URL 编码 / 解码

将字符串进行 URL 百分比编码。

关于URL 编码 / 解码

URL encoding (percent-encoding) replaces reserved and non-ASCII characters with %XX sequences so URLs remain valid in browsers and servers. It is essential for query strings, redirects, and debugging encoded logs. toco.tools encodes and decodes strings locally so you can verify API parameters and human-readable values quickly. Encoding scope matters: encode full URLs versus individual query values differently. Avoid double-encoding strings that are already escaped.

使用方法

  1. Enter a URL or string
  2. Pick encode or decode
  3. Copy the output

常见问题
