Frequently Asked Questions

What is URL encoding?
URL encoding, also known as percent-encoding, converts special characters in a URL into a format that can be safely transmitted over the internet. Characters like spaces, ampersands, and question marks are replaced with percent-encoded values such as %20, %26, and %3F.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL but preserves characters that are valid in a URL structure, such as colons, slashes, question marks, and hash symbols. encodeURIComponent encodes everything except letters, digits, and a few special characters, making it ideal for encoding individual query parameter values.
When should I use URL encoding?
You should use URL encoding whenever you include user input or special characters in a URL, especially in query string parameters. This prevents issues with reserved characters breaking the URL structure and ensures data is transmitted correctly between client and server.
Is my data safe?
Yes! All processing happens entirely in your browser. Your data is never sent to any server. No data is collected, stored, or transmitted.
How does the URL parser work?
The URL parser uses the built-in browser URL API to break a full URL into its individual components: protocol, hostname, port, pathname, query parameters, and hash fragment. Each query parameter is displayed as a separate key-value pair for easy inspection.
