How to Sign a PDF Online Without Downloading Software

July 30, 2025

Need to sign a document urgently but don't have a printer or scanner? No problem. Signing a PDF electronically is fast, legally binding, and can be done for free without installing any software. Here’s how you can do it in under a minute.

The Old Way vs. The New Way

Traditionally, signing a PDF meant printing it, signing with a pen, scanning it, and emailing it back. This process is slow and requires hardware. The new way? Use a free online PDF editor like Docento.app that runs entirely in your web browser.

Creating Your Digital Signature

Most online tools give you three easy ways to create a signature:

  1. Draw: Use your mouse or trackpad to draw your signature directly on the screen. It feels natural and looks authentic.
  2. Type: Simply type your name, and the tool will convert it into a variety of professional-looking signature fonts.
  3. Upload: Already have a signature image? Just upload it from your computer and place it on the document.

Placing and Saving Your Signature

Once you've created your signature, click on the document where you want it to appear. You can resize and reposition it as needed. After you're satisfied, click the "Export" button to download your signed PDF. It’s that simple, secure, and fast.
