Make any text URL-safe
Spaces, ampersands and non-English characters must be percent-encoded before they go into a URL. Decoding does the reverse, turning %E2%9C%93 back into ✓.
Encode a single parameter value, or a whole URL while keeping its slashes and question marks intact.

Frequently asked questions
What's the difference between the two encode modes?
Encoding reserved characters is for parameter values; turning it off encodes a full URL but keeps : / ? & = as they are.
Why do I see + instead of %20?
HTML forms encode spaces as +. The decoder treats + as a space for you.
Is my data uploaded anywhere?
