HTML Entity Encoder & Decoder Tool

Our HTML entity converter encodes special characters into their HTML entity equivalents and decodes entity-encoded text back to plain characters, solving the common challenge of safely displaying code and special symbols in web pages. Web developers writing technical blog posts about HTML, CSS, or JavaScript use encoding to display actual code snippets within articles without the browser interpreting the examples as executable markup. Technical documentation authors embed less-than and greater-than symbols in API reference pages by encoding angle brackets that would otherwise create malformed HTML or trigger cross-site scripting filters. Email template developers use HTML entities to ensure that special characters like copyright symbols, trademark signs, and accented letters render correctly across all email clients regardless of character encoding support. Content management system users troubleshooting text display issues decode HTML entities that appear as raw codes rather than intended characters, identifying whether database storage, API transmission, or template rendering introduced the encoding problem. Web scraping scripts parsing HTML content decode entities to recover the original text for natural language processing, search indexing, or data analysis pipelines. The converter supports the complete set of HTML named entities including common characters like ampersand, less-than, greater-than, quotes, non-breaking spaces, and the full range of Unicode code point entities. All encoding and decoding occurs entirely within your browser using JavaScript, guaranteeing that your text content remains private and never transmitted to external servers. Simply enter text and select encode or decode to see the transformed result instantly. Use this conversion tool for technical blogging, API documentation, email development, CMS troubleshooting, and web scraping data cleaning.
