Runs in your browser — your file never leaves your deviceFrequently asked questions
Is a drawn signature legally binding?
In most jurisdictions a simple electronic signature like this is legally valid for everyday documents. For contracts with strict formal requirements (deeds, certain real-estate transactions), check what your specific document or counterparty requires.
Can I save my signature to reuse it later?
Not yet — each visit you draw your signature fresh. Since nothing is uploaded, we don't store a signature image between sessions.
Is Sign PDF free to use?
Yes — Sign PDF is completely free with no limits, no watermarks and no sign-up. It runs in your browser, so there is nothing to pay for.
Are my files uploaded or stored anywhere?
No. This tool does all its work locally in your browser using your own device's power. Your files never leave your device and we never see them.
Do I need to install anything or create an account?
No installation and no account needed. Sign PDF works on any modern browser — Windows, Mac, Linux, Android and iPhone.
How do I use Sign PDF?
Open the tool, add your file (or paste your content), adjust any options, then press “Sign PDF”. Your result is ready to download in seconds.
