Fill in PDF forms

Last updated on Dec 21, 2023 | Also applies to Adobe Acrobat, Adobe Acrobat 2017

This document explains how to fill PDF forms using Acrobat or Reader desktop application.

Is the form fillable?

Not all forms are fillable. Sometimes form creators don’t convert their PDFs to interactive fillable forms. Or, they intentionally design a form that you can fill in only by hand or with the Fill & Sign tool. These non-interactive forms are called flat forms.

Fill in interactive forms

An interactive form contains fields that you can select or fill in.

Interactive form in Acrobat — Interactive fillable form

A. Purple message bar indicates presence of fillable fields. B. When clicked, shows where fillable fields exist.

If necessary, right-click the document, and select either the Hand Tool or the Select Tool from the pop-up menu.

The pointer changes to a different icon as you move it over a field. For example, the Hand tool changes to an I-beam when you can type text into the form field. Some text fields are dynamic, meaning that they automatically resize to accommodate the amount of data you enter and can span across pages.
(Optional) To make form fields easier to identify, click the Highlight Existing Fields button on the document message bar. Form fields appear with a colored background (light blue by default), and all required form fields are outlined in another color (red by default).
Click to select options, such as radio buttons. Click inside a text field to type.

Press Tab to move forward or Shift+Tab to move backward.
When finished, click the submit button to either send the data to a server or create an email to send the data. The submit button can appear in the purple message bar at the top of the form or in the form content.

Fill in flat forms with the Fill & Sign tools

A flat form does not have interactive fields. However, you can use the Fill & Sign tools to add text and other symbols anywhere on the form. For instructions, see Fill out your PDF form.

Fill in flat forms in a browser

A common way to view a PDF form is in a web browser, for example, when you click a link on a website. If the form does not contain interactive fields, you can use the Fill & Sign tools to fill out the form. Save the form on your computer, and then open it directly in Acrobat or Acrobat Reader. For instructions, see Fill out your PDF form.

Save form on your computer — Save form, open in Acrobat or Acrobat Reader, and then choose Tools > Fill & Sign.

Auto-Complete forms (interactive forms only)

The Auto-Complete feature stores any entries that you type in an interactive form field. Auto-Complete then suggests or even automatically enters responses that match your typing in other form fields. The suggestions appear in a pop-up menu, from which you can select a match. The Auto-Complete feature is off by default, so you must enable it in the forms preferences if you want to use it.

To remove an entry from the Auto-Complete memory, such as a misspelled entry that you found and corrected later, edit the list in the preferences.

Note:

The forms preferences apply to the way the application handles open forms as you work. The preferences aren’t saved with the PDF forms themselves.

Enable the Auto-Complete option

Choose Edit > Preferences (Windows) or Acrobat / Acrobat Reader > Preferences (Mac OS).
Select Forms on the left.
Under Auto-Complete, choose Basic or Advanced from the menu.
Select Remember Numerical Data if you want the Auto-Complete memory to store numbers that you type into forms.

Note:

When you select an option in the Auto-Complete menu, a description of how it affects the Auto-Complete behavior appears in the text area below.

Delete an entry from the Auto-Complete memory

Open the Preferences dialog box.
Select Forms on the left.
Click Edit Entry List under Auto-Complete.
In the Auto-Complete Entry List dialog box, do one of the following, and then click Yes in the confirmation dialog box:
- To remove all of the entries, click Remove All.
- To remove some of the entries, select the entries and click Remove. (Shift-click to select multiple adjacent entries; Ctrl-click to select multiple nonadjacent entries.)

Change flat forms to fillable (Acrobat Pro)
