Free Email Obfuscator & Cloaker
How It Works
- Text Version: Replaces @ and . with [at] and [dot]
- HTML Version: Uses JavaScript to encode and decode the email address
- Provides fallback for users with JavaScript disabled
- Makes it harder for spam bots to harvest the email address
- Keeps the email readable for human visitors
What Is an Email Obfuscator?
An email obfuscator converts your email address into a format that is readable by humans but difficult for automated spam bots to harvest. When you publish your email address on a website, scrapers and bots constantly scan pages looking for the @ symbol pattern. Obfuscating your address makes it much harder for these bots to collect it.
Our free tool offers two protection methods. The text version replaces @ with [at] and dots with [dot], which is simple and works without JavaScript. The HTML version uses Base64 encoding with a JavaScript decoder, so the address only appears in the browser after the page loads — invisible to most scrapers that do not execute JavaScript.
Web developers, bloggers, and small business owners who need to display contact information publicly can use this tool to significantly reduce the amount of spam they receive without hiding their contact details from real visitors.

- Click Obfuscate Email.

- Or copy the HTML Version for stronger JavaScript-based protection.
- Paste the result into your website's HTML where you want the address to appear.
Frequently Asked Questions
Does obfuscation completely stop spam?
No method is 100% effective, but obfuscation significantly reduces harvesting by automated bots. The JavaScript HTML version provides stronger protection than the text version.
Will the obfuscated email still be clickable?
The text version is not clickable — it is for display only. The HTML version renders as a normal email address in the browser and can be made into a mailto link.
What if a visitor has JavaScript disabled?
The HTML version includes a noscript fallback that shows the text version, so visitors without JavaScript still see a readable (though not clickable) version of the address.
