How to Add Signature to PDF: Your Complete Guide

PDFs have become essential for sharing and storing all kinds of information, from crucial contracts and agreements to everyday forms. They’re convenient and standardized, but let’s face it, the old-school way of printing the documents, signing them with a pen, and scanning them to store the digital copy is a real pain. It’s slow, inefficient, and creates unnecessary paper clutter.

Luckily, there’s a much better way: adding your signature to a PDF electronically. This not only saves you time and paper, but also boosts security and guarantees your document’s authenticity. In this guide, we’ll explore different methods for adding signatures to PDFs, from simple techniques to advanced digital solutions.

How to Add a Signature to a PDF

1. Using Adobe Acrobat Reader

Adobe Acrobat Reader, the most popular PDF reader out there, has built-in tools for adding signatures. It’s a handy option for most people. Here’s how it works:

Open the PDF: Open the document you need to sign in Adobe Acrobat Reader.
Find “Fill & Sign”: On the right side of the window, you’ll see a tool called “Fill & Sign.” Click it.
Add your signature: Click the “Sign” button. You can type your name, draw your signature with your mouse or a touchscreen, or upload an image of your handwritten signature.
Place and save: Click where you want to put your signature on the document. You can adjust its size and position as needed. Then, save the document to make the signature permanent.

2. Using a Digital Signature Platform

When security and legal compliance are top priorities, consider using a dedicated digital signature platform like Mekari Sign. These platforms offer a more robust and secure way to sign documents electronically. Here’s how to use Mekari Sign:

Upload: Upload your PDF to the Mekari Sign platform.
Add signers: If other people need to sign, enter their email addresses to invite them.
Position signatures: Drag and drop signature boxes onto the document to show where each person should sign.
Send and sign: Send the document to everyone who needs to sign it. They’ll get an email with a link to sign.
Secure signing: Mekari Sign offers different ways to create electronic signatures, like typing, drawing, or uploading an image. Once signed, everyone gets an audit trail as proof of their signature and the document’s integrity. This helps prevent any arguments about whether the signatures are real.

3. Preview (Mac)

If you use a Mac, you have a built-in app called Preview that can handle PDFs. It has a cool feature for creating and adding signatures:

Open the PDF: Open your PDF in Preview.
Show the Markup Toolbar: Click the “Show Markup Toolbar” button (it looks like a little toolbox).
Create a signature: Click the “Sign” button. You can either:
- Use your trackpad: Sign your name with your finger on the trackpad.
- Use your camera: Write your signature on white paper, hold it up to your Mac’s camera, and Preview will capture it.
Add the signature: Once you’ve created a signature, click on the PDF to place it where you want it.

4. Online Tools

Many websites let you add signatures to PDFs for free. These can be helpful, but be careful:

Upload with care: Only use online tools for documents that don’t have very sensitive information. You’re sending your PDF to someone else’s server, so make sure you trust the website.
Features vary: Some tools only let you type your name or upload a signature image. Others might let you draw your signature.
Watch out for watermarks: Some free tools might put watermarks on your PDF. If you need a clean document, find a tool that doesn’t do this, or consider paying for one.

Tips for Adding Signatures to PDFs

Here are some tips to ensure your signed PDFs look professional and are secure:

Legibility: Make sure your signature is clear and easy to read, whether you type it, draw it, or use an image.
Signature size: Adjust your signature’s size so it fits well on the document. It shouldn’t be too big or too small.
Placement: Put your signature in a sensible place, usually at the end of the document or in any signature boxes that are already there.
Security: For important documents, use a digital signature platform with strong security to protect your information.
Document integrity: After signing, double-check that no one has changed the document, especially if it’s important. You can usually do this by checking the digital signature validation.

Choosing the Right Method

The best way to sign a PDF depends on what you need it for and how sensitive the document is. If it’s legally binding or needs to be extra secure, a dedicated digital signature platform like Mekari Sign is the way to go.
