No longer do signatures require printing out a PDF, getting your handwritten signature on paper, scanning the document again, and then mailing it. Thanks to digital and electronic signatures, you are able to sign any document using your computer or phone in a completely digital way.
When it comes to signing agreements, applications, quotes, authorization letters, and all other kinds of documents, digitally signing a PDF is a great way of saving time and improving document circulation.
In this article, you will find out how to digitally sign a PDF, what the differences between electronic signature and digital signature are, and what should you check before sending a signed document.
What Is a Digital Signature?
A digital signature is a certificate-based means of signing a document which can prove the identity of the signer and help to maintain the integrity of the document.
As opposed to putting an image of a handwritten signature on a PDF file, a certificate-based digital signature utilizes a digital ID and cryptography to prove that the document was not modified after the signing process took place.
Digital signatures have proven to be useful in documents which require authenticity and integrity.
What Is an Electronic Signature?
An electronic signature is a broader term for signing a document electronically.
For example, an electronic signature may involve:
- •Typing your name
- •Drawing your signature
- •Adding an image of your handwritten signature
- •Signing with a mouse, finger, or stylus
The exact requirements for an electronic signature can vary depending on the document, organization, industry, and applicable laws.
Electronic Signature vs. Digital Signature
Although the terms are often used interchangeably, they are not exactly the same.
Electronic signature:
A general method of showing agreement or approval electronically.
Digital signature:
A specific type of electronic signature that uses certificate-based technology to help authenticate the signer and protect document integrity.
The right option depends on what the document requires and the signing standards that apply to your situation.
How to Digitally Sign a PDF
If you have a PDF that needs your signature, you can use a PDF signing tool to add your signature without printing the document.
Step 1: Open the Sign PDF Tool
Open the AziPDF Sign PDF tool and prepare the document you want to sign.
Step 2: Upload Your PDF
Choose the PDF from your device and upload it to the signing tool.
Before signing, make sure you have the correct version of the document.

Depending on the signing options available, you can create your signature by typing it, drawing it, or using an image of your handwritten signature.
Choose the option that best fits your document.
Step 4: Place the Signature
Position your signature in the appropriate location on the PDF.
Make sure it does not cover important text, dates, form fields, or other information.
Step 5: Review the Document
Before finalizing the signature, check the entire document.
Pay particular attention to:
- •Your name
- •Signature position
- •Dates
- •Required fields
- •Document pages
- •Any additional information that needs to be completed
Step 6: Apply the Signature

Step 7: Save Your Signed PDF
Save the completed PDF to your device and keep the signed version for your records.
If you are sending the document to another person or organization, make sure you send the final signed version.
Why Sign a PDF Digitally?
Digital signatures can make everyday work with documents more convenient.
Save Time
There is no need to print out a document in order to sign it. You can do most of the signing procedures using the electronic document itself.
Reduce Paperwork
The documents can be signed and transmitted electronically without the need for printing or scanning.
Access Your Documents from Any Device
Depending on the software you use, you can work with your documents from any computer, tablet, or even mobile phone.
Organize Your Documents Properly
Digital storage of signed documents can be easier to manage and distribute further.
Protect Document Integrity
In the case of certificate-based digital signatures, some information about the signed PDF may help to ensure the integrity of the document.
How to Add a Handwritten Signature to a PDF
If you simply need to place your handwritten signature on a PDF, you can use an electronic signature method.
A typical workflow is:
- Open your PDF.
- Choose the signature option.
- Draw your signature or upload a signature image.
- Place it in the required area.
- Review the document.
- Save the signed PDF.
This can be useful for applications, forms, internal documents, approvals, and other everyday paperwork.
How to Sign a PDF Without Printing It
You don't always need to print a PDF to sign it.
With an online PDF signing tool, you can:
- Upload the PDF.
- Add your electronic signature.
- Position the signature.
- Review the document.
- Save the signed PDF.
This eliminates the print → sign → scan process for documents that only require an electronic signature.
Can I Sign a PDF on My Phone?
Yes. Many PDF signing workflows can be completed from a mobile device.
If your signing tool supports mobile use, you can open the PDF, add your signature using your touchscreen, place it in the correct location, and save the completed document.
For important documents, always review the final PDF before sending it.
Is an Image of a Signature the Same as a Digital Signature?
No.
An image of your handwritten signature is simply an image placed inside a PDF. A certificate-based digital signature uses digital credentials and cryptographic mechanisms to provide additional verification and integrity information.
So, if a recipient specifically asks for a digital signature, check what type of signature or certificate they require before signing.
What Should You Check Before Signing a PDF?
Before applying your signature, take a moment to review the document.
Check:
- •The document is the correct version
- •All required information is completed
- •Your signature is in the correct location
- •The date is correct
- •No important content is covered by the signature
- •You understand what you are signing
- •The recipient's signing requirements have been followed
For documents requiring a certificate-based digital signature, make sure the required digital ID or certificate is available.
