Frequently Asked Questions
How does URL encoding work?
URL encoding (percent-encoding) converts characters into a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a \"%\" followed by two hexadecimal digits.
Can I decode a URL here?
Yes, simply paste the encoded text and click 'Decode' to revert it to human-readable text.
What happens if I decode an invalid URL?
The tool will display an 'Invalid encoded URL' error if the input contains malformed percent-encoding sequences.
