GUIDE & CONTEXT

About this tool

A full URI and a query parameter need different escaping rules. URI mode preserves structural separators such as : / ? and &, while component mode escapes characters that could change URL structure. Decoding malformed percent sequences reports an error rather than guessing the intended text.

How to use it

  1. Select component mode for a single parameter value or URI mode for a complete address.
  2. Choose encode or decode and paste the input.
  3. Convert and copy the result; encode each parameter independently when constructing a query string.
Example

In component mode, a&b=c becomes a%26b%3Dc, so the ampersand remains part of the value.
