E-Signature Workflow — free, private, in your browser

Multi-party signing with a cryptographic audit trail, fully on-device. Unlike iLovePDF or Smallpdf, nothing is uploaded: the processing happens on your own device, so the tool works even with the Wi-Fi off.

  3. 3Each signer signs in turn; download the signed PDF and its certificate

Questions

Are my files uploaded?

No. CommandEditor runs entirely in your browser with WebAssembly — your file never leaves your device. You can verify it: open your browser's network inspector, or switch off Wi-Fi after the page loads; the tool still works.

What makes this different from drawing a signature?

Every signing event is hashed into a tamper-evident audit trail with signer identity and timestamps, and a verification certificate is issued with the document.
