(03) — FAQ
Short answers.
- encodeURI or encodeURIComponent?
- This tool uses encodeURIComponent. It also encodes :, /, ?, #, & — right for a parameter value, not a full URL.
- Do accents work?
- Yes. “é” becomes %C3%A9 (UTF-8). A malformed % sequence errors on decode.
- Is anything sent to a server?
- No. It stays in the tab.
