Free Developer Tools Online

Whether you are a frontend developer debugging an API response, a backend engineer encoding data, or a designer picking colours — our developer tools are designed to get you an answer in seconds without leaving your browser.

JSON Formatter & Validator

Paste raw, minified, or malformed JSON into the JSON Formatter and get back a cleanly indented, syntax-highlighted, and validated output. Ideal for reading API responses or debugging configuration files. Supports collapse/expand of nested objects.

Encoding & Decoding

The Base64 Encoder/Decoder converts text or files to and from Base64 — commonly needed for embedding images in CSS, encoding API keys, or working with JWT tokens. The URL Encoder/Decoder encodes special characters for safe inclusion in URLs and decodes percent-encoded strings.

Utilities

The Password Generator creates cryptographically random passwords of any length and complexity — uppercase, lowercase, numbers, and symbols. The Color Picker lets you pick any colour and get its HEX, RGB, and HSL values instantly.

All tools run entirely in your browser. No data is ever sent to our servers.
