Encode or decode HTML entities.
HTML Encoder/Decoder runs entirely in your browser. Enable JavaScript to use the interactive tool — your files are processed locally and never uploaded.
HTML Encoder/Decoder is a security and formatting tool that converts special characters (like <, >, and &) into their safe HTML entity equivalents (like <, >, and &), and vice versa. This is crucial for preventing XSS attacks and displaying code snippets safely on web pages.
