Work with forms

Acrobat Reader’s form related features provide support for both traditional Acroforms and Fill & Sign forms.

Form type vs. features

There are two main types of forms–Acroforms and Fill & Sign forms–and each has a slightly different set of features.

  • Acroforms (traditional forms authored in Acrobat) contain form fields in which you can directly enter data, check boxes, and so on. These can be filled in on any platform and edited in Acrobat. You cannot edit or remove Acroform form fields on a mobile device.

  • Fill & Sign forms are simple forms you can create 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. Note that you cannot add Fill & Sign fields to an Acroform.

Acroform features

Fill out a form

Acroforms already contain form fields. You cannot add or remove form fields from an Acroform.

  • To fill out a form, simply tap a form field.

  • After entering data, tap outside a field to save the field data.


Tab through fields

To navigate through fields tap the right or left arrow.


Reset form fields

To clear a field:

  1. Select any field.

  2. Tap Reset.

  3. When asked to confirm the reset, tap Cancel or Reset.

Bluetooth keyboard navigation

To help you use all your devices and peripherals and speed up your use of forms, Acrobat Reader supports Bluetooth keyboard navigation in forms.

JavaScript API support

In Acroforms, Acrobat Reader supports the use of JavaScript for form field calculation and validation as well as formatting. For details, see the Mobile API Reference.

Fill & Sign features

Fill & Sign features are not available in Acroforms and those PDFs which are signed or security protected. For those PDFs, the Fill & Sign menu bar does not appear.

Fill & Sign provides additional features which streamline form fill-in:

  • Autozoom if the field size is too small for reading.

  • Snapping left when tapping in text fields (LTR locales only).

Create and edit a form

You can easily turn almost any PDF into a form and either send it to others or fill it out yourself.

To create a form in an open document:

  1. Tap editicon > fillsignicon to show the Fill & Sign toolbar.

  1. Select a form tool; for example, a text field or checkbox.

  2. Enter data. By default, the app suggests entries for text fields.

  3. Tap checkicon to exit Fill & Sign mode.

When you place a form element, a context menu provides options for changing the font size, deleting the element, and so on.



You can copy text from your clipboard to text fields.

Automatic form fill-in

By default, the app uses your form fill-in history to suggest words in subsequent forms. This feature saves time, especially on a mobile device. Sources for suggestions include the following:

  • Data from saved forms: If the first two letters match data you’ve entered in past (and saved) forms, suggestions are populated from that usage history.

  • Date formats: Typing the first letter or any number in the current date suggests the following date formats: 8/06/2018; Aug 6, 2018; August 6, 2018.

To disable this feature:

  1. Tap profileicon > Preferences.

  2. Disable Suggest previously used words when filling forms.


Clear form data history

You usage history is saved from completed forms. This allows the app to make suggestions as you type in form fields. To clear your suggestion history:

  1. Tap profileicon > Preferences.

  2. Tap Clear Suggestions > Remove.

Sign forms

Signing is a simple process, especially if you’ve already created your signature. Simply tap signicon and place your signature.

Paste text into text fields

When you copy text to your device clipboard, you can paste that text into a text field by simply long pressing the field and tapping Paste.

Undo and redo

As you fill in a form, you can undo and redo any action (except signing). Simply tap undoicon or redoicon in the upper right menu or above the keyboard (if it is visible).


Delete form fields

To remove a field:

  1. Tap any field.

  2. Tap deleteicon
