FAQ
Can I enter a full URL?
Yes. Because it is processed as a URL component, delimiters such as /, ?, &, and = are encoded too.
Can I use Japanese text and emoji?
Yes. Japanese text, emoji, and other Unicode characters are supported.
Is a plus sign decoded as a space?
No. This tool preserves + as a plus sign. Use %20 when decoding a space.
What happens with invalid percent encoding?
If a % is not followed by valid hexadecimal digits, no result is generated and an error is shown.
Is my input sent to a server?
No. Encoding and decoding take place entirely in your browser.
