⚡ Quick Tools
Encode / Decode / Hash
Base64, URL encoding, Hex, HTML entities, and cryptographic hashing (MD5, SHA-1, SHA-256, SHA-512) — all client-side, nothing leaves your browser.
💡 Tip: paste a JWT, HTTP Basic Auth header, or cookie value to quickly decode it.
COMPONENT encode (encodeURIComponent)
FULL URL encode (encodeURI)
HTML Entity Encode / Decode
💡 Use for XSS payload analysis and sanitization testing.
Cryptographic Hash Generator
⚠ MD5 and SHA-1 are cryptographically broken — use SHA-256+ for security purposes.
