URL Encode / Decode
IPOK dev tools provide fast network diagnostics and data conversions, including IP purity, subnet risk, DNSBL blacklist, and ASN routing lookups.
URLs can't contain raw spaces, Unicode or special symbols, so browsers turn them into %XX form (URL / percent encoding). Debugging APIs, reading logs, splitting query params or reproducing a link with non-ASCII text means constantly switching between encode and decode.
This tool runs encodeURIComponent / decodeURIComponent entirely in your browser — Unicode and emoji stay intact, and nothing is uploaded.
Local only, never uploaded. Strings like %E4%B8%AD in captured traffic are URL-encoded — common when debugging APIs, reading logs, or splitting query params.
