How to use the url encoder and decoder

  1. Enter the values or text requested by the tool.
  2. Choose the available options and run the tool.
  3. Review the result.

Worked example

“hello world” encodes as “hello%20world”. Decoding reverses percent-encoded component text.

Understanding the result

This tool uses URL-component encoding, which also encodes characters such as slashes. It is intended for individual parameter values, not blindly encoding a complete URL.

Frequently asked questions

Should I encode an entire website URL here?

Usually no. Encode individual URL components, such as a query parameter value. Whole-URL encoding has different rules.

Is this URL encoder free to use?

Yes. This version of AllgoTool is free to use and does not require an account. The tool’s limits are explained above.

Supported inputs and limitations
