Learn how to use Pen, Pencil, Brush, Eraser, and Direct Selection tool in Illustrator on the iPad to easily draw and edit your vector artwork.

Take your vector drawing and painting to the next level with Illustrator on the iPad and Apple Pencil. Illustrator's popular drawing and painting tools – Pen, Pencil, Blob Brush, Eraser – will provide you a smooth and precise design experience on the iPad. It's very simple to find and use them – they are available in your left toolbar just like Illustrator on desktop. For details, see Illustrator workspace on the iPad.

Draw and paint

Drawing and painting tools

Draw with Pen tool

  • In the left toolbar, tap the Pen tool ().
  • To create an anchor point, tap on artboard to create corner points or tap and drag to create smooth points. While working with the Pen tool, you can also adjust the handles of a smooth point without changing to a different tool.

Useful tips and tricks

To use the primary touch shortcut, touch and hold the touch shortcut circle. To use the secondary shortcuts, touch and hold the shortcut, then drag your finger or thumb to the outer ring. For more information on the touch shortcuts, see Touch shortcuts and gestures

Here are some handy touch shortcuts that you can use with the Pen tool:

  • Break handle pairing: When drawing with the Pen tool, activate the primary touch shortcut and drag the handles of an anchor point to break the pairing. 
Delete

  • Add and remove points: Tap anywhere on the path to add a point. Long press an existing point to remove it.  You can reposition the new anchor point using secondary modifier.
  • Delete anchor handles: Select the end of a direction handle, then select Delete in the Taskbar on the right to remove the anchor handle.
  • Move a point along a path: To move an anchor point along a path when drawing, enable the secondary touch shortcut (outer circle ring).  
  • Convert corner to a curve: Double-tap on points to convert points from corners to curves and vice versa.

Draw with Pencil tool

  • In the left toolbar, tap the Pencil tool ().
  • To draw a free path, drag the Pencil tool freely on the artboard.
    • If you hold while drawing and then continue from that point, you create a corner point.
    • If you press the primary modifier anytime while drawing with the pencil tool, you create freeform straight-lines.
    • If you press the secondary modifier while drawing with the Pencil tool, you can create straight lines at 45˚ or 90˚.

Set smoothing for Pencil

To set the smoothing of the Pencil tool, tapat the bottom of the toolbar. 

Simply specify a smoothing value or use the slider to choose a value that works the best for you. The minimum smoothing is 0 and maximum is 10, which means smooth curves.

  • Angle: Determines the angle of rotation for the tool. Drag the arrowhead in the preview, or enter a value in the Angle text box.
  • Pressure dynamics: Specify the pressure for your stylus (Apple Pencil) to draw dynamic brush strokes. The thickness of your brush strokes changes according to the pressure you apply on the stylus when drawing your iPad. See also: Manage app preferences.
  • Merge brush strokes: Tap this option to merge the new strokes drawn over existing ones, if they have the same fill color.

Edit with Eraser tool

For quick editing, Eraser tool is available upfront in the toolbar. Tap  to use the Eraser tool. To set the size of the eraser, specify the size in the Eraser size option at the bottom of the toolbar or choose a value using the slider.

Edit path with Direct Selection tool

With the Direct Selection tool, you can easily create angles and curves in your designs or change the path direction.

When you select an anchor point, a contextual widget showing common actions is displayed on the canvas. Tap the following options in this widget to quickly edit the path directly from the canvas. Alternatively, you can tap an anchor point and choose these path editing options from the taskbar.
