URL Encoder

Percent-encode text for URLs and query values in your browser.

Tool workspace

Encoding runs in your browser with encodeURIComponent (component rules). Nothing you paste is sent to our servers.

How it works

Paste or type text into the input. The tool percent-encodes it with JavaScript’s encodeURIComponent — the same component encoding used for query parameter values (spaces become %20, and reserved delimiters such as &, =, ?, #, /, and : are escaped).

This is not encodeURI, which leaves URL structure characters unescaped. Empty input produces an empty result—no error.

Results update as you type (light debounce) or when you press Convert. Encoding runs entirely in your browser.

Domain tests mirror encodeURIComponent via PHP rawurlencode with the five characters encodeURIComponent leaves unescaped restored (! ' ( ) *).

Examples

  • hello world → hello%20world
  • a&b=c → a%26b%3Dc
  • café → caf%C3%A9
  • path/to?q=1 → path%2Fto%3Fq%3D1

Privacy

FAQ

Is my text uploaded to a server?

No. URL encoding runs entirely in your browser. Pasted content is not sent to Nova Engine.

Do I need an account?

No. All published tools work for guests without login.

encodeURIComponent or encodeURI?

This tool uses encodeURIComponent (component / query-value rules). It does not use encodeURI, which leaves delimiters like ?, #, and / unescaped.
