html entity encoder/decoder
Safely encode and decode HTML entities to prevent XSS and script injection. Ensure your text displays correctly in browsers. Free and fully client-side.
Pro Tip: HTML encoding converts special characters into their corresponding entities (e.g., < to <), preventing them from being interpreted as code. This is essential for displaying source code or preventing XSS attacks.

1Ever found yourself worrying that a user might accidentally (or intentionally) break your website by typing a '<' or a '>' tag?
Imagine a comment box or a forum where someone could inject a script that steals user cookies—that's a classic 'XSS attack,' and it's a developer's nightmare. Our HTML Entity Encoder is your digital 'sanitizer,' instantly turning those dangerous brackets into safe, readable entities like '<' and '>'. It ensures that whatever your users type remains just text, making your web applications unhackable via code injection.
2Think of this as your website's private 'security filter'—how can I read those messy encoded strings from my database?
Imagine looking at an old database export and seeing a jumble of '&' and '"'—it’s impossible to read or edit. Our 'Decode' feature is like a digital cleaning cloth; with one click, it removes all those entity codes and reveals the clean, original HTML underneath. It’s the fastest way to understand exactly what’s inside a sanitized payload, without the eye-strain of mental decoding.
3Is my privacy protected when I'm sanitizing sensitive code or private documents for my site?
Imagine you're preparing a secure snippet for a critical production service—you definitely wouldn't want that sensitive data floating around on an external server. That's why our HTML Entity tool runs 100% 'client-side.' Every bit of the transformation happens right inside your own browser window. Your data never leaves your computer, providing a secure, local workspace where your information remains strictly private while you get it ready for your website.
