Questions

Do I need to install anything?

No. It works in Chrome, Safari, Edge and Firefox on any computer or phone. There is nothing to download except your signed PDF.

Will Adobe Reader open the signed file?

Yes. The result is a normal PDF that opens in Adobe Reader, Preview, Chrome and every other PDF app, with your signature in place.

Is my PDF uploaded anywhere?

No. The file is opened, signed and saved inside your browser. It never leaves your device, and the tool keeps working with no internet connection once the page has loaded.

Is a signature added this way legally valid?

In the US, UK, EU and many other places, an electronic signature is valid for most everyday documents, like leases, forms and agreements, when everyone agrees to sign electronically. Some documents, such as wills, may need a witnessed or certified signature, so check if you are unsure.
