How to Remove the Box Around a Line in Adobe Acrobat
Question details
The user wants to remove an unexpected visible box that appears around a line after drawing it in Adobe Acrobat.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Drawing or annotating lines within a PDF document using the built-in drawing tools.
- Observed behavior
- A visible bounding box or border remains around the line after it is drawn, obstructing the view or altering the intended appearance of the document.
Ensure your Adobe Acrobat software is updated to the latest version, as graphical display glitches are often resolved in newer releases. Verify whether the box only appears when the line is actively clicked, which is standard behavior.
Deselect the Line and Check Selection States
The visible box is often just Adobe Acrobat's selection highlight bounding box that appears when an annotation is active or hovered over.
When you draw a shape or a line in Adobe Acrobat, the application keeps the object selected immediately after creation. This selection state is represented by a visible bounding box with sizing handles. This box is not part of the line itself.
Click the 'Hand' tool or the 'Select' tool (arrow icon) in the top toolbar to exit drawing mode.
Click anywhere on a blank space in the PDF document to deselect the active line. The bounding box should disappear.
If the box appears when you hover your mouse over the line, it is simply Acrobat highlighting an interactive element. This box will not print and will not be visible to users merely viewing the document in reading mode.

Adjust Line Fill and Stroke Properties
The drawing tool might have an incorrect fill color applied to its bounding area, causing a solid box to appear around the stroke.
Draw Lines and Edit PDFs Seamlessly with WPS Office
If Adobe Acrobat's bounding boxes are disrupting your workflow, try WPS Office. Its intuitive PDF editor allows you to add lines, shapes, and annotations without frustrating display glitches, offering a smooth and clean reading experience.
- 1. Open your PDF in WPS Office: Launch WPS Office on your computer, click on 'Open', and select the PDF document you want to edit.
- 2. Access Annotation Tools: Navigate to the 'Comment' tab located on the top ribbon menu to reveal the drawing and markup tools.
- 3. Draw Clean Lines: Click the 'Shapes' or 'Line' tool and draw directly on your document. The line will appear cleanly without permanently obstructed bounding boxes once deselected.

Frequently Asked Questions
Why does a blue box appear when I click on a line in my PDF?
This blue box is the selection bounding box indicating that the object is currently active and ready to be moved, resized, or edited. Clicking away from the object will automatically hide the box.
How do I flatten annotations in Adobe Acrobat so boxes never appear?
To prevent boxes from appearing when hovering or clicking, you can flatten the PDF. You can do this by utilizing the 'Print to PDF' feature or by using the Preflight tool, which merges the drawn lines permanently into the background document layer.
Does the bounding box print when I print the PDF?
No, the selection bounding box is simply an on-screen visual aid for editing. It will not appear on the printed copy. Only the actual line and its applied stroke properties will be printed.
How do I change the default color of the lines I draw in Acrobat?
Right-click a drawn line, select Properties, change the color under the Appearance tab, and then check the box that says 'Make Properties Default' before clicking OK. Future lines will now use this color automatically.
