🔗 URL Encoder & Decoder — Free Online Tool

Encode and decode URLs instantly with our free online URL Encoder/Decoder tool. Convert special characters to URL-safe format or reverse encoded strings — all processing happens in your browser.

🚀 What Is URL Encoding?

URL encoding (also called percent-encoding) converts special characters into a format that can be transmitted over the internet. It replaces characters like spaces, ampersands, and question marks with a "%" followed by two hexadecimal digits.

For example:

  • Space becomes %20
  • & becomes %26
  • = becomes %3D

💡 When to Use URL Encoder

1. API Requests

When building APIs, query parameters often need to be encoded:

2. URL Parameters

Passing special characters in URLs:

https://example.com?name=John%20Doe&city=New%20York

3. Form Submission

HTML forms encode data automatically, but manual encoding helps with debugging.

Encode long URLs with special characters for reliable bookmarking.
