Features
Everything it takes to get a PDF signed.
Signkoi keeps signing simple: upload a document, drop in the fields, send it to your signers. They sign in their browser and everyone walks away with a sealed PDF and a clear record of what happened.
Preparing documents
Turn any PDF into a document that’s ready to sign
Start with the file you already have. There’s nothing to convert and no template to build first.
Upload PDFs up to 25MB
Contracts, forms, letters, quotes — if it’s a PDF, it works.
Drag fields onto any page
Place signature, initials, name, date, text, checkbox and other fields exactly where they belong, then move or resize them until they line up.
Fields your recipient can’t miss
Each field is clearly marked, so the person signing knows exactly what to fill in and where.
Signing experience
Your recipient taps the link and signs. That’s it.
Asking someone to create an account just to sign one page is how documents get stuck. Signing happens right in the browser.
No account, no app
Recipients don’t sign up or install anything to sign your document.
Draw it or type it
Draw a signature with a finger, stylus or mouse — or type a name and pick from four handwriting styles.
Built for every screen — and every language
The signing page adapts to phones, tablets and desktops, and signers can switch between 12 languages.
Records
A sealed PDF and a clear paper trail
When the last signature lands, you get a finished document — not just a status change — plus a record of how it got there.
Sealed PDF, signatures exactly in place
Signatures are embedded at the precise spots you placed the fields, and the finished PDF is digitally sealed so later changes show.
Audit trail for every document
See when the document was sent, opened and signed, each with a timestamp and IP address, plus a certificate of completion.
A dashboard that keeps score
See what’s waiting, signed or expired at a glance, so nothing slips through.
Find anything fast
Search, filter by status and sort your documents, in a grid or a compact list — whichever you prefer.
