- Product
- Device & OS
- not provided
- Scenario
- Sharing a fillable PDF for a customer or client to complete, save, and return.
- Observed behavior
- The information entered into the PDF form fields is completely missing or lost after the recipient saves and reopens the file.
Ensure the original PDF form was created properly with designated interactive form fields and test it locally before sending it to others.
Ensure the Recipient Uses a Compatible PDF Viewer
Many built-in browser PDF viewers or basic preview apps do not support saving interactive form data properly. The recipient must use a dedicated PDF application.
When a user opens a fillable PDF in certain default web browsers (like Chrome, Edge, or Safari) or default system viewers (like Mac Preview), the software may allow them to type into the fields but will fail to save the entered data properly. Using a standardized PDF reader resolves this issue.
Ask the customer which application they used to open, fill out, and save the PDF document.
Instruct the customer to download and install a dedicated application that supports interactive form fields natively, such as WPS Office or Adobe Acrobat Reader.
Have the customer open the PDF directly within the installed application rather than double-clicking the file from their downloads folder, which might default back to a web browser.
Ask the recipient to fill out the form fields again and use the 'Save As' function from the 'File' or 'Menu' tab to create a new copy of the filled document, ensuring all data is permanently preserved.

Fill and Save PDF Forms Securely with WPS Office
WPS Office provides a comprehensive PDF editor that fully supports interactive fillable forms, ensuring no data is lost when saving. It is a lightweight, free, and secure alternative for managing all your document needs.
- 1. Install WPS Office: Download and install WPS Office on your computer or mobile device.
- 2. Open the PDF document: Launch WPS Office and open the fillable PDF form using the WPS PDF tool.
- 3. Fill in the information: Click on the highlighted text fields within the document to enter your required information.
- 4. Save the form: Go to the 'Menu' in the top-left corner and select 'Save' or 'Save As' to preserve your entered form data safely.

Frequently Asked Questions
Why does a PDF form show empty fields when I open it again?
This usually happens if the form was filled out in a web browser or a basic system preview application that does not support the saving of interactive form fields. Opening the file in a standard, dedicated PDF editor will often reveal whether the data was actually saved or completely lost.
Can I recover form data that disappeared after saving?
Unfortunately, if the PDF was saved using an incompatible viewer that failed to write the form field data to the file, the lost information cannot be recovered. You will need to fill out the form again using a fully compatible PDF reader.
How do I make sure a PDF form is fillable before sending it?
Open the PDF in a dedicated PDF editor like WPS Office. Check if the form fields are highlighted or interactive when you click them. Test the form by entering sample data, saving it as a new file, and reopening it to verify that the information is preserved successfully.
What is the best way to share a fillable PDF with customers?
Send the PDF as an email attachment or via a secure cloud storage link. It is highly recommended to explicitly instruct the recipient to download the file to their computer and open it with a dedicated PDF reader, rather than completing it directly in their web browser.
