工具介绍
URL 编码把中文、空格和 `&`、`#`、`?` 等字符转换成百分号形式，避免在地址栏和请求里被截断或误读；解码则是反向还原。 URL encoding turns Chinese, spaces and characters like `&`, `#` and `?` into percent escapes so links and requests are not truncated; decoding restores the readable form.
范围有两种：参数值会转义 `/`、`?` 等分隔符，适合拼进查询串；完整网址会保留这些分隔符，适合整条链接。两种都支持中文与 emoji。 Two scopes: parameter values escape separators like `/` and `?`, which suits query strings; full URLs keep them, which suits whole links. Both handle Chinese and emoji.

常见问题
为什么空格变成了 %20？Why did spaces become %20?
空格在 URL 中不合法，编码后以 `%20` 表示。解码时会还原为普通空格。Spaces are not valid in a URL, so they become `%20`; decoding restores a normal space.
参数值和完整网址有什么区别？What is the difference between the two scopes?
参数值会把 `/`、`?`、`&` 也转义，适合作为某个参数的内容；完整网址会保留它们，适合整条链接。Parameter values also escape `/`, `?` and `&`, which suits a single value; full URLs keep them, which suits a whole link.
解码报错怎么办？What if decoding fails?
通常是输入里存在不完整的 `%` 转义，例如只有一个 `%`。补全或换用原始编码串即可。Usually the input has an incomplete `%` escape, such as a lone `%`. Fix it or use the original encoded string.
会记录我粘贴的内容吗？Is my input recorded?
不会。转换在浏览器本地完成，没有网络请求，也不写入本地存储。No. Conversion runs locally with no request and nothing written to storage.
