Private e-signatures, verifiable by anyone
Sign a PDF in your browser — draw or type a signature, place it, and download. Your document is never uploaded.
Nothing is uploaded
The whole thing runs in your browser — open your network tab and watch: your file never leaves your device. Most online tools round-trip your document through their servers.
Verifiable on any device
Add an optional tamper-evident audit trail, and a signature anyone can verify offline at attachkit.com/verify — no account, no callback to us. Most e-sign tools lock verification inside their platform.
