URL Encoder

FAQ

Is this the same as encodeURI?+

No. This tool uses encodeURIComponent, which escapes reserved characters like &, =, ?, and #. That is the usual choice for query values.

How are spaces encoded?+

Spaces become %20. A plus sign (+) is not used — that form belongs to application/x-www-form-urlencoded, not component encoding.

Is my data uploaded?+

No. Encoding runs entirely in your browser. Your input never leaves the device.

Should I encode the full URL or only a query value?+

Encode individual query values or path segments with this tool. Encoding an entire URL with encodeURIComponent will also escape : and / — use encodeURI when you need to preserve those delimiters.

How does Unicode appear in encoded output?+

Non-ASCII characters become UTF-8 percent sequences such as %C3%A9 for é. That matches what most JavaScript encodeURIComponent implementations produce.
