What URL encoding is

Make text safe for URLs

URLs reserve characters such as question marks, ampersands, slashes, and equals signs for structure. Percent-encoding turns spaces, Unicode text, and reserved characters into an unambiguous form that can safely travel in a URL.

Common use cases

Prepare and inspect URL values

  • Encode search terms and query parameter values
  • Prepare user text for a path segment
  • Decode URLs copied from logs or analytics
  • Inspect redirects and callback parameters
  • Encode spaces, emoji, and international text
  • Debug malformed percent-encoded values

FAQ

Questions about URL encoding

Does UtilityDock send my URLs to a server?

No. Encoding, decoding, and copying happen locally inside your browser. UtilityDock does not upload or store your input.

What is percent-encoding?

Percent-encoding represents characters with a percent sign followed by their UTF-8 hexadecimal bytes. For example, a space becomes %20.

Should I choose URL component or full URL?

Choose URL component for a query value, path segment, or other individual value. Choose full URL when you want to preserve separators such as ://, /, ?, &, and =.

Does decoding turn plus signs into spaces?

No. This tool follows JavaScript URI encoding rules, where spaces use %20. A literal plus sign remains a plus sign.
