URL Encoder & Decoder FAQ
Use it when your URLs or query parameters contain spaces, special characters, or symbols that break requests.
It converts unsafe characters into percent-encoded form (for example, space becomes %20) so URLs remain valid.
encodeURI is used for full URLs and keeps reserved characters. encodeURIComponent is used for query values and encodes reserved characters too.
%20 is the encoded form of a space character. It is normal in valid URLs.
Decoding is safe for debugging and readability. Always validate decoded values before using them in code to avoid injection issues.
If the converter runs in your browser, input stays local and is not uploaded or stored on servers.
