URL Encoder and Decoder
Percent-encode text for URLs or decode percent-encoded URLs back to readable text. Choose query-value mode for parameters or full-URL mode that leaves ://?&= intact.
What the tool does
URLs can only contain a limited set of characters. Encoding converts the rest, like spaces and accented letters, into %XX sequences. Decoding reverses it.
The two modes
Query value encodes everything, which is what you want for a single parameter value. Full URL keeps the structural characters (: / ? & =) untouched and only encodes the rest.
Worked example
Encoding café au lait as a query value gives caf%C3%A9%20au%20lait. Decoding hello%20world returns hello world.

Frequently asked questions
What is percent-encoding?
A way to represent special characters in URLs as a % sign followed by two hex digits, like %20 for a space. It keeps URLs valid when they contain spaces, Unicode, or reserved characters.
When should I use full-URL mode?
When you have a complete URL and only want to fix the unsafe parts. Query-value mode would also encode the :// and ? characters, breaking the URL structure.
What is the difference between encodeURI and encodeURIComponent?
That is exactly what the two modes do. Full-URL mode behaves like encodeURI (structure preserved); query-value mode behaves like encodeURIComponent (everything encoded).
Is my input sent to a server?
No. Everything runs locally in your browser, so nothing you paste ever leaves your device.
