Draw on PDF Online: How to Annotate, Sketch, and Sign Documents Freehand

March 27, 2026

Sometimes, text highlights and comments aren't enough to convey your message. You might need to circle a specific area in a floor plan, draw an arrow toward a chart, or even add a handwritten signature. The Draw on PDF tool gives you the creative freedom of a pen and paper right on your digital screen.

Why Drawing is a Must-Have Feature for Collaboration Creative professionals, architects, and designers often need to provide visual feedback. Instead of writing a long email explaining where a change is needed, you can simply draw a circle or an arrow exactly where it matters. It’s also the perfect tool for digital signing, allowing you to "write" your signature using your mouse or touch-screen stylus.

Features of Our Drawing Tool:

  • Adjustable Brush Size: Whether you need a thin line for writing or a thick one for marking, we’ve got you covered.
  • Eraser Tool: Made a mistake? Use the built-in eraser to clean up your annotations instantly.
  • Color Palette: Choose from a wide range of colors to make your markups stand out.
  • Mobile Friendly: Works smoothly on tablets and smartphones for on-the-go editing.
