Device & OS

Scenario
Distributing and collecting completed forms via email.
Observed behavior
Standard drawing text boxes are converted to images by email clients, rendering the filled content uneditable upon return.
Before you start

Check if the 'text boxes' used in your document are standard drawing shapes (Insert > Text Box) or actual interactive form fields (Developer > Content Controls).

Solution 1Recommended

Use Word Content Controls Instead of Drawing Text Boxes

Replacing standard text boxes with Content Controls ensures email clients treat the fields as interactive text rather than graphics.

Many email clients automatically flatten floating objects, such as drawing text boxes and shapes, into static images to reduce file size and preserve layout. By using Content Controls, you create native form fields that remain editable regardless of how the document is transmitted.

1
Enable the Developer Tab

Go to File > Options > Customize Ribbon. In the right pane, check the box next to 'Developer' and click OK.

2
Remove the Drawing Text Box

Select the problematic text box in your document and press the Delete key to remove it.

3
Insert a Content Control

Place your cursor where the input field should be. Go to the Developer tab and click the 'Plain Text Content Control' or 'Rich Text Content Control' icon in the Controls group.

4
Configure Properties

Click 'Properties' in the Controls group to set a title, tag, or placeholder text for your new form field.

Use Word Content Controls Instead of Drawing Text Boxes

Frequently Asked Questions

Why do email clients change my Word text boxes into pictures?

Many email clients automatically flatten floating objects, like drawing text boxes and shapes, into static images to reduce file size and preserve layout during transmission. Using proper form controls prevents this flattening.

Can I convert a flattened picture back into a text box?

Once a text box is converted to a picture by an email client and saved, you cannot directly convert it back. You will need to recreate the text box or use an OCR (Optical Character Recognition) tool to extract the text.

Does saving the form as a PDF solve the text box issue?

Yes, exporting your Word document as a fillable PDF is a great alternative. PDF format locks the design in place and prevents email clients from altering the elements. However, you must add interactive PDF form fields before sending, which requires a PDF editor like WPS PDF.

Are Word Content Controls compatible with all devices?

Content Controls work reliably on Windows and Mac desktop versions of Office and WPS Office. Mobile viewers might have limited support for form filling, but they typically will not convert the controls into pictures.
