Professional Developer Utilities
Our comprehensive suite of developer tools streamlines your daily workflow and eliminates repetitive tasks. Whether you're debugging API responses, encoding data for transmission, generating secure credentials, or formatting code for readability, these browser-based utilities deliver instant results without installing anything.
Data formatting and conversion are among the most common developer tasks. Our JSON Formatter validates, beautifies, and minifies JSON data — essential when working with REST APIs or debugging webhook payloads. The Base64 Converter handles encoding and decoding for data transmission, while the URL Encoder/Decoder ensures special characters are properly escaped in query strings and API parameters. For authentication workflows, the JWT Decoder lets you inspect token headers, payloads, and expiration times without external libraries.
Security tools are critical for any modern development workflow. Our Password Generator creates cryptographically strong passwords with customizable length and character sets. The Hash Generator produces MD5, SHA-1, and SHA-256 hashes for data integrity verification. For web developers, the HTML Escaper prevents XSS vulnerabilities by properly encoding user input before rendering.
Every tool runs entirely in your browser using client-side JavaScript — no data is ever sent to a server. This means your API keys, tokens, passwords, and source code remain completely private. Free, instant, and accessible from any device.
