Print, sign, scan, repeat
Today: Print the PDF, hunt for a pen, scan it slightly crooked, attach it, send it back. One signature, half an afternoon.
With Signkoi: They sign on the screen they are already holding, and you get a clean PDF back.
Your recipient never has to sign up
Get it signed. Skip the sign-up.
Upload a PDF, place the fields and send one secure link. Your recipients sign right in their browser — no account, no app, no password — and you get back a sealed PDF with a complete audit trail.

- Signed PDF with audit trail
Why it’s painful today
A signature shouldn’t need a printer — or a password
Getting one page signed is often more work than writing it. Signkoi removes the steps nobody enjoys.
“Create an account to continue”
Today: Plenty of e-signature tools make your client register, confirm an email and learn a new app just to sign one page.
With Signkoi: Your signer opens a link and signs. No account and no app to install.
Lost in the inbox
Today: Signed copies scattered across email threads and chats, and no clear record of who signed, or when.
With Signkoi: Every document sits in one dashboard with its status and a timestamped audit trail.
How it works
From PDF to signed in three steps
Just a document, the people who need to sign it and a few minutes of your time.
- 1
Upload & place fields
Add a PDF up to 25MB, then drop signature, name, date and text fields exactly where they belong.
- 2
Send it for signature
Email it to your signers from Signkoi, or copy a private link and share it any way you like — chat, email or text.
- 3
They sign, you get the PDF
Recipients draw or type a signature in the browser. The sealed PDF and its audit trail are ready straight away.
Features
Everything a signature needs. Nothing it doesn’t.
A focused toolkit that takes a document from upload to signed without detours.
No account to sign
Recipients open the link and sign. No registration and no app to install.
Draw or type a signature
Sign with a finger, stylus or mouse — or type a name and choose from four handwriting styles.
One or many signers
Add several recipients, set a signing order and let reminders follow up for you.
Audit trail
See when the document was sent, opened and signed — every event with a timestamp and IP address.
Sealed, tamper-evident PDF
Signatures are embedded exactly where you placed each field, and the finished PDF is digitally sealed.
Speaks your signers’ language
The app, signing page and emails are available in 12 languages, so everyone signs in a language they understand.
Signs anywhere
Built for the phone already in their hand
Most people open a signing link on whatever device is nearest. The signing page adapts to it — no download, no zooming, no account.
Phone
A full-width signing pad built for thumbs. The page never scrolls away while they draw.
Tablet
Sign with a finger or a stylus on a roomy canvas, in portrait or landscape.
Desktop
Read the full document, then draw with a mouse or simply type a name.
Security & trust
Careful with your documents by default
A signing link is the key to a document, so it is treated like one.
Security
Built so a leaked database can’t sign for you
Hashed link tokens
Every signing link carries a long random token. Links are matched by their SHA-256 hash, and the readable link is kept only in encrypted form.
An audit trail on every document
Sent, opened and signed — each event is recorded with a timestamp and IP address.
You control your sessions
See where your account is signed in and sign out every other session from settings.
Are e-signatures legally valid?
In most countries, yes, for everyday agreements. Laws such as the ESIGN Act in the United States, eIDAS in the European Union and electronic transactions acts from Canada to Singapore recognise electronic signatures.
Some documents — such as wills, certain property deeds or court filings — can have stricter rules.
General information, not legal advice. Check the rules that apply to your document and jurisdiction.
