How It Works

  1. 1

    Choose encode or decode mode

  2. 2

    Paste a URL, query string, or URI component

  3. 3

    The tool converts the value using standard URL encoding rules

  4. 4

    Copy the output for APIs, links, redirects, or debugging

Use Cases

  • Encode query parameters before adding them to a URL

  • Decode copied URLs to inspect hidden characters and parameters

  • Debug API requests, redirect URLs, and webhook payloads

  • Prepare safe links that include spaces or special characters

  • Clean up encoded strings during development and QA

Frequently Asked Questions

What is URL encoding?

URL encoding converts spaces and special characters into safe percent-encoded sequences so they can be included in URLs and query strings.

Does this encode the whole URL or only parts of it?

The tool uses URI component encoding, which is most useful for query parameter values and individual URL parts. Full URLs can still be decoded for inspection.

Is my URL sent anywhere?

No. Encoding and decoding happen in your browser.

Why did decoding fail?

Decoding fails when the input contains malformed percent-encoded sequences, such as a percent sign that is not followed by valid hexadecimal characters.
