Questions
Are my files uploaded to a server?
No. Everything runs inside your browser, so your files never leave your device. Close the tab and nothing is left behind.
What encryption is used?
AES-256, as defined by the PDF 2.0 standard. All mainstream PDF readers support it.
What if I forget the password?
There is no way to recover it. Keep it somewhere safe, such as a password manager.
