FAQ
What is URL encoding?
URL encoding converts special characters into a format that can be safely transmitted in URLs. Characters are replaced with a percent sign followed by two hex digits (e.g., space becomes %20).
When do I need URL encoding?
You need URL encoding when including user input, query parameters, or special characters in URLs. It ensures that URLs are valid and data is not corrupted during transmission.
What is the difference between encodeURI and encodeURIComponent?
encodeURIComponent encodes all special characters including URL structure characters like :/?#. encodeURI preserves URL structure and only encodes characters that are not valid in URLs.
