Frequently asked questions

Are my files uploaded to a server?

No. Everything is processed inside your browser, and your files never leave your device.

Is this signature legally valid?

It's a digitized handwritten signature, accepted in many private procedures. It doesn't replace an advanced electronic signature or e.firma when the law requires one.

Can I sign several pages?

Yes, turn on "On all pages" and the signature will be placed in the same position on each one.

About this tool

It's useful for signing contracts, forms, liability waivers and permissions without printing or scanning. The signature is inserted as an image inside the PDF.

This is a visual signature (a digitized handwritten signature). It is not an advanced electronic signature or an e.firma/FIEL; for procedures that require a signature with reinforced legal validity, check the institution's requirements.

Because the document is processed in your browser, you can sign confidential files with peace of mind.
