How to Fill and Email Interactive PDF Forms on an iPad
Question details
The user wants to successfully fill out, email, and manage interactive PDF forms on an iPad without the filled data permanently overwriting the blank template.

- Product
- Device & OS
- iPad (iOS)
- Scenario
- Filling out an interactive PDF form and sharing it via email on an iPad.
- Observed behavior
- Advanced features like XFA forms, date pickers, and JavaScript buttons fail to work. Additionally, auto-saving on iOS causes the completed form to overwrite the blank template, preventing it from reverting to a blank state after emailing.
Ensure your iPad is updated to the latest iOS version and that you have a compatible PDF reader installed. It is highly recommended to save a backup copy of your blank PDF form to a secure folder before opening it on your device.
Use Standard AcroForms and Keep a Blank Template
Avoid using incompatible XFA forms and manage iOS auto-save behavior by duplicating a master blank template.
Mobile PDF readers on iOS do not consistently support advanced desktop features such as XFA forms (created with LiveCycle Designer), complex JavaScript buttons, or date pickers. To ensure your form works smoothly, it must be created as a standard AcroForm.
Because iOS apps automatically save document changes as you type, closing or emailing a completed form will not restore it to a blank state. You must manually manage your blank templates.
Using a desktop PDF editor, create your interactive form as a standard Acrobat AcroForm instead of an XFA form. Test all basic fields on your computer.
Transfer the blank PDF form to your iPad via Dropbox, iCloud, or email, and keep it in a designated folder as your untouchable master template.
Before filling out a new form, duplicate the master template file and rename it for the specific user or submission.
Open the duplicated file in your iPad PDF reader, fill out the required fields, and use the app's built-in share icon to email the completed document.

Add a Reset Button to the PDF Form
Try adding a built-in reset button to clear form fields, though JavaScript support on iPad may vary.
Fill and Share PDF Forms Seamlessly with WPS Office
WPS Office provides excellent support for standard interactive PDF forms on mobile devices, including iPads. You can easily fill out forms, duplicate templates, add signatures, and share them directly via email without complex format compatibility issues.
- 1. Install WPS Office: Download and open WPS Office on your iPad from the App Store.
- 2. Open your PDF Form: Navigate to your files or linked cloud storage within WPS Office and open your interactive PDF form.
- 3. Fill out the fields: Tap on the highlighted form fields to enter your text, select dropdown options, or check boxes.
- 4. Share via Email: Tap the 'Share' icon at the top or bottom menu to instantly email the completed form as a PDF attachment.

Frequently Asked Questions
Why do date pickers and JavaScript buttons not work on my iPad PDF form?
Many mobile PDF readers restrict or completely drop support for advanced JavaScript and specialized desktop features. To ensure maximum compatibility on iOS devices, it is best to stick to standard text fields and checkboxes (AcroForms).
Why does my PDF form stay filled out after I email it?
iOS apps are designed to automatically save changes to documents as you type. Once you fill out a form and close or share it, the changes are saved directly to the file. To prevent this, you must make a copy of the blank template before you start typing.
Are XFA forms supported on iPads?
No, XFA forms (typically created with Adobe LiveCycle Designer) are generally not supported by standard mobile PDF readers, including most iPad apps. You will need to recreate the document as a standard PDF form to use it on an iPad.
How can I clear all data from a filled PDF form on an iPad?
If the form was designed with a built-in 'Reset' button and your PDF app supports basic actions, tapping it will clear the fields. Otherwise, you must manually delete the text from each field or simply discard the filled file and start fresh from a blank master template.
