URL Decode
Runs in your browser — your data is never uploaded.
Turn a percent-encoded URL or query string back into readable text. Paste anything with %XX escapes — a tracking URL, an encoded redirect, a log entry — and OkConverter decodes it instantly, including multi-byte UTF-8 sequences. Decoding runs entirely in your browser, so the URLs you inspect stay private.

Frequently asked questions
Why do I get an invalid percent-encoding error?+
A “%” in the input must be followed by exactly two hexadecimal digits. A lone “%” or a truncated escape like “%E” is malformed — often a sign the string was cut off mid-character.
Does it convert + into spaces?+
No — it applies strict RFC 3986 decoding, where “+” is a literal plus sign. The “+ means space” rule only applies to form-encoded data; if your string uses it, replace “+” with spaces first.
Can I decode a full URL?+
Yes. Paste the whole URL — already-safe characters pass through unchanged and only the %XX escapes are decoded.
Is anything uploaded?+
No. Decoding happens locally in your browser — handy when the URL contains session tokens or personal data you don’t want to paste into a random website’s server.
