100% Browser Sandbox: Secure Developer Utilities
All encoding, formatting, hashing, and regex testing utilities run completely in your client-side browser memory. Your API keys, tokens, SQL queries, and configuration files never touch any servers. This makes our site the perfect developer utility tool suite for security-conscious programmers working with sensitive environment variables, private JSON databases, or client credentials.
JSON Formatter & Validator
Validate, beautify, and minify complex JSON files locally. Spot syntax errors, expand nodes, and format arrays instantly with custom styling controls. If you frequently format nested database configurations or format raw REST API server responses, our browser-first json formatting tool offers colorized output, copy-to-clipboard, and error tracking without passing payloads to external APIs.
Base64 Encoder & Decoder
Convert text or images to Base64 data URLs or decode them back. Ideal for web designers and developers needing quick data encoding without external API calls. Our local base64 decoder helps convert raw bytes or image assets to inline HTML/CSS format directly, ensuring ultra-fast compilation for your frontend projects.
JWT Decoder & Token Inspector
Inspect your JSON Web Tokens (JWT) header, payload, and signature locally. Easily verify expiration times, permissions, and signatures without exposing sensitive payloads. A secure, 100% client-side jwt token checker that decodes HS256/RS256 tokens right in the browser sandbox, preventing sensitive payload leakage.
