Question details

The user wants to know if it is possible to import and export fillable PDF form data as FDF files using Adobe Acrobat on mobile or web platforms to reuse information across forms.

Importing and Exporting FDF Form Data in Acrobat Mobile and Web
Product
Adobe Acrobat Mobile and Web
Device & OS
iOS (iPhone) and Web
Scenario
Reusing filled information across multiple PDF forms on an iPhone without combining PDFs or manually re-entering the same data.
Observed behavior
The user is unable to find the functionality to import or export FDF form data in the mobile or web versions of Adobe Acrobat because it is missing.
Before you start

Ensure you have access to a desktop or Mac computer, as handling FDF files and executing custom form scripts currently requires a full desktop PDF application.

Solution 1Recommended

Use the Desktop Version of Adobe Acrobat for FDF Files

Since Acrobat mobile and web apps lack custom scripting support, you must use the desktop application to import or export FDF form data.

FDF (Forms Data Format) files rely on custom background scripts to map the exported data back into the correct PDF form fields. Because Adobe Acrobat mobile and web platforms do not support these advanced desktop-level scripts, you cannot perform this action entirely on an iPhone or a web browser.

1
Transfer your PDF files

Send the blank PDF form and your saved FDF data file from your iPhone to your Windows or Mac computer via email, cloud storage, or file sharing.

2
Open the PDF in Acrobat Desktop

Launch the desktop version of Adobe Acrobat and open the fillable PDF form you wish to populate.

3
Access the Prepare Form tool

Navigate to the 'Tools' menu at the top, select 'Prepare Form', and click on the 'More' options (often represented by a gear icon or three dots in the right pane).

4
Import or Export Data

Select 'Import Data' to browse for your FDF file and populate the form, or choose 'Export Data' to save the currently filled fields as a new FDF file for later reuse.

Frequently Asked Questions

What is an FDF file and why is it useful?

An FDF (Forms Data Format) file is a lightweight text file that contains only the data entered into a PDF form, rather than the entire document. It is highly useful for saving form responses independently and importing them into identical blank forms to save time on manual data entry.

Why does Adobe Acrobat mobile not support FDF imports?

Adobe Acrobat mobile and web applications are designed to be lightweight and currently do not support the desktop-level custom scripting engine required to accurately map and execute FDF data imports into PDF fields.

Is there a workaround for keeping form data together on an iPhone?

If you cannot use FDF files, a common workaround on mobile is to save the filled PDF as a flattened copy, or use the 'Combine Files' feature (requires a premium subscription) to merge multiple filled PDFs into a single document instead of moving the raw data.
