Frequently Asked Questions

What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL but preserves characters like colons and slashes. encodeURIComponent encodes everything, making it ideal for query parameter values.
When should I URL encode my strings?
You should URL encode strings whenever you pass special characters in query parameters, form data, or API requests to avoid breaking the URL structure.
Can I decode a URL that has been encoded multiple times?
Yes. Simply run the decoder multiple times until the output matches the input, which means all encoding layers have been removed.
