Why password protect your documents?

Confidentiality Protecting documents like contracts, financial sheets, or private letters ensures that only intended recipients with the password can view the content.

Compliance For companies, protecting sensitive user data or internal reports is often a legal requirement under data protection laws like GDPR.

Secure Sharing Even if an email is intercepted or a cloud link is shared accidentally, your data remains encrypted and inaccessible without the key.

Multi-Format Support Most online tools only support PDFs. DocChangify provides full backend encryption for Word, Excel, and PowerPoint files too.
