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.
How to use & features
- Enter text at the top and click Encode or Decode to transform it.
- Review how spaces and special characters change, then copy the output for reuse.
- Long query strings are supported; very large inputs may take a moment to process.
- All conversions run locally with no network requests.

Notes & limitations
Work stays in your browser
Inputs and outputs remain local. Closing the tab or clearing cache will remove any temporary state.
Validate critical data
Results are helper outputs—double-check them before sending to production systems or sharing externally.
Large payloads depend on your device
Very large text or files can feel slow in some browsers. Use a desktop environment for heavy workloads.
