Use Adobe Acrobat to Prepare and Share Fillable Forms

Utilize Acrobat's 'Prepare a Form' and sharing features to generate a secure link for mobile completion.

By utilizing professional PDF editing software, you can convert static documents into interactive forms and distribute them via a direct link. This allows iPhone users to easily access, fill, and return the files.

1
Prepare the Form

Open your PDF in Acrobat, go to the 'Tools' menu, and select 'Prepare Form'. This tool automatically detects form fields or allows you to add text boxes and buttons manually.

2
Share for Review or Signatures

Click on 'Share' in the top right corner. Choose either to 'Send a Link' for general filling or 'Request E-Signatures' if you need legally binding signatures.

3
Complete on iPhone

Recipients will receive the link via email or your chosen online platform. They can open it directly on their iPhone using Safari or a PDF reading app to fill out the form.

4
Return via Email

Once completed, users can tap the configured 'Submit' button or use the iOS share sheet to attach the filled PDF to an email and send it back.

Testing Required: Always test the generated form link on an iPhone yourself to ensure the interactive fields respond correctly to mobile touch inputs before distributing it widely.

Frequently Asked Questions

Can recipients fill out a PDF form on an iPhone without downloading an app?

Yes, modern iOS versions allow users to fill out basic PDF forms directly within the native Safari browser or the built-in Files app without needing third-party software.

How do I add a 'Submit by Email' button to my PDF form?

In your PDF editor (like Acrobat or WPS PDF), you can add a Button field and set its action to 'Submit a form'. Enter 'mailto:your_email@example.com' as the submission URL so it automatically opens the user's email client when tapped.

Why can't my recipients save the filled data on their mobile device?

If recipients are opening the PDF in a basic browser viewer that doesn't fully support interactive PDFs, the data might not save. Advise them to save the file to their device first, or use a dedicated PDF reader app to complete the form.
