Quick answers for URL Encode / Decode

What is URL encoding?
URL encoding (percent-encoding) converts characters that have special meaning in URLs - like spaces, &, ?, and = - into a safe form so they can be passed in a link or query string without breaking the URL.
When do I need to URL-encode a string?
Any time you embed user input, paths, or query parameters into a URL - building deep links, constructing API requests, or debugging a broken redirect. Encode values individually, not the whole URL.
What's the difference between encodeURI and encodeURIComponent?
encodeURIComponent encodes every reserved character, which is what you want for query values and is what this tool uses. encodeURI leaves URL structural characters (/ ? : etc.) alone, which is rarely what you want when encoding user-supplied data.
Does URL encoding change my original data?
No. URL encoding is fully reversible - decoding gives you back the exact original string, byte for byte. The tool provides both directions.
Is the URL Encode tool safe for private URLs?
Yes. All encoding happens in your browser. URLs with tokens, session IDs, or other private parameters are not logged or sent anywhere.
