FAQ
Why does Korean text turn into sequences like %ED%95%9C?
URLs only allow ASCII, so Korean characters are written as their UTF-8 bytes in %XX form. This tool converts both directions.
Should I encode only the query parameter value?
Yes. It uses encodeURIComponent, which suits parameter values. Note that pasting a full URL also encodes separators like ://.
