HTML Entities

HTML Entities. Escape or unescape HTML entities, preventing XSS and ensuring proper rendering. Instantly sanitize your web content with our free online HTML entities tool.

This essential web development and security tool allows you to rapidly escape special characters into their corresponding HTML entities to prevent Cross-Site Scripting (XSS) vulnerabilities or unescape them for readable code.

Whether you are a frontend developer fixing broken markup, a security researcher testing input sanitization, or a content editor managing complex character sets, our HTML encoding tool guarantees perfect character mapping.

Simply paste your text to encode or decode it instantly.

This premium text sanitization utility leverages advanced client-side processing to evaluate your character conversions directly within your browser, ensuring that your proprietary source code, sensitive user inputs, and internal documentation are never uploaded to a remote server.

Transmitting raw code to third-party converters poses a privacy risk, but our entirely offline tool eliminates this vulnerability, making secure HTML escaping a 100% private workflow.

We provide a 100% free, private, and secure way to handle HTML entities locally on your device. Related tools: Continue the workflow with URL parser, URL Encoder & Decoder - Percent-Encode Strings for Web URLs, URL / Domain extractor.

How to use this online tool

HTML Entities is designed for fast browser workflows when you need to format, validate, convert, decode, encode, generate, or inspect data without opening a heavy desktop app. Start with the input field or visible options, review the result, then copy or download the output for the next step.

Private processing in your browser

HTML Entities keeps the normal processing step local in your browser. That is useful for code snippets, tokens, documents, configuration values, text samples, and other material that should not be sent to a remote service unless you explicitly choose to share it.

When this tool is useful

Use HTML Entities for repeatable developer tasks, technical documentation, QA checks, quick conversions, debugging, content cleanup, and internal team workflows. The page focuses on clear inputs, immediate feedback, and output that is easy to reuse in code, reports, tickets, emails, or notes.

Practical tips

Before copying the final result, check important details such as spacing, casing, filenames, encoding, token structure, line breaks, or output format. Small checks prevent mistakes when the result is reused in source code, API requests, documentation, spreadsheets, or shared files.
