Developer Tools
HTML Entity Encoder/Decoder
Convert special characters to their HTML entities or decode entities back to characters.
About HTML Entities
HTML entities are used to display reserved characters in HTML (like < and >) or characters that don't appear on your keyboard. Encoding converts characters to their entity equivalents (e.g., & becomes &), while decoding does the reverse.
URL Encoder/Decoder
Encode or decode URLs and URL components to ensure proper formatting and transmission.
About URL Encoding
URL encoding converts characters into a format that can be transmitted over the Internet. Spaces become %20, special characters get encoded, etc. This is essential for passing data in URLs, especially in query strings. Decoding reverses this process to get the original text.
JSON Formatter/Validator
Format, validate, and work with JSON data for APIs and configuration files.
About JSON
JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write and easy for machines to parse and generate. It's widely used in web APIs and configuration files. Proper formatting makes it more readable, and validation ensures it's syntactically correct.
XML Formatter/Validator
Format and validate XML data for data exchange and configuration.
About XML
XML (eXtensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It's widely used for data exchange between systems. Proper formatting makes XML more readable, and validation ensures it follows the correct syntax and structure.
CSS Minifier/Unminifier
Minify CSS for production or unminify for development and debugging.
About CSS Minification
CSS minification removes unnecessary characters from CSS code (like whitespace, comments, etc.) without changing functionality. This reduces file size, improving page load times. Unminifying restores the human-readable format for easier editing and debugging.
JavaScript Minifier/Unminifier
Minify JavaScript for production or unminify for development and debugging.
About JavaScript Minification
JavaScript minification removes unnecessary characters from JS code (like whitespace, comments, etc.) and can shorten variable names. This reduces file size significantly, improving page load times. Unminifying attempts to restore the code to a more readable format for debugging.
HTML Minifier/Unminifier
Minify HTML for production or unminify for development and debugging.
About HTML Minification
HTML minification removes unnecessary characters from HTML code (like whitespace, comments, etc.) without changing functionality. This reduces file size, improving page load times. Unminifying restores the human-readable format for easier editing and debugging.
