URL Encoder and Decoder可以处理什么？
URL Encoder and Decoder 用于在浏览器中编码或解码内容，并清楚显示处理结果和限制。 已核对的功能： Component encoding, Full URL encoding, Malformed-sequence errors, Query-string parsing.
Component mode and full-URL mode are not interchangeable
Use component mode for a path segment, key, or parameter value. Use full-URL mode only when a complete URL already contains structural separators that must remain readable.
如何使用？
- Choose whether the input is one component, a complete URL, or a query string.
- Paste the value into Input; conversion runs immediately when the text or operation changes.
- Inspect the encoded text or parsed query JSON, then copy or download it.
实际输入输出示例
Encode one query-parameter value
输入
hello world & tea输出
hello%20world%20%26%20teaEncode component escapes spaces and the ampersand so the value cannot be mistaken for a query separator.
常见错误与修复方法
| 现象 | 可能原因 | 修复方法 |
|---|---|---|
| Decode component reports a malformed URI sequence. | A percent sign is not followed by two hexadecimal digits or the bytes are not valid UTF-8. | Correct the incomplete escape instead of repeatedly decoding the value. |
| A full URL loses its separators after encoding. | Encode component was used on the whole URL. | Use Encode full URL to preserve :, /, ?, #, and other structural delimiters. |
Important behavior of URL Encoder
该工具的实际边界： Use component mode for one parameter value; full-URL mode intentionally preserves URL separators.

关于URL Encoder的常见问题
Does the URL Encoder upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the URL Encoder accept?
It accepts plain text, an encoded component, a full URL, or a query string. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the URL Encoder produce?
It produces encoded text, decoded text, or JSON query parameters. Copy and download controls appear when the output format supports them.
What limitation should I know?
Use component mode for one parameter value; full-URL mode intentionally preserves URL separators.
