Developer Toolbox
Eleven everyday web tools on one page: minify, format, validate, convert, encode and inspect, with nothing to install and nothing uploaded.
About this tool
This toolbox gathers the small conversions that keep coming back when you build a website: minify or beautify HTML, CSS and JavaScript, format and validate JSON with the line and column of any error, tidy up an SQL query, turn Markdown or BBCode into HTML with a live preview, encode or decode HTML entities and URLs, or strip the tags from a text.
It also helps you understand what you receive: the URL parser splits protocol, host, path and parameters, which you can edit to rebuild the address, and the user agent parser identifies browser, operating system and device type, with your own browser’s string already filled in. JSON, JavaScript and regular expression escaping complete the set. Everything runs in your browser: your code never leaves your device.
