Why URL-encode your text?

Characters such as spaces, ampersands and accented letters can break a URL or be misinterpreted as separators. Paste your text above and get a percent-encoded version that is safe to place inside a URL component or query value.

How it works

The converter applies encodeURIComponent to your text right in the browser, percent-encoding every character that is not safe in a URL component. This is exactly what you want for query parameter values and other URL fragments. Since the encoding runs client-side, your data never leaves your device.

Frequently asked questions

Is my text uploaded when I encode it?
No. The encoding is performed entirely in your browser, so your text is never sent over the network and stays on your device.
Which encoding function does it use?
It uses encodeURIComponent, which percent-encodes characters so the result is safe to drop into a URL component or query value.
When should I use this instead of full-URL encoding?
Use it whenever you are encoding a single piece of a URL, such as a query parameter value, where characters like & and = must be escaped.
