HTML Obfuscator & Deobfuscator
Disguise HTML markup with entity encoding and minify, while rendering identically in the browser. This tool obfuscates and deobfuscates HTML on one page — paste your code, pick a mode, and click. Everything runs on your device, nothing is sent to a server.
Everything runs in your browser. Your code is never sent to our servers.
Example
Example Input
<!-- nav --> <div class="hero"> Welcome to our site </div>
Example Output
<div class="hero">Welcome to our site</div>

About the HTML Obfuscator
The HTML Obfuscator disguises your markup two ways: it first compacts it (removing comments and whitespace between tags), then encodes all visible text into hexadecimal entities (e.g. "Hi" becomes Hi). The browser still renders those entities back to their original characters, so the page looks exactly the same to visitors.
This makes it harder for someone reading "View Source" to read the content, copy text, or auto-harvest emails/links with a simple scraper. It is not strong protection — anyone can decode entities — but it is enough to deter casual copying and basic bots.
Deobfuscate mode reverses the process: it decodes all numeric entities back to plain text and then beautifies the HTML structure for readability. Because entity encoding is standard, HTML obfuscated here can be fully restored to a readable form.
FAQ
What's the difference between obfuscating and minifying HTML?
Minifying only shrinks size (removes whitespace/comments) but stays easy to reverse. Obfuscating deliberately makes code HARD to read and reverse-engineer — renaming, disguising strings, and altering flow — while still running the same. For plain beautify/minify, use the Formatter.
Can this obfuscation be reversed?
For HTML, yes — mostly. Hexadecimal entity encoding is standard and fully decodable, so Deobfuscate mode restores the text and re-indents the structure. Whitespace removed between tags during minify is not restored exactly, but the content and readability are recovered.
Is my code sent to a server?
No. HTML is processed entirely in your browser using JavaScript/WebAssembly. Your code never leaves your device.
