Frequently Asked Questions About URL Encoder / Decoder
What is URL encoding (percent-encoding)?
URL encoding replaces unsafe characters with a % followed by their hex code (e.g., space becomes %20). This ensures special characters like &, =, and # don't break URL structure.
When should I URL encode text?
Encode text when building query strings, passing user input in URLs, working with API parameters, or embedding special characters in links. Browsers handle some encoding automatically, but APIs often require explicit encoding.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL but preserves characters like /, ?, and #. encodeURIComponent encodes everything except letters, digits, and - _ . ~, making it safer for individual parameter values.
