MDF | HTML Obfuscator

Protect markup snippets by turning them into an obfuscated script — 100% in your browser

Paste your HTML, click Obfuscate, and get a <script> block ready to embed on your site. Useful for discouraging casual copying, hiding visible markup structure, and sharing snippets with an extra layer of deterrence.

Input HTML

Obfuscated code

Security note: Obfuscation is not encryption or real protection. Anyone with basic knowledge can decode the content. Use this tool as a deterrent against casual copying — not as a substitute for authentication, server-side permissions, or proper security measures.

Why use an HTML obfuscator?

Discourage casual copying

Hide markup structure in the page source, making it harder for someone to grab your HTML with a right-click or a quick glance at the DOM inspector.

Protect designs and widgets

When sharing banners, embedded forms, or promotional blocks, obfuscating the HTML adds an extra step before someone reuses your work without permission.

Deliver ready-to-paste snippets

Generate a single <script> block that's easy to drop into blogs, landing pages, or CMS platforms that block raw HTML but allow embedded scripts.

Reduce visible code clutter

Simplify what appears in the browser inspector when the original HTML is lengthy or contains comments and structures you'd rather not expose openly.

Local privacy

This tool processes everything in your browser. Your code is never sent to a server or stored in external databases.

Fast and no sign-up

No accounts, no artificial limits, no installs. Paste, obfuscate, and copy the result in seconds from any device with a modern browser.

Frequently asked questions

How does the obfuscator work?

Your HTML is encoded in Base64 and wrapped in a script that, when executed, decodes the content and writes it to the page using document.write.

Is it safe to obfuscate sensitive data?

No. Never obfuscate passwords, API keys, tokens, or confidential information. Obfuscation only hides content superficially.

Can I use the output on any website?

Yes, as long as the platform allows <script> tags. Some CMS platforms or editors block scripts for security; in those cases obfuscation won't be applicable.
