How to Make Text Boxes Transparent with Larger Fonts in Adobe Acrobat
Question details
The user wants to insert text with a larger font size without the text box's default white background obscuring the PDF document underneath.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Adding large text comments or annotations to a PDF document that already contains background images or text.
- Observed behavior
- The Typewriter tool restricts maximum font sizes, while the Add Text Box tool inserts a solid white background fill that covers the underlying PDF content.
Ensure you have the Comment or Drawing Markups toolbar enabled in Adobe Acrobat before attempting to adjust text box properties.
Change Text Box Properties to Make the Background Transparent
Use the Properties menu on the Add Text Box tool to remove the default white fill, allowing you to use larger fonts without hiding the PDF background.
While the Typewriter tool is convenient for basic text, it has limitations on font size. The Add Text Box comment tool allows for much larger fonts, but its default solid background can obscure important parts of your document. By modifying the tool's properties, you can make the background completely transparent.
Navigate to 'Comment' > 'Drawing Markups' > 'Add Text Box' (or select the Text Box tool from the Comment toolbar) and draw a text box on your PDF. Type your desired text and adjust the font size to your preference.
Right-click on the outer border of the newly created text box. From the context menu that appears, select 'Properties'.
In the Properties dialog box, locate the 'Fill Color' option. Click the color swatch and select 'No Color' (usually represented by a white box with a red diagonal line). Click 'OK' to apply the changes and make the text box transparent.

Use WPS PDF to Easily Add Transparent Text Boxes
WPS Office features a comprehensive PDF editor that lets you seamlessly add text without worrying about opaque backgrounds obscuring your document. You can easily adjust text sizes to any dimension you need with a highly intuitive interface.
- 1. Open your PDF in WPS Office: Launch WPS Office and open your PDF document using the built-in WPS PDF editor.
- 2. Insert a Text Box: Go to the 'Insert' or 'Comment' tab on the top ribbon, select 'Text Box', and click anywhere on the document page to place it.
- 3. Customize Font and Background: Type your text and highlight it to adjust the font size from the formatting toolbar. The background is transparent by default, ensuring your PDF content remains perfectly visible.

Frequently Asked Questions
Why does my PDF text box have a white background?
In many PDF editors, including Adobe Acrobat, the default 'Add Text Box' tool includes a white fill color to make text stand out against busy backgrounds. You can remove this by right-clicking the text box, accessing its properties, and setting the fill color to 'No Color'.
How do I increase the font size beyond the dropdown limit in Acrobat?
While the dropdown menu for font sizes may only show options up to 72pt, you can manually select the number inside the font size box, type your desired size (e.g., 150), and press Enter on your keyboard to apply larger fonts.
Can I set all future text boxes to be transparent by default?
Yes. After setting the Fill Color to 'No Color' in the text box Properties menu, simply check the box that says 'Make Properties Default' before clicking OK. All new text boxes you add will now feature a transparent background.
