What is URL Encoding?
URL Encoding (also known as Percent-encoding) is a mechanism for safely transmitting data through web browsers. Because URLs can only be sent over the Internet using the ASCII character-set, spaces and special characters (like &, =, ?) must be converted into a valid format. For instance, a space becomes %20. Our Free URL Encoder and Decoder performs this conversion instantly.
How to Use This Free Tool
- To Encode: Paste your normal text or messy URL parameters into the input box and click "Encode URL". All unsafe characters will be converted.
- To Decode: Paste a string filled with percent signs (like
%20or%3D) and click "Decode URL" to read the actual text. - Copy Results: Use the "Copy Result" button to save your formatted URL to your clipboard.
Is My Data Kept Private?
Yes, 100%. We understand that URLs often contain sensitive parameters, API keys, or personal tokens. That's why The Encoded Box processes everything locally using JavaScript within your browser. Your URLs are never sent to a backend server or saved in any database.
