Fix PDF Submit Form Button Not Working in Adobe Reader for iOS
Question details
The user is unable to use the 'Submit Form' button within an interactive PDF document on an iOS device.

- Product
- Adobe Reader for iOS
- Device & OS
- iOS
- Scenario
- Attempting to submit a filled PDF form via its built-in submit button using the Adobe Reader mobile application.
- Observed behavior
- The Submit Form button does nothing when tapped in Adobe Reader for iOS, even though the same button works correctly on a desktop computer.
Verify that your iOS device has an active internet connection and that the default Mail app is properly configured, as 'mailto' actions rely on these system settings.
Use a Desktop PDF Reader for Form Submission
Since mobile PDF readers lack full support for advanced form actions, opening the file on a desktop computer is the most reliable workaround.
Adobe Reader for iOS and Android does not support all Acrobat form features, including certain 'Submit Form' actions and complex JavaScript operations. Because of these mobile app limitations, buttons tied to 'mailto' addresses or custom submit scripts often fail to execute.
Send or transfer the PDF file from your iOS device to a Windows or Mac computer.
Launch a desktop PDF application, such as WPS Office or Adobe Acrobat, and open the transferred PDF form.
Click on the interactive fields to input your data and complete the required sections.
Click the 'Submit Form' button. The desktop software will successfully process the action or open your default email client with the attached data.

Save and Manually Email the Filled Form on iOS
Bypass the non-functional submit button by saving the completed form and attaching it to an email manually.
Manage and Submit PDF Forms Reliably with WPS Office
Avoid mobile PDF limitations by using WPS Office on your desktop. WPS PDF provides comprehensive tools to view, fill out, and manage interactive PDF forms seamlessly.
- 1. Download the Software: Download and install WPS Office on your Windows or Mac computer.
- 2. Open the PDF: Launch WPS Office, navigate to the PDF tab, and open your interactive PDF form.
- 3. Fill Out Information: Click directly on the form fields to type your information or select options from dropdown menus.
- 4. Submit or Share: Use the document's built-in submit button, or go to 'Menu' > 'Share' to quickly send the completed form via email.

Frequently Asked Questions
Why do PDF form buttons work on Windows but not on iOS?
Desktop applications have full support for complex interactive features, JavaScript, and advanced form actions. In contrast, mobile applications are highly streamlined to save resources and often lack the underlying engines required to process specific interactive commands.
Can I use 'mailto' links in mobile PDF forms?
While simple text-based 'mailto' hyperlinks might work in some mobile apps to open an empty email draft, integrating them into a complex 'Submit Form' action button frequently fails due to the restricted environment of mobile PDF readers.
Is there a way to make PDF submit buttons work on iOS?
Currently, native mobile PDF readers have very limited support for interactive submit buttons. The best workarounds are either saving the filled document and emailing it manually as an attachment, or having the creator design an HTML-based web form instead of a PDF.
