Characters: 0 Results never leave your browser.

Why encode and decode URLs?

Keep query strings, API parameters, and special characters valid across browsers by encoding reserved characters such as spaces, ampersands, and Unicode symbols.

  • Prevent broken links: Ensure user-generated text can safely appear in URLs without manual cleanup.
  • Debug faster: Paste encoded query strings and reveal their original values in one click.
  • UTF-8 ready: Handle multilingual content, emoji, and symbols with native encodeURIComponent.

Perfect for SEO & analytics teams

Inspect campaign URLs, decode redirect parameters, or prepare safe values for link tags and JavaScript fetch calls.

Quick tips

  • Encode before sharing URLs with special characters.
  • Decode values that already include % sequences.
  • Use the download button to archive decoded responses for audits.
