📖 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.
