URL Encode / Decode
Encode or decode URL strings instantly by pasting text into the input field.
This tool supports percent-encoding commonly used in URLs, making it easy to convert special characters into a safe format
or restore encoded strings back to readable text.
It is useful for building query parameters, checking API request URLs, and debugging encoded values found in logs or configuration files.
With a single click, you can switch between encoding and decoding
and view the result immediately.
All processing is performed locally in your browser.
No input text or results are sent to any server, ensuring fast performance and privacy-safe usage.
URL Encoder and Decoder
URLs often need special characters, spaces, non-English text, and symbols to be percent-encoded. This URL encoder and decoder helps you convert readable text into URL-safe strings and decode encoded values such as %20, %2F, or UTF-8 sequences.
Common use cases
- Debug query strings: Decode parameters from tracking links, API requests, or redirects.
- Prepare safe URLs: Encode search terms, callback URLs, filenames, and form values.
- Inspect copied links: Understand what a long encoded URL actually contains.
Encoding note
Different contexts encode spaces and reserved characters differently. A value that is safe in a query parameter may not be safe in a path segment, so check the exact place where the value will be used.
