How it works
Three steps: you send, they sign with a verified identity, everyone keeps a PDF that proves itself.
Why choose Sovrasign?

Getting a contract signed shouldn't cost thirty dollars a month, or come with fine print.
Meet Sovrasign: e-signature for freelancers and small businesses, where every signed PDF proves itself.
Upload a PDF, add the people who need to sign, drop in the fields, and send. Done in a few clicks, from your laptop or your phone.
Your clients sign for free, with no account to create. They confirm who they are with the Google, Microsoft or Apple account they already have, or a code sent to their email.
When everyone has signed, the PDF carries its own proof: who signed, how they were verified, and that nothing has changed since. Anyone can check it in our free verifier, and the file never leaves their device.
Cancel any time. Your proof stays with you.
Send your first envelopes free. Plans start at two dollars fifty a month, billed yearly, and you can cancel in two clicks. No surprise bills.

1. Send
- Upload a PDF.
- Add the people who sign, by name and email. They can sign in any order, all at the same time, or one after another in the order you list them.
- Place their fields: signature, initials, date, text and checkboxes.
- Send. Each signer gets an email with their own link.
- Word files (.docx), photos and scans of paper documents, from a computer or a phone.
- Reminders, expiry dates and templates.
When you send, your browser seals the terms into the document: the title, who signs which field, and your own verified identity. From then on, nobody can change them without it showing.
2. Sign with a verified identity
Signers do not need an account, and signing is always free. They open the link, read the document, fill in their fields, and confirm who they are. You never choose how. We pick the way that matches their email address:
| If the signer's address... | They confirm who they are like this |
|---|---|
| Their email belongs to a Google account (Gmail or Google Workspace) | They sign in with Google. |
| Their email belongs to a Microsoft account (Outlook, Hotmail or Microsoft 365) | They sign in with Microsoft. |
| Their email belongs to an Apple account (iCloud) | They sign in with Apple. |
| Any other address (a company mail server, GMX, Yahoo, Proton...) | We email them a one-time code. |
Every signer confirms who they are; signing by just clicking a link is not offered. A one-time email code is the minimum, and the document records which way each person used, so a reader can see how strong each confirmation was.
The signature itself is made in the signer's browser, with a key created for that one signature and thrown away afterwards. Only the signer's addition is uploaded. Our server then checks the whole document again before it accepts it.
Extra checks for sensitive documents, such as a code by text message, an ID document check, a qualified signature in the EU or a notary in the US, come later as paid options. Coming
3. Keep a PDF that proves itself
When everyone has signed, each person receives the signed PDF by email. It is an ordinary PDF that opens anywhere, and it carries its own evidence:
- the document as it was sent, and the terms the sender sealed;
- one signed layer per person, in the order they acted;
- each signer's identity, as confirmed by Google, Microsoft, Apple or the email code;
- a record of every step, each entry linked to the one before, so none can be removed or reordered.
Anyone can check it with the verifier, without uploading it and without an account with us. The evidence stays valid even if your account, or Sovrasign itself, no longer exists.
Trusted timestamps from an independent time-stamping service: one per signature on paid plans, and one for the whole document on Free, which bounds the times its signers' devices recorded.
