📖 About PDF Signatures
Adding a signature or stamp to a PDF is a common requirement for contracts, official documents, and approvals. Many tools require expensive subscriptions or upload your sensitive files to external servers.
Our tool processes everything in your browser. Your PDF is decoded using PDF.js and modified using pdf-lib — both are pure JavaScript libraries that run entirely on your device. No data ever leaves your computer.
📖 What Is a PDF Signature Tool?
A PDF signature tool lets you add handwritten signatures, stamps, dates, and text annotations to PDF documents electronically. Essential for signing contracts, approving documents, filling forms, and adding official stamps without printing. Digital signatures save time, paper, and enable remote document workflows.
Draw your signature directly on screen or upload an image. All processing happens locally in your browser — your signed documents and signature image are never transmitted to any server.
