FAQ

Q. Are my PDFs stored on a server?

A. Only the split and merge tools send an uploaded PDF to the server, but it is deleted immediately after download. The annotation tool does not upload any PDF at all. Everything happens in your browser on your computer.

Q. Why can’t I change the language while editing a PDF?

A. Changing the language opens a new session. Nothing is cached in server memory or on your computer.

Q. How can I sign a PDF?

A. You can add your signature with “Annotate PDFs”.
