Password Protect Archive

Why password protect archives with Tools Root

Sensitive files sometimes need to travel encrypted, protected by a real password rather than just hidden in a folder. This free tool compresses your files into a genuinely AES-256 encrypted archive directly in the browser.

Real encryption, honestly delivered as .7z

This creates a real, fully encrypted .7z archive, covering both file contents and filenames with AES-256, rather than a "protected" .zip that would still reveal its file listing to anyone who opens it — a distinction verified directly against how each format's encryption actually works before choosing which one to build this around.

A free archive encryption tool with no compromise on protection

Some tools offer weaker legacy ZIP encryption that's known to be crackable, or claim protection while still leaking a file listing. This tool uses genuine, strong AES-256 encryption with full header protection, at no cost and with no file limit.

Common use cases

Encrypting sensitive documents before sending them over email or a file-sharing service, protecting a backup of personal files with a real password, securing financial or legal documents before storage, creating an encrypted archive of confidential work files, or protecting photos or personal records you want to keep genuinely private.

Once you have a password-protected archive, Extract Archive can open it again, provided you enter the correct password in whatever software you use to open it.

Why the archive format matters for real protection

A "password-protected" file only actually protects what it claims to if the underlying format genuinely supports hiding it — the .zip format's own limitations mean a protected zip can still show its full file listing to anyone who opens it, encrypted contents or not. .7z's full header encryption closes that gap, hiding everything, filenames included, until the correct password is entered.

Choosing a strong password

Since genuine AES-256 encryption is effectively unbreakable through brute force with a strong password, the real weak point becomes the password itself — a longer, unique password that isn't reused elsewhere gives the encryption its full intended strength, while a short or common password gives an attacker a much easier target than the encryption algorithm itself.
