Frequently Asked Questions
What happens if I forget the password?
For security reasons, ToolEnex does not store your passwords. If you forget it, there is no way for us to recover it. Always keep a backup or use a password manager.
Is this tool safe for financial data?
Yes. Because the processing is local (Client-Side), your sensitive documents are not exposed to the web, making it safer than cloud-based alternatives.
Can anyone open the file without the password?
No. Once encrypted, the document will prompt any PDF viewer (Chrome, Acrobat, Mobile) for the user password before displaying content.
