Frequently asked questions
Is my document uploaded to sign it?
No — the PDF is opened and signed entirely in your browser, so it never leaves your device. That makes it safe for sensitive contracts.
Can I use an existing signature image?
Yes — switch to "Upload image" and use a PNG of your signature (a transparent background looks best).
