Frequently asked questions
How strong is the encryption?
PDFwise uses AES-256, the strongest standard PDF encryption, powered by the QPDF engine.
What if I forget the password?
There's no way to recover it, so keep it somewhere safe.
Are my files uploaded to a server?
No. All processing happens in your browser on your own device. Your files never leave your computer or phone, which makes PDFwise safe for confidential documents.
