Free Online HTML Entity Encoder & Decoder Tool
ToolVixo’s HTML Entity Encoder & Decoder is an essential utility for web developers, content editors, and technical writers. HTML encoding (or escaping) converts special characters that have specific meanings in HTML markup—like the less-than sign (`<`) used for tags—into their corresponding HTML entities (like `<`). This ensures that browsers display these characters as text instead of interpreting them as code. This tool also reverses the process, decoding HTML entities back into their readable character forms.

Why Use an HTML Entity Converter?
Using HTML entities is crucial for web security and proper content rendering. Failing to escape special characters can lead to broken HTML layouts or expose your website to Cross-Site Scripting (XSS) vulnerabilities if user input is displayed directly. This tool helps you quickly prepare text for safe insertion into HTML documents or debug existing encoded content.
Common HTML Entity Examples

| > (Greater than) | > | > |
| & (Ampersand) | & | & |
| " (Double Quote) | " | " |
| ' (Single Quote) | ' | ' |
