Frequently asked questions

Is this signature legally valid?

It is a handwritten signature image added to the document, which many everyday procedures accept. It is not a certificate-based digital signature; for documents that require one, check the rules that apply in your country.

Is my signature saved?

Only if you choose to remember it in this browser, and you can forget it at any time. It is never sent to our servers.

Are my files stored?

No. This tool processes the file on your device, inside the browser: it is not uploaded to any server and nothing is stored.

Is it free?

Yes. Sign in with your Google account and you get 8 uses per period on the free plan (1 use = 1 downloaded file; if something fails, it doesn't count). catScan Plus, bought in the Android app, is unlimited on the web and in the app.

Does it work on my phone?

Yes. It works in any modern browser on Android, iPhone, Windows, Mac or Linux, with nothing to install. The catScan Android app also lets you scan documents with the camera.
