- Product
- Adobe Acrobat Reader
- Device & OS
- iPad
- Scenario
- Annotating or editing a PDF document using an Apple Pencil on a mobile device.
- Observed behavior
- The mobile app provides a Drawing tool for Apple Pencil, but it only supports freehand strokes without a built-in feature or snap function to draw perfectly straight lines.
Ensure your Apple Pencil is securely paired with your iPad and your Adobe Acrobat Reader app is updated to the latest version to access all available drawing features.
Use the Freehand Drawing Tool for Annotations
Since Adobe Acrobat Reader for iPad currently lacks a dedicated straight-line snapping feature, use the standard Drawing tool to add manual freehand lines.
Adobe Acrobat Reader on iPad is optimized for basic markups and currently does not feature a tool specifically for drawing straight lines or automatically converting rough lines into perfect shapes. You must rely on the manual freehand tool.
Launch the Adobe Acrobat Reader app on your iPad and open the PDF document you wish to annotate.
Tap the blue pencil icon located in the bottom right corner of the screen, then select 'Comment' from the pop-up menu.
Tap the Draw icon (it looks like a pencil) on the top annotation toolbar. You can adjust the stroke color and thickness if needed.
Use your Apple Pencil or finger to carefully draw the line as straight as possible. Tap 'Done' in the top-left corner when finished.

Frequently Asked Questions
Can I hold the Apple Pencil down to snap a straight line in Acrobat?
No. While apps like Apple Notes allow you to draw a line and hold your pencil at the end of the stroke to snap it perfectly straight, Adobe Acrobat Reader on iPad currently does not support this auto-shape gesture.
Does the iPad version of Acrobat have a virtual ruler?
Adobe Acrobat Reader for iPad does not feature a built-in virtual ruler for guiding your Apple Pencil strokes. All drawing annotations are strictly freehand.
How can I underline text with straight lines instead of freehand?
To get perfectly straight lines under text, avoid the Drawing tool. Instead, tap the 'Underline' text tool (the icon showing a 'U' with a line underneath) in the Comment toolbar, then tap and drag over the text you wish to underline.
