Convert raw text and HTML reserved characters into safe, escape-ready HTML entities.
<, >, &, or quotes.The Todoal HTML Encoder is an essential web security and developer utility designed to escape special characters, angle brackets, quotes, and ampersands into safe HTML entities. When rendering user-submitted text inside web pages, displaying code examples, or generating XML/HTML templates, failing to encode special characters leaves your application vulnerable to Cross-Site Scripting (XSS) attacks or causes DOM parsing failures.
Our client-side encoder converts reserved characters into standard HTML entities: < becomes <, > becomes >, & becomes &, " becomes ", and ' becomes '.
Escapes hazardous markup characters into safe entity strings so user text can be rendered securely inside HTML elements and attribute values.
Choose between standard named entity references (<) and decimal numeric codes (<) based on your system requirements.
Instantly copy encoded entity output to your clipboard or trigger encoding with standard developer shortcuts (Ctrl+Enter).
All encoding runs strictly in browser memory. No proprietary source code, user inputs, or database content are ever transmitted over external networks.
Entity encoding is essential for clean web engineering. Reverse entity encoding using our companion HTML Decoder, format HTML markup with the HTML Formatter, preview rendered HTML inside the HTML Previewer, and minify HTML bundles with the HTML Minifier.
For URL and data encoding workflows, encode URL query parameters with the URL Encoder, decode URLs using the URL Decoder, encode Base64 data with the Base64 Encoder, and format JSON payloads with the JSON Formatter. Explore all developer tools in the Developer Tools Suite.
Ensures quotes and ampersands inside HTML attributes (such as value="", title="", or href="") are safely escaped to avoid breaking tag attribute parsing.
Supports escaping non-ASCII symbols, copyright notices, trademark icons, and typographical glyphs into standard named or decimal entity sequences.
Cross-Site Scripting (XSS) occurs when untrusted user input is injected directly into web pages without proper character sanitization. By encoding dangerous characters—such as <, >, &, ", and '—into their safe HTML entity representations, Todoal ensures that user-submitted strings are treated as plain text rather than executable markup, safeguarding your web applications.
Rendering dynamic user input directly into HTML templates without proper encoding introduces critical Cross-Site Scripting (XSS) risks. Todoal replaces reserved HTML syntax characters with named or decimal entity references, guaranteeing that user-submitted content is rendered safely by web browsers without executing arbitrary scripts.
