1. Do a Quick Web Search: First, just hop onto your browser and type in “free sign PDF online” or “add digital signature to PDF free.” Pick a website that looks secure and easy to use.
2. Find the Signing Tool: Once you’re on the site, look for an option like “Sign PDF” or “Add Signature.”
3. Upload Your PDF: Next, you’ll see a button to upload your PDF file. Click on it and find the document you need to sign on your computer, then select it.  
4. Create Your Signature: You’ll usually get a few options here: you can type your name, draw your signature with your mouse, or even upload a picture of your signature. Choose what works best for you.  
5. Place Your Signature: Once you’ve created your signature, you can usually drag and drop it to the exact spot where it needs to go in the PDF document.
