URL Encoder / Decoder
Percent-encode or decode URLs and text. Everything runs on your device.
Frequently asked questions
Component vs full URI — which should I use?
Use component mode for a single value (like a query parameter); it encodes / ? & =. Use full URI mode when the whole URL must stay a valid URL.
What characters get encoded?
Spaces become %20, non-ASCII characters become multi-byte sequences like %E4%B8%AD, and reserved characters are escaped so they travel safely in URLs.
Is my input sent anywhere?
No. Encoding runs entirely in your browser.
