Why do letters turn into %?

An address keeps ASCII letters, digits, and a few marks as they are. Other characters become one %XX for each byte.

May I encode the whole address?

The separators change too. Encode only the value that needs it.

Result

When a search link shows Hangul as %EB%B6%80, you should not have to unpack it by hand.

Encoding a whole address also changes : / ? &, so the result is not a link you can open as it stands.

01How to use it

Choose encode or decode, then paste text or an address. The sample is a starting point.

The result is read-only. Change the input box if you need a different result.

안녕 세계 becomes %EC%95%88%EB%85%95%20%EC%84%B8%EA%B3%84.

The whole sample address becomes https%3A%2F%2Fexample.com%2Fsearch%3Fq%3D%EC%95%88%EB%85%95%20%EC%84%B8%EA%B3%84%26lang%3Dko%26page%3D1.
