How to Electronically Sign a PDF in Under 60 Seconds
You've got a PDF that needs your signature, and you need it done now. Forget the tedious cycle of printing, signing, scanning, and emailing. We'll show you how to add a clean, professional electronic signature to any PDF in less time than it takes to brew a cup of coffee.
Ready? Let's start the clock.
Pick the method that best fits your situation.
Method 1: For Most People (Using the Free Adobe Acrobat Reader)
This is the universal method. If you can open a PDF, you probably have Adobe Reader.
Time Estimate: 45 Seconds
Open the PDF in Adobe Acrobat Reader DC (the free version).
Find the "Fill & Sign" Tool. Look for it in the right-hand tool pane. If you don't see it, click on the "Tools" tab at the top and select Fill & Sign.
Click "Sign yourself". A small toolbar will appear. Click the "Add Signature" button.
Create Your Signature. You have three choices:
Type: Type your name and pick a font style. (Fastest)
Draw: Use your mouse or trackpad to draw your signature. (Most authentic)
Image: Upload a picture of your signature.
Place Your Signature. Your signature will appear as a movable object. Drag it onto the signature line, resize it if needed, and click.
Save the File. Go to File > Save As and save a new version of the PDF. It's now signed and ready to send.
Stop the clock! You're done.
Method 2: For Mac Users (Using the Built-in Preview App)
If you're on a Mac, it's even faster. You don't need to install anything.
Time Estimate: 30 Seconds
Open the PDF in Preview (it's the default app for PDFs on a Mac).
Show the Markup Toolbar. Click the little pen-in-a-circle icon (🖊️) near the top search bar.
Click the Signature Button. It looks like a little signature on a line. Click it and select "Create Signature".
Create Your Signature. You have two amazing options:
Trackpad: Simply sign your name on your trackpad with your finger.
Camera: Sign your name on a white piece of paper and hold it up to your Mac's camera. Preview will digitize it instantly.
Click to Place. Once created, just click the Signature button again, select your saved signature, and click anywhere on the document to place it.
Save. Go to File > Save. Done.
Frequently Asked Questions (The 10-Second Read)
Is this legally binding?
For most everyday purposes (like signing internal forms, expense reports, or simple agreements), yes. This is considered a standard "electronic signature." For highly sensitive legal documents or real estate contracts, the sender may require a more secure digital signature from a service like DocuSign or Adobe Sign.
Can I remove the signature after I save it?
No. Once you save the PDF, the signature is "flattened" into the document, making it part of the file itself. This is a security feature. Always use "Save As" to create a new, signed copy.
What if I need to request a signature from someone else?
For that, you'll want to use a dedicated e-signature service like DocuSign, HelloSign, or Adobe Sign. They manage the entire workflow of sending, signing, and tracking the document.
