URL Encode / Decode

What is URL Encoder / Decoder?

URL encoding (percent-encoding) replaces special characters with %XX sequences so they can be safely used in URLs. This tool encodes plain text for use in query parameters and decodes percent-encoded strings back to readable text, with full Unicode support.

Common Use Cases

• Building query strings with special characters or spaces
• Debugging encoded URLs from logs or redirect chains
• Encoding form data for application/x-www-form-urlencoded requests
• Decoding OAuth callback URLs with encoded parameters

How to Use

1. Choose Encode or Decode mode
2. Paste your text or encoded URL into the input
3. Copy the result or use Swap to reverse the operation
