Why I Built Client-Side PDF Signer
Signing contracts, leases, or administrative forms shouldn’t require creating an account or handing sensitive personal documents over to a cloud SaaS platform. Client-Side PDF Signer renders and modifies PDF binaries directly in your local browser sandbox.
How It Works
- Load Locally: Drop any PDF file onto the canvas. It is parsed in memory using
pdfjs-distwithout any network transmission. - Draw & Position: Sketch your signature on the vector pad, resize it, and place it onto any page.
- Flatten & Download:
pdf-libembeds the signature vector directly into the PDF structure and triggers an immediate local download.
