What Sign PDF can do
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.

Questions
Is this a certified e-signature?
No — it places a visual signature image; the file never leaves your browser. For most everyday paperwork that is exactly what the other side expects: a signed PDF.
Are my PDFs uploaded?
Processing runs in your browser — your files stay on your device.
Can I sign a PDF on my phone?
Yes — draw the signature with your finger, tap the page, download. The whole flow works with touch.
Can I put the signature on any page?
Yes — every page shows as a preview; tap the exact spot you need. Tapping again moves the signature.
