How to add digital/electronic signature to PDF

Last updated on August 6, 2018 by

Wondering how to add a signature to PDF? There are various reasons why people may need to sign a PDF document. First of all, those who deal with clients who are thousands of miles away may sometimes have to send PDF electronic forms with their corresponding signature. A digital signature helps secure and authenticate documents.

And if you’re a business traveler who has to sign documents that are in PDF format, you may need some useful tools that will help you add your signature without having to access a scanner or print out the form.

If you’re looking for the easiest ways to add signatures to PDF, check out these three handy tools.

Method 1: Online PDF signature software – RightSignature

RightSignature is a browser-based application that lets you sign a document without signing up. You just have to provide an email address to receive the output. It has a signature pad, and it also has an iPhone functionality so you can make your signature with your mobile device.

To send out a PDF document for signing, you have to upload your PDF file, enter the email and name of the recipient/s, and type the subject and message of the document.

However, the main disadvantage of this tool is the very limited free trial. You can only have five documents signed, and then you’ll have to pay to continue using it.

Method 2: Adobe Photoshop + Adobe Acrobat to sign a PDF document using your signature

Using these two Adobe programs, you can create an image of your signature and use it as a digital stamp. Follow the steps below to add digital signature to PDF:


Sign a clean, white paper, and scan it. Save the document as a TIFF image file.



Open the saved image file in Adobe Photoshop. Start cropping the image to fit your signature properly. You may use eraser tools like the Magic Eraser to erase any blotches and to get rid of the white background.


Save the image as a “Photoshop PDF” file type after saving it in your desired file location. Click “PDF Options> JPEG > Save Transparency> Image Interpolation”. Then save it again.


Make a custom stamp using Adobe Acrobat. You can do this by clicking “Tools > Comment and Markup > Stamps > Show Stamps Palette > Import”. Find the image file that you saved locally, select it, and name your new stamp.


Finally, open your PDF file, and use the stamp tool to add your customized stamp to the document. Don’t forget to save it afterwards.
