Lines are a great way to annotate, comment and markup PDFs and documents. They can leave helpful reminders to yourself or others, and make working with, or taking notes on, PDFs more efficient.

But how do you draw lines on PDF documents?

We'll show you multiple methods to draw or add lines to PDFs.

Keep in mind that PDF readers such as Adobe Acrobat Reader, or your default browser PDF viewers like Edge and Chrome, can not draw line or add lines to PDFs. You'll need a PDF writer or annotation tool.

If you don't have any such tools, we'll show you an alternative to Adobe's expensive PDF tools, as well as 2 free methods for drawing lines on your PDF documents.

How to Customize Your Lines

There are different line properties you can adjust and customize when adding or drawing lines on a PDF document.

  • Width/Thickness - how thin or thick your line is
  • Color - the color of your line
  • Pattern - (Solid line, Dotted , Dashed, or Dotted & Dashed lines)
  • Transparency - if you want your line to be see-through
  • Start/End - what you want on the end of your line (arrows, circles, triangles, etc.)
  • Fill color - the color of the shapes at the Start/End of your line

Annotations and Markup Using Lines

You have many options when using line to annotate, markup, or add comments to your PDF documents. You can either you the Shapes tool to add straight lines (easier method), or you can draw freehand lines on your documents with the Pen tool.

Shapes Tool (Best for straight lines)

This is the easiest way to draw lines on PDF documents, especially straight lines. Easily annotate and markup PDF documents with lines; and the lines are easily customizable.

Pencil Tool (Best for drawing lines freehand)

If you need to draw lines that may not be straight, or prefer to have more control over your line markup on your PDF documents, then you can use the Pencil tool. You can still adjust the color and thickness of lines drawn with the Pencil tool. Sky's the limit with this tool, although straight lines may be more difficult to get right.
