URL Encode / Decode
Percent-encode URLs and query parameters, or decode encoded strings back to readable text. Updates as you type.
🔧
URL Encode is coming soon. In the meantime, try the JSON → CSV converter, which has flattening built in.
How it works
Live encode/decode as you type
Switch between encode and decode modes. Choose encodeURIComponent (for parameter values) or encodeURI (for full URLs). Output updates on every keystroke.
Example
Encoding a query string parameter containing special characters
Input
user@example.com & plan=pro+trial
Output
user%40example.com%20%26%20plan%3Dpro%2Btrial
Frequently asked questions
When should I use encodeURIComponent vs encodeURI?
encodeURIComponent for individual query parameter values. encodeURI for a full URL where you want to preserve the : / ? # & structure characters.
