Sign a document on this device
Your file is opened, signed and saved here in the browser. Nothing is uploaded.
- PDF, images, text: place signatures, initials, dates and text anywhere on the page.
- Several signers: sign together on one device, or add "Sign here" boxes and pass the PDF along. Each person's signature is sealed separately.
- Word and any other file: signed with a certificate and a detached signature per signer.
- Time-stamped and sealed: every signature carries its date and time, and later changes are detectable.
Signers
Verify a signed file
Check that a file is unchanged since it was signed, and see who signed it and when.
Signing identity
Your signatures are sealed with a private key that is created and kept in this browser. Its key ID lets others confirm that two documents were signed on the same device. Other people who sign on this device get a one-time key for that signing.
Use your own certificate
If you hold a certificate from a certificate authority (.p12 or .pfx), you can sign with it. It is used for this session only and never stored.
