URL Encoder

Encode or decode URL strings and query parameter content securely in-browser.

Browser-first and privacy-conscious
URL Encoder / Decoder
How it works

siteIndex processes input directly in your browser whenever possible, which keeps the tool fast and keeps your data private.

For URL requests, the app validates the address and only allows public HTTP/HTTPS targets before running the check.

Common uses
  • • Debug a website or connection issue
  • • Validate data before sharing or publishing
  • • Prepare content or tokens for technical workflows
FAQ
  • • Is the data stored? No, browser-first tools do not store your content.
  • • What happens with URLs? They are validated before analysis.
  • • Can I use it on mobile? Yes, the interfaces are responsive and touch-friendly.
