the PDF document or form you want to sign in the macOS Preview app.

3. Select to use either the Trackpad or Camera & follow the on screen instructions to create a signature.
   
4. Once you have created a signature to use, use the mouse to move your signature into position on the page.

Many programs, including Microsoft Word, have the ability to edit PDF files.
