A worked example
Encode a Korean search term
- Start with
- URL encode · 한글 검색
- Check the result
- %ED%95%9C%EA%B8%80%20%EA%B2%80%EC%83%89
The space becomes %20. URL decode turns the result back into 한글 검색.

URL & Base64 Encoder
Percent-encode a URL component or convert text to Base64, then decode it to check the original.
URL mode encodes components. A whole URL will have characters such as : and / encoded too.
URL & Base64 encoderEncode and decode Unicode text safely in your browser.
No uploadChoose the conversion
Match the mode to the value’s destination
Encode a query value
Choose URL encode and enter just the query value. URL decode restores percent-encoded characters but does not turn + into a space.
Represent text as Base64
Base64 encode uses UTF-8 bytes for Unicode text, including Korean. Decode the result to compare it with the original.
Check before copying
Changing the mode or input updates the result. If decoding fails, check whether the input matches the selected format.
