Question details
The user wants to eliminate the blue highlight boxes that appear around interactive form fields when viewing a PDF document on an iPad.

- Product
- PDF Viewer
- Device & OS
- iPadOS / iOS
- Scenario
- Viewing or filling out interactive PDF forms on a mobile device such as an iPad.
- Observed behavior
- Blue highlight boxes continuously appear around fillable form fields, which can obscure the document's design or distract the user during presentation or review.
Determine whether the PDF form still needs to be fillable by the recipient. Highlighting behavior is often controlled by the specific PDF viewer app being used on the iPad, and solutions vary based on whether you still need to edit the document.
Make Form Fields Read-Only or Flatten the PDF
Use this method if the form is already completed or only needs to be viewed. Flattening or setting fields to read-only removes the highlights across all viewers.
Interactive PDF forms highlight fillable areas by default to guide users. If the document is ready for distribution and no longer requires input, removing the interactive properties of the fields will permanently eliminate the blue boxes.
Launch your desktop PDF editor, such as Adobe Acrobat or WPS Office, and open the PDF file containing the interactive form.
Select the form fields and access their properties. Check the 'Read Only' option to lock the fields.
Alternatively, use the 'Flatten' feature to permanently merge the interactive fields with the document's background.
Save the modified PDF document and transfer it to your iPad. It will now display cleanly without any blue highlights.

Adjust iPad PDF Viewer Settings
If the form must remain editable, try turning off the form field highlight setting in your specific iPad PDF app.
Easily Manage and Flatten PDF Forms with WPS Office
WPS Office provides a comprehensive suite of PDF tools that allow you to fill, edit, and flatten PDF forms effortlessly. You can easily make form fields read-only before sharing them to iPad users, ensuring a clean and distraction-free viewing experience.
- 1. Open your PDF: Launch WPS Office on your desktop and open your interactive PDF form.
- 2. Navigate to form tools: Go to the 'Form' tab to edit, manage, or review the interactive fields.
- 3. Flatten the file: Use the built-in tools to export or print the file to a flattened PDF, merging all fields.
- 4. Share to iPad: Save the new PDF and share it directly to your iPad for a clean, highlight-free view.

Frequently Asked Questions
Why do PDF forms have a blue highlight on my iPad?
The blue highlight is a default accessibility and usability feature in many PDF viewers. It helps users quickly identify which areas of the document are fillable form fields, especially on touch-based devices.
Can I remove the blue highlighting in the built-in Apple Files app?
Apple's native iOS/iPadOS PDF viewer built into the Files app does not currently have a toggle to disable form field highlighting. You will need to use a third-party app with advanced settings or flatten the PDF first.
Will making a form read-only delete the text I entered?
No. Setting a form field to read-only or flattening the PDF will preserve the text you have already typed into the fields. It simply prevents further editing and removes the interactive blue highlight.
How do I flatten a PDF directly on an iPad?
You can use dedicated PDF editing apps available on the App Store, such as WPS Office, to print the document to PDF or use a specific 'Flatten' tool to permanently merge the form fields with the background document.
