How to Create a Fillable PDF Form for Adobe Acrobat Reader Users
Question details
The user needs to create interactive PDF forms that recipients can successfully fill out, save, and potentially flatten using the free Adobe Acrobat Reader application.

- Product
- Adobe Acrobat Pro
- Device & OS
- not provided
- Scenario
- Distributing a fillable PDF to a wide audience who will likely open and complete the form using the free Adobe Acrobat Reader rather than premium PDF software.
- Observed behavior
- Form creation and distribution require specific steps in Acrobat Pro, especially if the document involves calculations, needs to be saved by older Reader versions, or requires flattening/locking after completion.
Ensure you have Adobe Acrobat Pro installed to create and configure the interactive form fields, as the free Adobe Acrobat Reader can only be used to fill out forms, not create them.
Create and Configure the Fillable PDF in Acrobat Pro
Use Adobe Acrobat Pro's Form Preparation tool to add interactive fields and ensure compatibility so users can save their data in Acrobat Reader.
While Adobe InDesign is great for designing simple layouts to collect basic text information, Acrobat Pro is required to add complex form fields, calculations, and interactive behaviors.
Open Adobe Acrobat Pro, go to the 'Tools' menu, and select 'Prepare Form'. Choose an existing document or scan a file to let Acrobat automatically analyze and place form fields.
Use the top toolbar to insert additional fields such as text boxes, checkboxes, or dropdown lists. Right-click any field and select 'Properties' to configure calculations and formatting.
If your recipients are using older versions of Adobe Reader, go to 'File', select 'Save As Other', and choose 'Reader Extended PDF' so they have permission to save their filled data.
Save your completed PDF and distribute it to your users. They can now open the file in the free Adobe Acrobat Reader, fill in the fields, and save the document.

Lock or Secure the Completed Form
Implement a workflow to lock the form fields after a user fills them out, as Adobe Reader cannot securely flatten PDFs on its own.
Create Fillable PDF Forms Easily with WPS Office

- 5. Save and Share: Save your document as a standard PDF file. It is now ready to be distributed and filled out by anyone.

Frequently Asked Questions
Can users save a filled form using the free Adobe Acrobat Reader?
Yes, modern versions of Adobe Acrobat Reader allow users to save filled forms. However, if your recipients use older versions of Reader, you must save the document in Acrobat Pro using the 'Reader Extended PDF' option to grant them saving rights.
Can Adobe Acrobat Reader flatten a PDF form?
No, Acrobat Reader cannot natively flatten form fields. To secure a form and prevent further editing, you must either add a digital signature field configured to lock the document or flatten it yourself using Acrobat Pro.
Should I use Adobe InDesign or Acrobat Pro to create PDF forms?
You can use Adobe InDesign to design the visual layout of simple forms, such as those collecting basic names and addresses. However, for adding interactive fields, complex calculations, or hidden layers, Adobe Acrobat Pro is required.
Why are form fields still editable after a user fills them out?
Standard fillable PDFs remain editable by design until they are explicitly locked or flattened. To prevent further changes after submission, configure your form with a locking digital signature field or instruct users to utilize the 'Fill & Sign' feature.
