How URL encoding works
The tool applies percent-encoding to a URL component. Reserved and unsafe characters are represented as UTF-8 %XX sequences.
Practical example
Encoding is useful for query parameter values. The decoder also interprets + as a space for compatibility with HTML form data.
Local processing
URLs and parameters are processed only in your current browser tab.
Frequently asked questions
Should I encode an entire URL?
Usually you encode individual parameter values. Encoding a full URL also escapes structural characters such as : / ? and &.
Why does a space become %20?
A space is not a safe URL character and is represented by the UTF-8 sequence %20.
