About This Tool
The Client-Side HTML Entity Escape & Unescape utility sanitizes raw markup by converting reserved HTML syntax characters into corresponding character entity references (&, <, >, ", and '), preventing Cross-Site Scripting (XSS) and unintended tag rendering in web templates. Conversely, the unescape mode decodes named and numeric HTML entities back into their raw unicode string equivalents using browser DOM parsing primitives. All string transformations execute locally in memory with zero network latency or server data transit.
How to Use

- 2

- 3
Review the instant transformed string in the output panel.
- 4
Click Copy to transfer the sanitized HTML entity text to your clipboard.
