URL Encoder & Decoder | Online Escaping Tool
Percent-encode or decode text—handy for query values and general escaping
Free online URL encoder/decoder: convert special characters, CJK & non-ASCII text to safe percent-encoded format via encodeURIComponent. For API params, link sharing & i18n URLs.
How to use
When to use
Debug query strings, encode parameter values, or escape text that contains spaces and Unicode for URL components.
Encode
- Click Encode to run encodeURIComponent on the entire input.
- This matches the common pattern for a single query parameter value.
Decode
- Click Decode to run decodeURIComponent first.
- If that throws, the tool tries decodeURI which is looser for some characters.
Notes
- Full URLs mix path, query, and fragment rules; this tool targets general text, not a full URL parser.
- Do not paste secrets into untrusted environments; processing stays in your browser.
