Frequently Asked Questions

HTML Entities are codes used to safely represent reserved or special characters in HTML. For example, '<' is interpreted as the start of an HTML tag, so to display '<' on screen, you use the entity '<'. There are two forms: named entities (&, <) and numeric entities (&, <).

Using characters like < > & " directly in HTML can cause browsers to interpret them as HTML tags or entities, breaking the page layout. Converting to entities ensures browsers treat them as plain text. This is also critical for preventing XSS (Cross-Site Scripting) attacks.

Named entities like &, <, © use readable names for better code readability. Numeric entities like &, <, © use Unicode code points and can represent any character, even those without named entities. Both render identically.

No. Only < > & " are mandatory HTML entity conversions. Regular text (Latin, Korean, numbers) can be used as-is in modern UTF-8 web environments. However, converting non-standard or special symbols is safer for compatibility.

XSS attacks inject malicious scripts into web pages. Converting < > & " ' to entities when outputting user input prevents script tags from executing, displaying them as plain text instead. This is a fundamental server-side security principle.

No. All encoding/decoding is performed client-side in JavaScript. No text is transmitted to any server. The tool works offline and is safe for converting sensitive code or content.

Complete Guide to HTML Entity Conversion

Understanding HTML Entities

HTML Entities are an essential concept in web development. They are a standard format for safely representing special characters in HTML documents, starting with & and ending with ;. The W3C standard defines hundreds of named entities, and numeric entities cover the entire Unicode range. This is fundamental knowledge for web developers, content managers, and email marketers.

HTML Entities in Practice

In real-world web development, HTML entities are used in form input processing, API response rendering, CMS content display, and HTML email creation. Proper entity usage is essential for preventing XSS attacks when handling user input in web applications, where output escaping is mandatory.

Notice

This tool provides general HTML entity conversion. For security purposes, always implement server-side escaping as well. All processing is done in the browser with no server data transmission.
