The tabs you always have open
Every developer has a handful of little utilities they reach for several times a day. Here they are in one place, without the ads-every-three-lines clutter of the usual sites, and without sending your data anywhere. Paste in an API response with real customer data and it never leaves your machine.
- JSON Formatter & Validator pretty-prints, minifies and finds the exact line of an error.
- Base64 Encode / Decode handles text, files and JWT payloads.
- URL Encode / Decode also breaks a link into its parameters.
- HTML Entity Encoder escapes code samples and fixes double-encoded text.
- Color Converter gives HEX, RGB, HSL and CMYK, plus a WCAG contrast check.
- CSS / JS / HTML Minifier strips comments and whitespace safely.
- HTML Table Generator turns spreadsheet cells into clean markup.
- Meta Tag Generator writes SEO, Open Graph and Twitter tags with a Google preview.
A typical workflow
Build a page, generate its tables and meta tags, check your colors for contrast, escape any code samples and minify the result before it goes live. Along the way you can validate the JSON your scripts use, decode a token, and look at what's inside a tracking link.
