html entity encode

about this tool

Convert special characters into their HTML entity equivalents for safe display in web pages.

The HTML Entity Encoder converts characters like angle brackets, ampersands, and quotation marks into their corresponding HTML entities. This is essential when you need to display raw HTML code on a web page without the browser interpreting it as actual markup, or when sanitizing user input for safe rendering.

Developers and technical writers use this tool regularly when creating documentation, tutorials, or blog posts that include code examples. Without proper encoding, browsers would render the HTML tags instead of displaying them as text, breaking your layout and potentially introducing security vulnerabilities like cross-site scripting.

The encoder handles the five critical HTML special characters: ampersand becomes &, less-than becomes <, greater-than becomes >, double quotes become ", and single quotes become '. These cover the vast majority of encoding needs for standard web content.

Processing runs entirely in your browser with no server communication. Paste your text or HTML, click encode, and copy the safe output. It works instantly with content of any length, making it a reliable everyday tool for web professionals.
