URL Encoder / Decoder

Percent-encode and decode URLs and query strings.

Runs entirely in your browser. Your data never leaves this device and is never sent to our servers.

Result

URLs may only contain a limited set of characters. Everything else — spaces, ampersands, non-Latin text — has to be percent-encoded, or the URL breaks in ways that are hard to spot. The distinction that trips people up is component versus full URL: encoding a whole URL as a component destroys its structure.

How to use it

Paste the URL or the value you want to encode.
Choose encode or decode.
Leave “Encode as component” on for a single query value; turn it off for a complete URL.

Frequently asked questions

Component or full URL — which do I want?

Component encoding escapes reserved characters like & = ? / so a value can sit safely inside a query string. Full-URL encoding leaves those intact so the URL still works. Use component encoding for values, full for whole URLs.

Why did my + become a space?

In query strings, + is a legacy encoding for a space. If you mean a literal plus, it must be encoded as %2B.
