URL Decode
Decode URL-encoded text
Enter URL encoded text to decode back to readable text
What is URL Decoding?
URL decoding converts percent-encoded characters back to their original form. This tool decodes URL-encoded strings, converting sequences like %20 back to spaces and %3F back to question marks.
How to Use
- Paste the URL encoded text into the input field
- Click "Decode URL"
- View the decoded, human-readable text
Example
Input (URL encoded):
Hello%20World!%20How%20are%20you%3FOutput (Decoded):
Hello World! How are you?Common Encoded Characters
- %20 → Space
- %21 → !
- %23 → #
- %24 → $
- %26 → &
- %3D → =
- %3F → ?
Error Handling
If the input contains invalid URL encoding (malformed percent sequences), the tool will display a clear error message. Common issues include:
- Incomplete percent sequences (% not followed by two hex digits)
- Invalid hex characters
- Corrupted or truncated encoded data
Frequently Asked Questions
When do I need URL decoding?
Use URL decoding when you need to read URL-encoded data from query parameters, API responses, or log files. It converts the encoded format back to human-readable text.
Why am I getting a decoding error?
Decoding errors occur when the input contains invalid percent sequences. Make sure the text is properly URL encoded and hasn't been corrupted or truncated.
Can I decode an entire URL?
You can, but typically you only need to decode specific parts like query parameter values. Decoding an entire URL might break its structure.
Is my data sent to a server?
No, all decoding happens in your browser. Your data never leaves your device.
