Encode and decode HTML entities.
The HTML Entity Encoder & Decoder is a developer utility that converts reserved characters, symbols, and Unicode glyphs into standardized HTML entities (e.g., <, >, &) and decodes encoded markup back into readable text. Essential for preventing Cross-Site Scripting (XSS) vulnerabilities, displaying raw code snippets inside HTML documents, and debugging encoded web content, this tool processes text in real time entirely within your browser.
In HTML, characters like <, >, and & have structural syntactic meaning. If untrusted input containing these characters is inserted directly into a page without encoding, browsers may execute malicious scripts, resulting in XSS vulnerabilities.
The five core XML/HTML entities are: < (<), > (>), & (&), " ("), and ' (').
Yes. It decodes named entities (such as © and ) as well as decimal (©) and hexadecimal (©) numeric character references.
No. All encoding and decoding operations take place in your browser memory using native DOM parser APIs, ensuring complete confidentiality.
