Create an electronic signature for a PDF by adding an image of your signature with a transparent background or by using the Pen tool.

While an electronic signature differs from a digital signature, it's still legally binding and ideal for certain situations like signing a purchase order.

Add an image of your signature

The following steps walk you through adding an image of your signature to a PDF and making the image transparent, so the image doesn't interfere with any information behind it.

For best results, use an image with a white background.
  1. Scan an image of your signature or email one to yourself.
    Don't scan a signature as a PDF. Only image files (.jpg or .png) will work for this process.
  2. Go to Tools > Markup > Image > From File and select the image of your signature from the File Explorer.
  3. Select Open.
  4. Use your mouse to select a point within the document to place your signature, or drag in the document to place and size your signature.
  5. To remove excess space around your signature, go to the Properties panel, select Crop, then drag around the image.
  6. To make the image background transparent, go to the Properties panel and select the Mask Color icon. Select white from the color menu.
  7. Increase the ± tolerance next to Mask Color, so colors close to white will also become transparent. Increase the tolerance until the whole background is transparent.

To save your signature to the Tool Chest so you can use it again, right-click the image and select Add to Tool Chest > My Tools.

Flatten the image before you send your signed PDF. To flatten the image, follow these steps:

  1. Right-click the image.
  2. Select Flatten.

Use the Pen tool

Another way to create an electronic signature is by using the Pen tool. Since it's difficult to write legibly with a mouse, having access to a tablet PC or a pen input device will make creating your signature simpler. Once you've completed your signature, save it to the Tool Chest using the steps above, and you can access it for later use.

In Bluebeam on web and mobile, you can't add a digital signature to a drawing, but you can insert an image of a digital signature from your Tool Chest.
