What Is URL Encoder?
URL encoding (percent-encoding) converts unsafe characters into a safe format for URLs and query strings.
What is URL encoding?
Characters that are unsafe in URLs — spaces, &, ?, #, and non-ASCII characters — are replaced with a % followed by their hex code. Component encoding also encodes reserved characters like /.
When to encode
Encode query parameter values to prevent breaking URLs, and encode user input before adding it to links.
