Why PDF Submit Buttons Do Not Work in Acrobat Reader Mobile
Question details
Users are unable to use the Submit by Email button embedded within interactive PDFs when opening the document on mobile devices.

- Product
- Adobe Acrobat Reader Mobile
- Device & OS
- iOS (iPad) and Mobile
- Scenario
- Attempting to submit a filled interactive PDF form directly to an email address by tapping an embedded submit button.
- Observed behavior
- The PDF Submit by Email button does nothing or fails to launch the email application on an iPad or mobile device, despite functioning correctly in desktop applications like Acrobat Reader or Internet Explorer.
Ensure your mobile device has a default email application installed and properly configured, as any mobile document sharing relies on the system's native email client.
Use the Native Mobile Share Function
Since mobile PDF readers often block or do not support interactive submit actions, you can bypass the broken button by using the app's built-in file sharing feature.
Mobile versions of PDF applications generally have limited support for interactive PDF actions, such as executing JavaScript or triggering Submit Form workflows. To send the document, you must manually share the file using your device's native sharing capabilities.
After filling out the interactive fields in the PDF, tap 'Done' or the checkmark icon in your PDF app to ensure all data is saved locally.
Tap the 'Share' icon (often represented by a square with an upward arrow on iOS, or three connected dots on Android) located in the top or bottom toolbar.
Choose the 'Share a Copy' or 'Send File' option to generate an attachment rather than a generic link.
Select your preferred email application (such as Apple Mail, Gmail, or Outlook) from the share sheet, enter the recipient's address, and tap 'Send'.

Flatten the PDF Before Sending
If the recipient receives a blank form, you may need to flatten the PDF to embed the filled information permanently before sharing.
Fill and Share PDF Forms Easily with WPS Office
WPS Office for mobile devices provides reliable support for viewing and filling interactive PDF forms. If embedded submit buttons fail, WPS Office offers a seamless native sharing feature to email your filled forms instantly without losing data.
- 1. Open the PDF: Launch WPS Office on your mobile device and open your interactive PDF form.
- 2. Fill out the Form: Tap on the interactive text fields to enter your information, then tap 'Save' to retain your changes.
- 3. Share via Email: Tap the 'Share' button at the bottom of the screen, select 'Send File', and choose your email application to send the completed form.

Frequently Asked Questions
Why do interactive PDF features work on desktop but not mobile?
Mobile PDF viewers are designed to be lightweight and fast. To maintain performance and security, mobile apps often strip out or ignore complex JavaScript and specific action triggers, such as email submission workflows, that are standard in heavy desktop applications.
Can I use JavaScript to force the submit button to work on an iPad?
No. Adobe Acrobat Reader for iOS and most other mobile PDF applications do not fully support the execution of JavaScript for automated form submission or launching external email clients directly via scripts.
How can I ensure my clients can submit the PDF forms I send them?
Instead of relying on an embedded submit button, include clear instructions within the PDF document advising mobile users to save their changes and use their PDF app's built-in 'Share' or 'Send File' option to email the form back to you.
