Frequently Asked Questions
What is URL encoding?
URL encoding (percent encoding) converts special characters into %XX format so they can be safely transmitted in a URL, replacing spaces with %20, etc.
Will my data be uploaded to a server?
No. All encoding and decoding is done locally in your browser. Your text never leaves your device, fully protecting your privacy.
What is 'encode all characters' mode?
Full encode mode encodes every character including letters and numbers, not just special characters. Useful for obfuscation or strict encoding requirements.
Does it support Unicode characters?
Yes. The tool processes text with UTF-8 encoding and correctly encodes Chinese, Japanese, and other multilingual characters.
What happens if I decode an invalid string?
If the input contains invalid percent-encoded sequences, an error message is shown indicating the specific problem.
Is this tool free to use?
Completely free. This is a pure frontend online tool - no registration required, no payment needed, just open and use.
