❓ FAQ

Is this tool free?

Completely free, no registration, no download. Everything runs locally: URL Encoder/Decoder and other values are processed on your device, never sent to a server.

Does data pass through a server?

No. This is a pure frontend app β€” all processing happens locally in your browser.

What's the difference between encodeURIComponent and encodeURI?

encodeURIComponent encodes all special characters including / ? & = #, ideal for URL parameter values. encodeURI preserves URL structure characters, suitable for full URLs. For query parameter values, always use encodeURIComponent.

Does it work on mobile?

Yes. Responsive design works on phones, tablets, and desktops.

Do I need to install software?

No. Just open the webpage in your browser.
