Draw your signature — or type it

Sign with your finger or mouse on the signature pad — strokes are smoothed so it looks like ink, not a jagged line. Prefer typing? Switch to the Type tab and your name is rendered in a handwriting-leaning italic. Then tap the page preview exactly where the signature should sit.

Your contract never leaves your browser

Contracts, leases, and NDAs are exactly the files you do not want on someone else’s server. nopa stamps the signature in your browser — no upload, no account, no watermark on the result.

Honest limits: a visual signature

This tool places an image of your signature on the page — like printing, signing, and scanning, minus the printer. It does not add a cryptographic certificate. If you need a qualified e-signature with legal certification, use an accredited provider.
