Client-side HTML protection
Protect HTML with or without a password.
Create password-protected self-decrypting HTML files, encode HTML without a password, protect public email addresses, generate .htaccess code, and create strong passwords.

Quick note: Password-protected HTML is useful for lightweight access control. No-password HTML encoding helps hide source from casual viewing, but it is not the same as password protection or server-side security.
Password HTML tool
Password-protect your HTML
Use this tool when you want visitors to enter a password before the HTML page opens. Your source code and password are not sent to a server.
Free web tools
Pick a tool and generate the code you need.
Use no-password HTML encoding, email protection, password pages, .htaccess code, or a secure password generator.
Process
How Code Encryptor works
Designed for quick distribution of private demos, protected HTML notes, and lightweight offline pages.
Derive a key
Your password is processed through PBKDF2 with a random salt to derive an AES key.
Encrypt payload
The HTML is encrypted with AES-GCM and embedded into a self-contained unlock page.
Share the file
Send the generated HTML file and share the password through a separate trusted channel.
Before you publish
Use the right protection for the job.
These tools help with lightweight HTML protection and code generation. For true logins, private records, or sensitive business data, use server-side security.
Password never uploaded
Encryption and code generation run locally in the browser. Your HTML and passwords are not uploaded by this static site.
Use separate password delivery
Do not send the encrypted HTML and its password in the same email, ticket, or chat thread.
Not for sensitive records
Do not use client-side self-decrypting files for regulated records, production credentials, keys, or highly sensitive data.
FAQ
Common questions
Can the password be recovered?
No. The password is not stored by the site. If it is lost, the encrypted file cannot be decrypted through Code Encryptor.
Does this work offline?
Yes. The generated encrypted HTML file contains its own unlock interface and JavaScript. It can be opened locally in modern browsers that support Web Crypto.
Will relative images and CSS still work after unlock?
Usually yes, as long as the decrypted page and its assets are kept in the expected folder structure. This tool encrypts the HTML source, not external asset files.
Can I encrypt JavaScript-heavy pages?
Yes, but test the generated file before sending it. Some scripts may depend on server paths, headers, cookies, or assets that are not included in the encrypted HTML.
Ready
Start with the right HTML protection option.
Use password protection when visitors must unlock the page. Use no-password encryption when you only want to hide the HTML source from casual viewing.
