Type or paste into the box, then click Encode or Decode; the result appears in the output box, and an invalid encoding is shown inline instead of failing silently.
URL encoding converts characters like spaces, brackets, and non-ASCII text into a percent-followed-by-hex format that browsers and servers can safely pass in a URL. The Decode button reverses that: paste a percent-encoded string and the tool returns the original readable text.
URL Decoder
Encode text for safe use in a URL, or decode a percent-encoded URL string back to plain text.
Use it to build a query-string value, decode a shared link, or inspect a percent-encoded parameter. Nothing you type is saved; refreshing the page clears the box.
Encoding uses the browser's own encodeURIComponent/decodeURIComponent and runs locally - no upload and no account. An invalid encoding is shown inline as an error message, so you do not have to guess what went wrong.
