什么是 URL 编码


当 URL 中出现空格、中文或 & 等特殊字符时，需要转义为 %XX 形式才能安全传输。本工具支持参数级与整条 URL 级两种编码模式，双向转换。


What is URL encoding


Spaces, non-ASCII text and reserved characters must be escaped as %XX sequences to travel safely in URLs. This tool offers component-level and full-URI-level modes in both directions.

FAQ
 
 
  encodeURIComponent vs encodeURI?   
The component mode also escapes reserved characters like : / ? & = — use it for single parameter values. The URI mode keeps URL structure intact — use it for a whole URL.
 
  Should spaces be %20 or +?   
Standard percent-encoding uses %20; + is a form-encoding convention. Modern APIs generally accept %20.
