Signing on SignBuddy takes minutes. Everything that makes it secure and legally binding happens automatically in the background.
Drag in any PDF contract. Add fields where signers need to sign, initial, date, or fill in details — or send it as-is.
Add one or many recipients, set the signing order, and choose how each must verify their identity.
Recipients receive a unique, secure signing link by email. No account needed for them to sign.
Once everyone signs, the document is finalized, cryptographically sealed, anchored to the blockchain, and stored with its full audit trail.
The moment a signature lands, SignBuddy turns it into durable evidence.
The signer's identity is confirmed via email, OTP, or BankID before the signature is accepted.
A SHA-256 fingerprint is taken and a PAdES digital signature is embedded into the PDF.
The fingerprint is published to Sigstore Rekor and timestamped on the Bitcoin blockchain.
Every action — who, when, where, how — is written to an immutable audit log.
No. Recipients sign through a unique, secure link sent to their email — no account or download required.
Yes. SignBuddy signatures are eIDAS-aligned and legally binding across the EU, backed by identity verification and a complete audit trail.
We publish a cryptographic fingerprint of each signed document to public, immutable records (Sigstore Rekor and the Bitcoin blockchain via OpenTimestamps), so anyone can later verify the document hasn't changed.
Yes. You can set the verification level per contract — standard email, email OTP, or Swedish BankID for the highest assurance.
You can set an expiry and automatic reminder schedule. You'll also see real-time status and can resend or cancel at any time.
It takes minutes to get started — and your first 5 contracts each month are free.
