What this tool is for

URL Encoder Decoder prepares text for URL components and decodes percent-encoded strings back into readable text.

When to use it

Use it for query values, redirect parameters, webhook examples, and copied encoded URLs.

What the result means

Unencoded text becomes percent encoded; percent-encoded text is decoded.

Use notes

  • This uses component encoding, not full URL validation.
  • Spaces become %20.
  • Malformed percent escapes return an error.
