About URL 编码/解码
Encode or decode URL components. Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.
Encode the value, not blindly the entire URL
Percent-encoding is meant to keep data characters from being mistaken for URL syntax. A query value containing spaces or & needs encoding; the structural ?, = and & around it usually do not.
Double-encoding is a common bug. If % becomes %25 repeatedly, inspect whether an already encoded value was passed through the encoder again.
A realistic example
Encode “red & blue” as a query parameter value before inserting it into the URL, then decode once to confirm the original value returns.
When this tool is not the right fit
Do not repeatedly decode untrusted URLs without understanding how the application will use the result.
这个工具的作用
URL 编码将字符转换为百分比编码形式，以便在 URL 组件中安全使用；解码会反转该表示。
常见用例
- 对查询值进行编码
- 检查编码的 URL
- 准备重定向参数
- 调试网络请求
限制
- 对完整 URL 进行编码和对一个查询参数进行编码是不同的操作。

Check the input format and review the output before replacing an original file or using the result in an important workflow.
