Though most people are used to signing paper documents with a pen, electronic signatures are becoming more common, especially in the following instances:
- Businesses or individuals that provide services often need a signed contract for a project.
- Employers may ask newly hired employees or interviewees to sign a nondisclosure agreement.
- Landlords and tenants both have to sign a lease or rental agreement.
- Companies that rely on online forms to collect information from their users may need signed consent from their respondents.
Did you know
If you’d like to collect e-signatures through online forms (even when you’re offline), Jotform offers robust e-signature widgets along with thousands of form templates!
Signing PDF files may seem daunting, especially if you haven’t done it before. If you’re a first-timer or someone who needs a refresher on how to sign PDF documents, we’ve got your back.
It’s important to understand the difference between electronic signatures and digital signatures. This article discusses the electronic signature, the equivalent of your handwritten signature. It’s merely an image of your signature overlaid on a PDF document.
A digital signature, on the other hand, is cryptographically secure and verifies that someone with your private signing key has seen the document and authorized it. It’s very secure, but also complicated. Digital signatures are the online equivalent to a notarized signature. A trusted third party, known as a certificate authority serves as the notary in terms of verifying your identity.
E-signatures meet automation

Since an electronic signature is what most people expect when they send you a document to sign, we’ll focus on that process. If you’re a Windows user, you’re probably familiar with a PDF reader—an application installed on your PC that allows you to open PDF files (with a .pdf file extension). The most popular option these days is Adobe Acrobat Reader.
We’ll assume that you already have your favorite PDF reader installed on your PC.
Open the PDF file in Adobe Acrobat Reader.
Click the File menu, Open…, and then, select the PDF file you want to sign.
Click on Fill & Sign in the Tools panel on the right.
If you’re not seeing the Tools pane, press SHIFT+F4 on your keyboard.
A toolbar will appear at the top of your document.
Click Sign, and then select Add Signature.
A popup will open, giving you three options—Type, Draw, and Image. Once you’re done, click the Apply button.
Type allows you to type your name in cursive format. You’re free to change the style of the signature.
Draw allows you to draw the signature using your mouse, touchpad, or a stylus if you’re using a touchscreen device.
Image allows you to select an image file of your signature.
Drag, resize and position the signature inside your PDF file.
How to sign a PDF with Jotform Sign
Another popular and easy option to add signatures to your PDF is by using Jotform Sign. And it doesn’t matter what device or operating system you’re using.
Adding signature fields to a PDF with Jotform Sign will only take a couple of minutes, and every document you send out for signatures automatically becomes part of a workflow.
On the My Forms page, click on the Create Form button.
Choose the Create Signable Documents option.
Drag and drop your document into the blue area or click on the Upload Document button. Alternatively, you can upload a demo document to see how Jotform Sign works by clicking on the Try Document button.
In addition, you can upload multiple documents at once. They will be merged into one signable PDF document. You can change the order of files by dragging them using the six dot icon or deleting the unnecessary ones.
Click on the Create Signable Document button.
You can detect fields automatically by clicking on the Detect Fields button at the top of the page. The auto-detect feature uses machine learning to scan your document for potential e-sign fields. Machine learning improves itself with each use, so the more you use auto-detect, the more precise it will get.
Wait for the auto-detector to scan your document, and a banner will pop up asking if you’d like to keep the fields the auto-detector found.
Click the green Keep All button to save those fields, or click Dismiss to discard them and add your own fields to the document.

Seems simple enough.
Excellent but I just need to practice with confidence.

A very good article to read and get the complete information. Electronic signing or digital signing is used in different ways to establish authenticity and non-repudiation. It is performed using long-term and short-term signature certificates with the help of hardware security modules.
Thanks for such a good blog. A digital signature is a mathematical technique used to validate the authenticity and integrity of a message, software or digital document.

How can I add an applicants signature to a pdf that is uploaded in my jotform.
I've created a jotform with questions that need to be answered. When the applicant clicks the submit button it takes them to a pdf that needs to be signed (a signature) for release of the information. Once signed the applicant clicks the submit button and a signed pdf document will be emailed to the client.
Nice blog. A online digital siganture was generated using the PKI method, which produces two keys: public and private. The signer holds the private keys and the recipient uses the public key to decrypt the user identity information during the exchange of information.
