Frequently asked questions

Quick answers about file privacy, processing modes, formats, and device support.

No. All parsing, entity mapping, and encoding/decoding transformations run 100% locally inside your browser memory using pure JavaScript and client-side algorithms. No source code, text, or tokens ever leave your device.
Named entities use human-readable mnemonics (like &amp; for '&' or &copy; for '©'). Decimal entities use the character's unicode decimal value (like &#38;), while Hexadecimal entities use the character's hex code point (like &#x26;). All three formats are fully valid in HTML5 standards.
Encoding HTML entities is crucial for web development to prevent Cross-Site Scripting (XSS) vulnerabilities and render reserved characters (<, >, &, ", ') safely inside HTML documents without being mistaken for markup tags.
No. The decoding engine specifically converts entity sequences (e.g. &lt;div&gt;) directly into their corresponding characters (<div>) without parsing or stripping the surrounding HTML structure.
The 'Essential Only' mode focuses strictly on the 5 primary characters required for secure HTML escaping: ampersand (&), less-than (<), greater-than (>), double quote ("), and single quote (').
Yes. Clicking the 'Swap' button instantly moves the processed output into the input pane and toggles the mode between Encode and Decode for seamless round-trip testing.
