FAQ

常见问题解答

What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes standard URLs while preserving protocol and path characters like :// and /. encodeURIComponent encodes every special character, making it ideal for query parameter values.
Does this tool support international UTF-8 characters?
Yes. It converts UTF-8 multi-byte characters (such as accents, Cyrillic, Chinese, and Arabic) into standard percent-encoded octets.
Can I decode malformed percent sequences?
If a string contains invalid sequences (e.g. an incomplete % sign), the tool alerts you with a helpful syntax error instead of failing silently.
Is any URL or token data saved?
No. All conversions happen entirely inside your browser memory using native JavaScript APIs. Zero data is logged or sent externally.
