You need to add lines to a PDF or markup a PDF by drawing lines, and you don’t know how? This online tool will help you draw on a PDF file freehand or by adding shapes.

PDFs are an excellent document format to use for receiving and sending information online. The PDF is particularly useful if you’re editing a document for someone and want to notate that changes need to be made to a document. For this reason, you may be wondering if you can draw on a PDF and how to do so. Drawing on a PDF may not be possible with some PDF readers.

To draw on a PDF, you’ll need to use a PDF editor. PDF.Live’s online editor lets you make edits entirely in your browser. You don’t need to download and install special software. We’ll show how you can draw, make lines, and otherwise mark up a PDF as you see fit entirely online using the PDF.Live editor.

Before you begin, you’ll need to convert your PDF to an editable PDF. This is very simple: Just drag and drop your PDF into the editor or click Select File to Edit and navigate to the PDF in your file browser.

Once you’ve uploaded your PDF, select Edit PDF to get started.

Tips for Using PDF Drawing Markup Tools

To draw on a PDF, in the PDF.Live toolbar, click the Draw option. This will turn your cursor into a + sign. 

You’ll see a few different formatting options for your PDF drawing. 

• The Weight changes the thickness of your drawing
• The Opacity affects how transparent your drawing is
• The Color changes the color of your drawing
• Erase removes existing drawings that you’ve made

This drawing won’t be constrained to straight lines or angles. It’s a free draw, which means it will take on whatever shape you draw.

For drawing Straight Lines, navigate to the Shapes tab on the toolbar and select the Line tool. 

Line tool: Allows you to create a single straight line

Curve tool: Lets you make a curved line by clicking two points and then dragging to adjust the angle of the curve. 

Upon selecting one of these options, you’ll then be prompted to draw a line on your PDF wherever you choose. You can also create shapes in this section by selecting the Square, Polygon, or Circle tools. 

Much like the freehand draw tool, these tools change your cursor to a + sign, which lets you click and drag anywhere in your PDF to create a shape to your sizing specifications. 

As with the draw tool, you can change the formatting settings of your shapes on the toolbar. You can also adjust the opacity of the shape if you want a transparent highlight effect. Or, you can remove the fill altogether for a hollow box to better call out a section of a PDF. 

You can use the shape tool alongside the freehand draw tool to make more nuanced edits or drawings in your PDFs. 

We’ll also point out the Eraser (E) tool, which lets you remove any shapes or drawings that you’ve created. 

Consider trying out PDF.Live’s powerful editor tool today to draw on a PDF and more. Select “Start Free Trial” and simplify your PDF workflow.

Draw a PDF Arrow or Line

If you’re annotating or editing a PDF, it’s often useful to be able to point to specific areas of text or images. Arrows or lines can help you make these more nuanced annotations or signifiers on a document.

Whatever your use case, inserting an arrow or line in a PDF has never been easier than with PDF.Live’s online editor. This editor has a lot of functions for drawing shapes and annotating documents. However, for the purposes of this tutorial, we’ll be focusing on how you can add arrows and lines to any PDF you’re working on.

1. Upload your PDF to the PDF.Live Editor.

Simply drag and drop your PDF into the editor or click Select File to Edit and navigate to where your PDF is located on your computer. Once you’ve uploaded your PDF, click Edit PDF to open the PDF.Live editor and start editing your PDF.

2. In the PDF.Live editor toolbar, select the Shapes tab.

PDF.Live’s many editing options are found on this toolbar.

3. For drawing arrows and lines, select the Shape dropdown and select the arrow. 

Here you’ll see the many shapes and figures that PDF.Live’s editor allows you to make. You’ll notice that this toolbar also contains options to customize the style of your shape. Change the color of the shape, its weight, and whether it’s filled with color (this will not apply to arrows and lines). 

4. Select the arrow or line icon and draw an arrow or line on your PDF.

Upon selecting Arrow or Line, your cursor will turn into a + sign, signifying that it’s in drawing mode. From here, you can click anywhere in your PDF to mark a starting point for your arrow. Then, hold down to click and drag your cursor to where you’d like the arrow to point to. Release your click when the arrow is pointing to the correct place. Remember: Where you release your left mouse button will be where the arrow is pointing. 

To change the beginning, end, direction or length of the arrow, select the Move hand and click the arrow to begin adjusting it.

Adding Custom Arrows & Lines in PDFs 

Once you’ve created a line or arrow, you can change its location by clicking it and dragging it anywhere that you want it to be located. You can rotate it by pressing the circular arrow to the right of the shape and dragging it. It will rotate around a fixed axis in the middle of the shape. 

To change the color, shape, or other formatting settings, click your shape and then adjust the formatting settings on the toolbar at the top of the PDF.Live editor. Once you’ve made your changes, click off of your shape, and you’ll see them apply. 

Here, you’ll be able to change how your arrows and lines appear. For example, you can choose a multitude of preset colors for your line. You can also make your own custom colors here. Alternatively, you can change the stroke size of the arrow or line.

To remove existing lines, either click the Trash Can icon next to the line or select the Erase option under Shapes and click and drag over the area you want to erase. 

Try experimenting by drawing arrows and lines of your own on a PDF and changing around the formatting settings!

Drawing Custom Shapes with PDF.Live’s Editor

There are endless possibilities to how you edit your PDFs using PDF.Live’s editor. This extends to creating shapes, as the PDF.Live editor allows you to draw free-form shapes. With the editor, you can draw a few preset shapes on a PDF — circle, square, polygon, etc. — and you can draw custom shapes on any PDF.

1. Upload your PDF to the PDF.Live editor.

You can either drag and drop your PDF to upload it, or click Select File and navigate to where your PDF is located on your computer. Once you’ve uploaded your PDF, click Continue to open the PDF.Live editor and get started.

2. In the PDF.Live toolbar, select Shapes to add a shape to your PDF.

The Shapes panel will open at the top of the PDF.Live editor, which allows you to create a number of different shapes in your PDF. 

Your cursor will then turn into a plus sign, signifying that you can start drawing your shape anywhere on your PDF. By default, you’ll be drawing a rectangle. 

To do this, hold down your left-click button and drag your mouse to start drawing a shape. Once you’ve made your shape, you can select the Pan tool that looks like a hand or simply click the shape you’ve created to reposition it. You’ll be able to see if you have the shape selected if it has multiple blue circles around the perimeter and the toolbar underneath.

The Toolbar allows you to change the formatting settings of your shape. If you want to change the shape’s color or add an internal fill, you can do so from here. You’re also able to change the thickness or erase the shape entirely. 

3. For other free-form but preset shapes, check out some other icons within the Shapes tab. 

For the purposes of this tutorial, we’ll be focusing on the Polygon and Polyline functions. These tools allow you to draw multiple straight lines within a single shape. The rectangle that we drew before was fine, but with the polygon function, we’ll be able to create more complex shapes.settings to change how your shapes appear on your PDF.

Select Polygon and click anywhere in your PDF. A line will then be anchored to that point. From there, you can click somewhere else in your PDF to create an endpoint for that line. You’ll see a line appear between the anchor and your mouse cursor, so you know what the line will look like.

Once you’re drawing the final line within your shape, attach it to the beginning of your shape, which is marked by the outlined box. You can also double-click at any time to have the polygon tool automatically attach a line from the beginning of your shape to the final line you’ve drawn. 

Try experimenting by making shapes of your own on your PDF! Try adjusting the formatting settings to change how your shapes appear on your PDF.
