Let’s face it—nobody’s got time to print, sign, scan, and send a document anymore. Whether you’re finalizing a contract, onboarding a new hire, or just signing a simple agreement, knowing how to sign a PDF electronically can save you time, stress, and printer ink.
In this guide, we’ll break down everything you need to know—from what it actually means to sign a PDF electronically to how PandaDoc makes the whole signature tool thing a breeze.
How to sign a PDF electronically
There are a few different ways to do this, depending on what tools you already have and what kind of experience and functionality you’re looking for when it comes to document signing (like do you want to be able to do it on your iPhone or Android?).
1. Use built-in tools (like Preview on Mac or Adobe Reader)
If you’re just looking for a quick sign-and-send, your computer might already have what you need.
- Mac users: Open the PDF in Preview, click the markup icon, then the signature icon. Sign with your trackpad or upload an image.
- Windows users: Use Adobe Acrobat Reader (free). Open the file, click “Fill & Sign,” and draw or type your signature.
- 2. Use fillable forms or PDF form fillers
- If your PDF includes interactive fields—like name, date, or signature boxes—you can use fillable form tools to complete and sign it directly in the document without printing or scanning.
- Many PDFs come with built-in fillable fields, but if not, tools like Adobe Acrobat, PDFescape, or online platforms like PandaDoc let you add and fill in fields easily. Just upload your document, complete the form, and add your signature in a few clicks.
- This is a great option if you’re dealing with more than just a simple signature—like applications, contracts, or onboarding paperwork. And yes, most of these tools also work on mobile devices, so you can fill and sign from your iPhone or Android.
3. Try browser extensions (like for Chrome)
Extensions like “Smallpdf” or “DocHub” let you sign PDFs straight from your browser without installing anything bulky.
