Essential utilities for web developers, backend engineers, and security professionals — all running in your browser with no server uploads. Format JSON from API responses, encode/decode Base64, generate secure cryptographic hashes, create strong passwords, minify JavaScript, and encode HTML entities.

Frequently Asked Questions

Are these tools safe for sensitive data like API keys?

Yes — all processing happens client-side using browser-native JavaScript APIs. Nothing is sent to any server.

Does the JSON formatter validate JSON syntax?

Yes — syntax errors are highlighted with the exact line and character position.

What hashing algorithm should I use for passwords?

For password storage, use bcrypt or Argon2 in your backend — not SHA-256. SHA-256 is for checksums and non-security uses.

Can the JS minifier handle ES6+ code?

Yes — it uses Terser which supports modern JavaScript including arrow functions, template literals, and destructuring.

Can I use Base64 to encode binary files?

Yes — the tool accepts both text input and file uploads, outputting the Base64 representation of binary data.
