Questions
Frequently asked
Is SignDoc really free?▾
Yes — completely free, with no hidden costs. Self-signing is free forever. We offer an optional one-time lifetime upgrade for advanced features, and we accept voluntary donations to help keep the service running.
Do I need to create an account?▾
No. There is no account, no login, no registration of any kind. Open the page, upload your PDF, sign it, download it. Done.
Is my document safe?▾
Your PDF is processed entirely inside your browser using JavaScript. It is never sent to our servers. We have no ability to see or store your documents.
What types of documents can I sign?▾
Any PDF document — contracts, agreements, letters, forms, invoices, and more. If it is a PDF, you can sign it.
Can I sign multiple pages in one document?▾
Yes. You can navigate to any page and add a signature independently on each one, positioned exactly where you need it.
Does it work on my phone?▾
Yes. SignDoc works on any device with a modern browser — phone, tablet, laptop, or desktop.
Enjoying SignDoc?
We built SignDoc because document signing shouldn't cost a fortune. It's free, and we want to keep it that way — for everyone. If it saved you time or money today, buying us a coffee helps keep the servers running and the service free. 🙏
Even £1 from you means one more person gets this for free.
