Why is it free and unlimited?
Because processing happens in your browser, not on our servers. We don't pay for expensive infrastructure to process your files — so we don't need to charge you, make you sign up, or cap your usage. No catch: that's literally what the name means.
FAQ
Is this signature legally binding?
This is a simple electronic signature (a hand-drawn image). It does not replace a certificate-based digital signature (like ICP-Brasil) where the law requires that format. If in doubt, confirm the requirement with whoever receives the document.
Can I use a photo of my signature?
Yes. Import a PNG or JPG and choose to apply it with its background or with multiply blending (which removes the white background).
Is the document sent to a server?
No. Signing and saving happen entirely in your browser.
