How to Prevent Acrobat Pencil Markups from Grouping Automatically
Product
Adobe Acrobat Pro DC
Device & OS
not provided
Scenario
Using the Pencil tool for document proofreading or drawing individual freehand annotations.
Observed behavior

Before you start

Make sure you have saved your current PDF progress before modifying annotation preferences or disabling application plug-ins, as restarting the software may be required.

Solution 1Recommended

Review Annotation Preferences and Ungroup Existing Markups

The most common reason for this behavior is overlapping or rapid continuous strokes being treated as a single annotation. You can manually ungroup them and adjust your commenting preferences.

Adobe Acrobat sometimes interprets consecutive Pencil strokes made in the same area as a single connected markup to make moving them easier. If you are doing detailed proofreading, this feature can get in the way.

1
Select the grouped markups

Open the affected PDF in Acrobat Pro DC and choose the Selection tool (the standard arrow icon) from the toolbar.

2
Ungroup the annotations

Right-click on the grouped Pencil markups. If an 'Ungroup' option is available in the context menu, click it to separate the individual marks.

3
Access preferences

Go to Edit > Preferences (on Windows) or Acrobat > Preferences (on Mac), and navigate to the Commenting category in the left pane.

4
Adjust grouping settings

Review the settings to ensure that automatic grouping or continuous drawing features are configured correctly to your liking, then click OK to save changes.

Drawing Speed: Pausing slightly between each stroke can sometimes prevent Acrobat from automatically snapping distinct pencil marks into a single grouped annotation.

Frequently Asked Questions

Why does Adobe Acrobat group my pencil marks together?

Acrobat often groups continuous strokes or strokes made in rapid succession within the same area. This is an intended feature designed to make it easier to move a single complex drawing, but it can hinder edits if you are making distinct proofreading marks.

Can I ungroup annotations in Acrobat once they are grouped?

Yes, you can usually ungroup them. Select the grouped annotation with the Selection tool, right-click, and choose 'Ungroup' from the context menu to separate the individual pencil strokes.

Does the time between pencil strokes affect grouping?

Yes. In many PDF editors including Acrobat, if you draw multiple strokes very quickly without pausing, the software may interpret them as a single connected drawing and group them automatically.

Will flattening the PDF resolve annotation grouping?

No, flattening the PDF will permanently merge all annotations into the background of the document. This means you will not be able to edit, move, or delete the markups at all, whether they are grouped or ungrouped.
