FAQ

Is it really free?

Are my files stored on a server?

No. The image, PDF and QR tools process files inside your browser and do not send them to a server.

Does it work on my phone?

Most tools work on phones and tablets. Tools that test a device, such as the keyboard or mouse test, need that device connected.
