ABOUT URL DECODE

This page provides a specialized tool for decoding URL encoded text. URL encoding (also known as percent-encoding) is a method to encode special characters in URLs using a percent sign followed by two hexadecimal digits. This encoding is necessary because URLs can only contain a specific set of characters.

The URL Decode tool helps you convert percent-encoded characters back to their original form. For example, %20 becomes a space, %2F becomes a forward slash, and %3F becomes a question mark. This is particularly useful when working with URLs, query parameters, or any text that contains URL encoded characters.

As part of StringFlux, this tool can be chained with other operations for more complex transformations. For instance, you can decode a URL and then format it for better readability, or encode it back to URL format. If you need to encode text for URLs, check out our URL Encode Tool.

FAQ

When should I use this URL decoder tool?

Use URL decoding when handling data that has been percent-encoded for transport in URLs or HTTP requests. Typical scenarios include:

  • • Parsing query strings (?name=John%20Doe)
  • • Debugging REST API requests or server logs
  • • Handling application/x-www-form-urlencoded form submissions
  • • Decoding values from cookies, redirects, or OAuth flows

What encoding standard is used?

This tool follows the percent-encoding rules from RFC 3986 and assumes UTF-8 character encoding:

Can I decode multiple lines at once?

Yes. You can paste multiple lines or full blocks of encoded text. Each line is decoded independently, which is useful for log analysis, parameter dumps, or bulk transformations.

Is my data safe when decoding URLs here?

Yes. All decoding happens locally in your browser. Nothing is sent to a server, logged, or stored. Your input never leaves your device.

Can I see examples of URL decoding?

Yes. Here is one example:

URL encoded string:

http%3A%2F%2Fstringflux.io%2F%3Fname%3DJohn%26city%3DFremont

When you decode it with this tool, you’ll get:

http://stringflux.io/?name=John&city=Fremont
