Frequently Asked Questions
URL encoding converts special characters into a format that can be safely transmitted in URLs. Spaces become %20, for example.
URLs have strict rules about which characters are allowed. Our URL encoder/decoder converts special characters to their percent-encoded equivalents (like space to %20) and back, ensuring your URLs work correctly across all browsers, APIs, and web services without breaking.
Did You Know?
URL encoding is also called 'percent encoding' because special characters are replaced with a % followed by two hexadecimal digits. The encoding scheme was defined in 1994 as part of RFC 1738. Interestingly, the + sign for spaces only works in query strings - in the path portion, spaces must be %20!
- Encode only the query string values, not the entire URL - encoding slashes and colons breaks URLs
- Use encodeURIComponent() for query parameters and encodeURI() for full URLs in JavaScript
- Double-encoding (encoding already encoded text) is a common bug - decode first if unsure
