How to Fix Filled PDF Form Fields Appearing Blank in Adobe Sign
Question details
Users need to resolve an issue where completed PDF form fields do not display their data during the signature workflow.

- 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.
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.
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.
Log into your Adobe Sign account, initiate a new send process, and upload the problematic PDF document.
Check the box that says 'Preview & Add Signature Fields' before clicking 'Next' to enter the document preparation screen.
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.
Click 'OK' to save the new field properties, verify that the data is displaying correctly in the preview, and then send the document.

Fill and Sign PDF Forms Seamlessly with WPS Office
Avoid workflow glitches and missing data by using WPS Office to fill out PDF forms and add electronic signatures directly. It ensures your inputted data is flattened and remains visible across all devices and platforms.
- 1. Open the PDF Document: Launch WPS Office on your desktop or mobile device and open the PDF form you need to complete.
- 2. Fill the Form Fields: Tap or click on the interactive fields to directly enter your text, dates, or checkbox selections.
- 3. Add Your Signature: Navigate to the 'Fill & Sign' or 'Protect' tab, select 'Sign', and place your signature on the document.
- 4. Save and Share: Save the completed PDF to your device. WPS Office embeds the information into the document so it will not appear blank to the recipient.

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.
