What does URL Encoder / Decoder do?
Encode or decode URL text using encodeURI or encodeURIComponent. Compare complete-address and parameter-value encoding when debugging links or building API requests.
Interpreting results and common questions
Should I use encodeURI or encodeURIComponent?
encodeURI preserves some URL separators; individual parameter values commonly need encodeURIComponent. Check whether input is already encoded to avoid double encoding.
References and result limitations
Local results depend on the input and selected options. Retain the input example, format and processing rules when citing a result, and verify the output. Keep keys and other sensitive material out of public examples.
