Veelgestelde vragen
What's the difference between encodeURI and encodeURIComponent?+
This tool uses encodeURIComponent — it escapes every special character. encodeURI is more conservative (leaves slashes, &, =, etc.) and is meant for whole URLs, not for query parameter values.
Why didn't a + sign get decoded to space?+
Strict percent-encoding uses %20 for space, not +. The + → space mapping is application/x-www-form-urlencoded, an older form-encoding scheme used by HTML forms.
Is it safe to put credentials in a URL after encoding?+
No. Encoded or not, URL parameters appear in server logs, browser history and referrer headers. Use POST bodies or Authorization headers for credentials.
