iSharePDFSign an NDA contract locally — no upload
Signing an NDA usually means opening a DocuSign or Adobe Sign link sent by the other party. They upload the contract to their SaaS, you upload your signature, both end up in their database. iSharePDF lets you sign locally instead: drop the NDA into a browser tab, draw your signature with mouse or trackpad, download the signed PDF. Nothing transits a third party.

For ad-hoc NDAs, freelance contracts, vendor agreements and consulting paperwork, the question isn't "do I need a notarized e-signature?" — it's "do I want my contract sitting on DocuSign's, HelloSign's or PandaDoc's servers forever?". Local signing answers that with "no":
- No SaaS audit trail. The signed PDF is the only artifact. There is no platform-side log of your signature event.
- No vendor lock-in. Sending the signed PDF over email behaves like any other PDF — the receiving party doesn't need an account on the signing platform.
- No data-sharing question. The contract content (which may itself be confidential) never touches a third-party processor.
How it works in 4 steps
- Open isharepdf.com/app/tools/sign.
- Drop the NDA PDF. The file loads in-browser.
- Draw your signature with mouse, trackpad, or stylus. Place it on the signature line. Add date and initials if needed.
- Download the signed PDF. Send it back to the other party as you would any other PDF.
Verify it yourself with DevTools
Same protocol as the other tools: F12, Network tab, "Preserve log". Drop the NDA, sign it, download. Zero outbound requests carry the NDA or your signature image. The signature drawing happens on a canvas element; the canvas is flattened into the PDF in memory; the PDF is saved via a blob URL — all client-side.
What this is not
Plain language about edge cases:
- This is a "drawn signature", not a qualified electronic signature (QES). For documents that legally require eIDAS QES level (some real-estate transactions, some banking documents), use a dedicated QES service. For 95% of business NDAs, drawn signatures are accepted.
- No audit trail. If you need the other party to see metadata like "signed at 14:32 from IP 1.2.3.4 by user@example.com", you need a SaaS. iSharePDF intentionally doesn't generate that data.
- Multi-party signing requires email rounds. Each party signs locally, then emails the next party. There is no "Sign here, now your turn" workflow in a browser tab.
For freelancers, consultants and small businesses signing routine NDAs, vendor agreements, and freelance contracts, the local approach is faster, free, and arguably more private than the SaaS alternatives.
FAQ
Is a drawn signature legally binding?
In most jurisdictions (EU eIDAS "simple electronic signature" level, US ESIGN Act), yes — for typical business contracts. A drawn signature is treated equivalently to a wet-ink signature unless the contract type requires a higher level (QES). Check with your lawyer for high-stakes contracts.
How do I prove I signed when?
Add the date next to your signature. For higher-stakes contracts, exchange signed copies over a timestamped channel (email with date headers, or a registered electronic post like AR24 in France). The signed PDF itself doesn't include a server-side timestamp — that's the trade-off for local-only signing.
