What are HTML Entities?
HTML entities are a sequence of characters used to represent reserved characters or symbols that cannot be easily typed on a keyboard. For instance, the character < is reserved in HTML to start a tag. To display it literally on a webpage, you must use the entity <.
Why Encoding Matters for Security
Failing to encode user input or code snippets can lead to Cross-Site Scripting (XSS) vulnerabilities. By converting symbols into safe entities, the Heuheu ensures that your data remains data and isn't accidentally executed as malicious code by the visitor's browser.
Local Privacy and Speed
Like every tool in the Junk Drawer, the Entity Alchemist works entirely client-side. Your sensitive code snippets, internal documentation, or private drafts are processed by your browser's own rendering engine. This provides instant results and total privacy, as your input never reaches an external server.
