Users need to resolve an issue where completed PDF form fields do not display their data during the signature workflow.

How to Fix Filled PDF Form Fields Appearing Blank in Adobe Sign
Product
Adobe Acrobat / Adobe Sign
Device & OS
iOS (iPhone)
Scenario
Sending a filled PDF document for e-signature via Adobe Sign after completing the form fields on a mobile device.
Observed behavior
PDF fields that were successfully filled out in Acrobat on an iPhone appear entirely blank when the document is routed through Adobe Sign.
Before you start

Ensure you have access to a desktop computer, as managing field permissions, participant roles, and saving configurations for Adobe Sign is generally more reliable on the desktop version.

Review and Adjust Field Permissions and Participant Roles

Reassigning the form fields ensures that the data inputted by the sender is properly retained and remains visible to all participants in the signing workflow.

When PDF forms are filled out on a mobile device and sent through Adobe Sign, the system relies on role assignments to display data. If form fields are assigned exclusively to the 'Sender' or have restrictive permissions, Adobe Sign may clear or hide the values when the document is sent to the next signer.

1
Transfer the PDF to a Desktop

Save the filled PDF document from your iPhone and open it on a desktop computer where you have full access to Adobe Sign preparation tools.

2
Upload to Adobe Sign

Log into your Adobe Sign account, initiate a new send process, and upload the problematic PDF document.

3
Open the Authoring Environment

Check the box that says 'Preview & Add Signature Fields' before clicking 'Next' to enter the document preparation screen.

4
Modify Field Assignments

Double-click on the blank form fields to open their properties. Change the 'Assigned To' role from 'Sender' to 'Anyone' or assign it explicitly to the required participant.

5
Save and Send

Click 'OK' to save the new field properties, verify that the data is displaying correctly in the preview, and then send the document.

Review and Adjust Field Permissions and Participant Roles
Testing Workflows: Always test the form by sending it to your own alternate email address first to confirm that the fields are properly configured and visible before sending it to a client.

Frequently Asked Questions

Why are my filled PDF fields invisible when opened in a web browser?

Many built-in web browser PDF viewers do not fully support interactive form fields. To view the data properly, the recipient should download the file and open it in a dedicated PDF application like WPS Office or Adobe Acrobat.

How can I prevent form fields from going blank when emailing a PDF?

To lock the information in place, you can 'flatten' the PDF before emailing it. You can do this by using a 'Print to PDF' feature, which merges the interactive form fields with the background document.

How do I assign form fields to a specific recipient in Adobe Sign?

When preparing your document in the Adobe Sign authoring environment, double-click on the specific form field, locate the 'Assigned To' dropdown menu in the properties window, and select the email address of the required participant.
