Why Sign PDFs in Chrome with SigPDF?

Google Chrome is the world's most popular browser, used by billions of people on desktops, laptops, tablets, and phones. While Chrome has a built-in PDF viewer, it can only display PDFs — it cannot add signatures, fill form fields, or annotate documents. To sign a PDF in Chrome, you traditionally needed to install an extension from the Chrome Web Store, download a desktop application, or upload your document to a cloud-based signing service.

SigPDF eliminates all of that. It is a web application that runs directly in your Chrome browser tab. There is nothing to install, no Chrome extension to manage, and no account to create. Open SigPDF, drop in your PDF, create your signature, place it where you need it, and download the finished document. The entire process takes less than a minute.

Chrome Extensions vs SigPDF

Chrome extensions for PDF signing exist, but they come with significant drawbacks:

  • Privacy concerns — Many Chrome extensions request broad permissions and some upload your PDFs to external servers for processing.
  • Security risks — Extensions can be sold or transferred to new owners who may inject malicious code.
  • Performance impact — Each installed extension adds to Chrome's memory usage and can slow down your browser.
  • Update management — Extensions update automatically, sometimes introducing breaking changes or new permission requests.

SigPDF avoids all of these issues. It is a standard web page that you visit when you need it. Your PDF is processed entirely within your Chrome browser using client-side JavaScript — no data is transmitted to any server.

Complete Privacy in Chrome

When you sign a PDF with SigPDF in Chrome, your document stays on your device at all times. The PDF is loaded into your browser's memory, the signature is applied using client-side JavaScript, and the finished document is generated locally. No file is ever uploaded to SigPDF's servers or any third-party service.
