A Signed Document Is Rarely Trivial
By the time you're signing a PDF, it's usually a contract, an agreement, a form with legal or financial consequences — not casual content. Uploading both the document and your signature to an unfamiliar online tool means trusting that service with something that genuinely matters, at exactly the moment it's about to become a binding record.
How This Tool Keeps It Local
This e-Sign PDF tool processes everything using JavaScript inside your own browser tab — neither your document nor your signature is ever uploaded to a server. This is verifiable, not just a stated claim.
- Check the Network tab: open your browser's developer tools, watch the Network panel, and sign a document — you won't see either the file or your signature sent out in a request.
- Disconnect from the internet after the page loads, and use the tool anyway — it still works, since no server round-trip is involved.
Why This Matters Specifically for Signatures
Your signature — drawn or uploaded — is a personally identifying mark you may not want stored indefinitely on a server you don't control, entirely separate from whatever the document itself contains. Client-side processing means neither the document's content nor your signature ever leaves your own device during the signing process.
