Frequently Asked Questions
What is URL decoding?
URL decoding converts percent-encoded characters such as %20 back into their original readable characters.
Is this URL Decoder free?
Yes. The URL Decoder is free to use and does not require registration.
Does this tool upload my URL to a server?
No. The decoding operation is performed directly in your browser using JavaScript.
Why does + become a space?
In URL query-string and form-encoded data, a plus sign is commonly used to represent a space. You can disable this behavior with the decoder option.
What happens if the URL contains invalid encoding?
The tool detects malformed percent-encoded sequences and displays an error instead of producing an unreliable result.
Does URL decoding execute JavaScript?
No. The tool only processes text and does not execute decoded JavaScript or other code.
