How It Works
URL ENCODER / DECODER performs inspection, decoding, validation, or calculation locally with browser APIs and bounded JavaScript logic. It is designed for safe professional analysis, not exploitation or credential attacks.

Security Notes

Can I use this during client work?
Yes, for legitimate defensive, educational, development, research, and authorized testing workflows.
