URL encoder / decoder
"Component" mode escapes everything, including / & ? — use it for a single query value. "Full URL" mode leaves URL structure characters alone.
What is URL encoder / decoder?
URLs can only safely contain a limited set of characters — percent-encoding (also called URL encoding) is how spaces, symbols, and non-ASCII characters get represented so they survive being sent as part of a web address.
How to use it
"Component" mode escapes everything including / & ? — use it for a single value going into a query string. "Full URL" mode leaves the URL's own structural characters alone.
Example
hello world -> hello%20world (component mode)
https://a.com/search?q=hello world -> https://a.com/search?q=hello%20world (full URL mode)
