Before you start

Ensure the PDF you are sending contains actual interactive form fields rather than just a flat image of a form. Advise your recipients to download the file rather than filling it out directly inside their email client or web browser.

Guide Recipients to Use Dedicated PDF Software

Built-in email viewers and web browsers often lack support for interactive PDF form fields. Instructing recipients to download and open the file in dedicated PDF software ensures full functionality.

Many users try to click and type directly within their browser (like Chrome or Safari) or email client preview window. These built-in viewers often flatten the PDF or fail to render interactive fields like checkboxes and text boxes.

1
Add download instructions to your email

When composing your email, explicitly tell the recipient to download and save the attached PDF to their local device first.

2
Recommend dedicated PDF software

Suggest they open the saved file using a dedicated PDF reader rather than double-clicking it if their default app is a web browser.

3
Fill and save the document

Once opened in the correct software, the recipient can fill out the interactive fields, save the changes (Ctrl+S or File > Save), and attach the newly saved file to their reply email.

Mobile Device Compatibility: If recipients are using iPhones or Android devices, remind them to open the attachment using a dedicated PDF app instead of the default iOS or Android mail previewer.

Frequently Asked Questions

Why can't my recipient type into the PDF form I sent?

They are likely opening the PDF in a web browser (like Chrome or Edge) or an email previewer that does not support interactive PDF forms. They need to download the file and open it in a dedicated PDF reader.

Do recipients need to buy expensive software to fill out a PDF?

No, recipients can use free software like WPS PDF or Acrobat Reader to open, fill out, and save interactive forms without needing a premium or paid license.

Can recipients fill out the PDF form on their mobile phones?

Yes, but they must use a dedicated PDF reader app on their iOS or Android device. The default mail app previews often do not properly support form filling.

How do I know if the PDF I'm sending is actually fillable?

Open the PDF yourself in a PDF reader. If you can click into the designated spaces and a typing cursor appears, or if fields highlight when you open the document, it is an interactive fillable form.
