Adobe Acrobat mobile apps for iOS and Android currently do not support certain advanced PDF form actions and JavaScript features. This includes the native Submit Form button utilized for distributed forms. To successfully submit your form data, you must switch to a desktop operating system where the full suite of PDF features is supported.

1
Transfer the PDF file to your computer

Save the unfilled or partially filled PDF form from your mobile device to a cloud storage service like Google Drive, iCloud, or Dropbox, or simply email the file to yourself.

Frequently Asked Questions

Why do custom mailto buttons fail to work in mobile PDFs?

Mobile PDF viewers, including Adobe Acrobat for iOS and Android, are built with lightweight rendering engines that often lack full support for complex JavaScript actions. As a result, custom buttons using 'mailto' scripts will not execute properly on these devices.

Can I use a different mobile app to submit my PDF form?

Most third-party mobile PDF readers also have limited JavaScript and form-submission support. While a few might partially render the buttons, it is highly recommended to use a desktop PDF reader to ensure all form actions execute and send data correctly.

How do I know if a PDF form is distributed?

A distributed PDF form typically contains a purple message bar at the top of the document when opened in a desktop viewer. This bar indicates the document was sent out for data collection and usually features a prominent 'Submit Form' button.

Will I lose my entered data if I start filling the form on my iPhone?

No, you will not lose your data. You can fill out the text fields on your iOS device and save the document. However, you will not be able to submit it via the embedded button until you transfer the saved file to a desktop computer.
