Download
Get a clean PDF with everything flattened in. Your signature can't be moved or lifted off the page.
Privacy by design
Most e-sign tools keep a copy. We can't.
Typical online signing services upload your document to their servers, often behind an account and a monthly limit.
Vellinko has no server that receives files. Your PDF is read, edited and saved by your own browser, so there is nothing for us to store, leak or sell.

Features
Everything a signature needs
The tools you actually use, without the clutter.
Initial every page
One click adds your initials to the corner of every page. Exactly what a lease asks for, minus the cramp.
Fill in forms
Text fields, checkboxes and dropdowns built into the PDF are detected and ready to fill.
Dates, text & checkmarks
Add today's date, free text, "Read and approved" or a checkmark anywhere on the page.
Remembered on your device
Save your signature to this browser only, so next time it's one tap. Delete it whenever you want.
Works offline
Install Vellinko like an app. After the first visit it runs with no connection at all.
Don't take our word for it
Verify it yourself in 20 seconds
Vellinko's pages carry a strict security policy that blocks them from contacting any outside server. That's not a promise in a privacy policy, it's enforced by your browser.

Legal validity
Straight answers about what you're signing
Vellinko creates a simple electronic signature. Here's what that covers.
Great for everyday documents
Electronic signatures are generally recognized by law, including under eIDAS in the EU and the ESIGN Act and UETA in the US.
- Rental leases between individuals
- Quotes, purchase orders, invoices
- School, internship and permission forms
- NDAs and simple agreements
When to use something stronger
A simple signature doesn't verify who signed. For high-stakes deals, use a provider that checks identity and issues an advanced or qualified signature.
- Real estate sales
- Large loans or financial agreements
- Documents that legally require a notary or qualified signature
FAQ

No. Your PDF is opened and processed by your browser on your device. It is never uploaded, so we never have a copy, not even temporarily.
Is the signature legally valid?
