Fill and sign forms


You can fill and sign forms both online and offline. You don’t need to be connected to the internet to fill out and sign forms.

Acrobat Reader app provides support for the following two types of forms:

  • Acroforms: These contain form fields where you can directly enter data, check boxes, and more. Users can fill the fields from any platform and can edit in Acrobat. However, you cannot edit or remove Acroform form fields on a mobile device.

  • Fill & Sign forms: You can create these forms on any platform, including mobile devices. Fill & Sign form fields are similar to annotations: you can select a form element from the form tool bar and tap anywhere on the PDF to place it. Acrobat also supports adding and editing Fill & Sign form fields.
