How to Restore 100% Opacity for Adobe Acrobat Comment Text
Question details
The user needs to restore the default appearance of text comments in a PDF so that they are fully opaque rather than semi-transparent.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Adding new text comments or annotations to a PDF document.
- Observed behavior
- Newly placed text comments appear at about 50% opacity after typing is finished, even though they look fully opaque while being typed.
Ensure you have the Comments pane enabled in Adobe Acrobat and have at least one PDF document open so you can access the annotation properties.
Set Default Properties Using an Existing Opaque Comment
This is the most straightforward method if you have another document or an older comment that already displays at full 100% opacity.
By borrowing the formatting from an unaffected comment, you can force Acrobat to use those correct settings for all future text comments.
Close your current documents and open a PDF file that already contains text comments with full 100% opacity.
Open the Comments pane, find the fully opaque comment, and right-click on it. Select 'Properties' from the context menu.
In the Properties dialog box, check the option that says 'Make Properties Default' (or 'Make Current Properties Default'), then save the document.

Restore Opacity via Acrobat JavaScript Console
Use this method if you cannot find an existing fully opaque comment to copy properties from.
Add Clear and Opaque Comments Easily with WPS PDF
Avoid unexpected opacity changes and formatting bugs by using WPS Office. WPS PDF provides a robust set of commenting and annotation tools that are lightweight, highly intuitive, and ensure your text always displays exactly as intended.
- 1. Open PDF in WPS Office: Launch WPS Office and open your PDF document using the built-in PDF viewer.
- 2. Navigate to Comment Tools: Click on the 'Comment' tab located on the top navigation ribbon.
- 3. Insert a Text Comment: Select the 'Text Comment' tool, click anywhere on your page, and start typing. Your text will remain 100% opaque by default.

Frequently Asked Questions
Why do my Acrobat text comments suddenly become semi-transparent?
This typically occurs when the default appearance settings for annotations are accidentally altered or corrupted, causing Adobe Acrobat to incorrectly apply a 50% opacity setting to all newly placed text comments.
Does the JavaScript console solution work in Adobe Acrobat Reader?
The JavaScript Debugger Console is primarily a feature of Adobe Acrobat Pro and Standard. If you are using Acrobat Reader and cannot access the console, you should use the first method: find an existing fully opaque comment, right-click it, and select Make Properties Default.
Can I change the opacity of multiple PDF comments at once?
Yes. You can select multiple comments simultaneously in the Comments pane by holding down the Shift or Ctrl key. Once selected, right-click, choose Properties, and adjust the opacity slider to 100% for all of them at once.
