← All Tools
< HTML Entity Encoder
Encode special characters to HTML entities or decode them back.
Why it is useful
It helps prevent markup from being interpreted accidentally and makes examples safe to show in documentation, pages, and code snippets.
How it works
The tool replaces characters such as angle brackets, ampersands, and quotes with entity forms, or reverses those replacements.
Best input
Use snippets of HTML, text, or documentation examples that need to display literally.
Safety tip
Escaping output is only one part of preventing XSS. Use the escaping rules required by your framework and context.
Privacy note
Entity encoding and decoding happens locally in your browser.
Important limitation
This tool is not a complete security sanitizer and does not validate whether HTML is safe to render.
Quick answers
Can this prevent XSS?
It can help display text safely, but real XSS prevention depends on context-aware escaping and trusted frameworks.
When should I decode entities?
Decode when you need to read or transform escaped text, not before rendering untrusted HTML.
