Free Developer Tools — Format, Validate, Encode and Test
Every developer keeps a mental list of micro-tasks that interrupt real work: pretty-printing an API response, decoding a Base64 token, testing a regex before it ships, minifying a stylesheet. This category collects those utilities in one fast, bookmark-worthy place — no accounts, no ads in your face, no data leaving your browser for the text-based tools.
The formatters are the daily drivers: the JSON Formatter & Validator beautifies, minifies and pinpoints syntax errors with line numbers; the XML Formatter does the same for XML; the JSON ↔ XML Converter bridges modern APIs and legacy systems in both directions. The encoders — Base64, URL and HTML Entity — cover the three escaping schemes web developers juggle constantly, each with proper UTF-8 handling.
Shipping code? The CSS, JS and HTML minifiers strip comments and whitespace safely — the JS minifier tokenizes your code so strings and regexes survive untouched. The Hash Generator produces MD5, SHA-1, SHA-256, SHA-512 and CRC32 digests for checksums and cache keys, the UUID Generator mints cryptographically random v4 identifiers in bulk, and the Regex Tester gives you live match highlighting with capture-group inspection before your pattern ever reaches production.
