Create and Distribute Forms with Adobe Acrobat Pro DC

Use the Prepare Form tool in Acrobat Pro DC desktop to add interactive fields, then distribute the file to collect mobile signatures.

Prepare the Form

Open your document in Adobe Acrobat Pro DC. Go to Tools at the top menu and select Prepare Form. Acrobat will automatically detect existing fields or let you start from scratch.

Add Interactive Fields

Distribute via Email

Fill and Sign on Mobile

Instruct your recipients to open the email on their mobile device and use the free Adobe Acrobat Reader app to tap the fields, enter their information, and draw their signature.
