About HTML Encoding
HTML encoding is the process of replacing special characters with their corresponding HTML entities. Characters like angle brackets, ampersands, and quotation marks have special meaning in HTML, so they must be encoded when you want them to appear as literal text on a web page. Without proper encoding, browsers will interpret these characters as HTML markup, potentially breaking your page layout or creating security vulnerabilities.
HTML encoding is essential for preventing cross-site scripting (XSS) attacks, one of the most common web security vulnerabilities. When user-supplied data is displayed on a web page without encoding, malicious scripts can be injected and executed in other users' browsers. This tool converts all dangerous characters to safe HTML entities, ensuring your content is both secure and correctly displayed.
Frequently Asked Questions
HTML encoding converts special characters like <, >, &, and quotes into their HTML entity equivalents (e.g., <, >, &). This prevents browsers from interpreting them as HTML markup.
Encoding HTML entities prevents cross-site scripting (XSS) attacks and ensures special characters display correctly in web pages rather than being interpreted as HTML tags or attributes.
The most important characters to encode are: < (less than), > (greater than), & (ampersand), " (double quote), and ' (single quote). These characters have special meaning in HTML and can break your markup or create vulnerabilities if left unencoded.
Yes. All encoding and decoding happens entirely in your browser. No data is sent to any server, so your content remains completely private.
