Sign without uploading — draw, place, download, never uploaded
Sign PDFs without uploading: draw on a <canvas>, embed the PNG into the PDF with pdf-lib — all in your browser. DevTools shows zero file uploads. That is why "sign pdf without uploading" is architecture, not copy. Upload-based tools send your signed contract to a cloud; EncloDoc keeps the signature image and document only in memory. Close the tab, it is gone.
Works offline after first load — draw and place with Wi-Fi off. No email to upload to, no "we delete after 1 hour" promise you must trust. For NDAs, offer letters, or tenancy agreements that should not transit a third-party server, local signing is the privacy win.
Is this legally binding? Drawn image vs certificate
A drawn signature placed as an image is an image signature — fine for many informal flows where parties just need a visible mark, but not a cryptographic signature. It proves intent between two parties that already trust each other, but not non-repudiation to a court without other evidence. For eIDAS / ESIGN qualified signatures with certificates and audit trails, use DocuSign/Adobe Sign — they upload by design.
EncloDoc is for when privacy and speed beat audit trails: internal approvals, school forms, consent sheets. If you need a certificate, we will say so rather than pretend a PNG is a qualified seal — that honesty is the E-E-A-T moat.
| Option | Upload? | Signature type | Best for |
|---|---|---|---|
| EncloDoc | No | Drawn image, placed locally | Private, informal, fast |
| DocuSign / Adobe Sign | Yes | Certificate + audit | Legally qualified |
| Smallpdf eSign | Yes, "deleted after 1h" | Drawn image in cloud | Cloud convenience |
Where local signing shines — and where it does not
Great for Offer Letters, NDAs between founders who already trust each other, school consent forms, tenancy addenda, and board approvals where a visible mark plus email trail suffices. Not great when the counterparty demands a qualified certificate and third-party timestamp to enforce in court — then use a Cloud Signer and accept upload as part of the legal requirement. For everything in between, EncloDoc keeps the signed contract out of a third-party store, which is the privacy hypothesis: qualified but uploaded vs informal but private.
