How it works

Each %XX sequence is decoded back to its byte value (UTF-8 aware).

Examples

Input	Output
hello%20world	hello world
a%26b%3Dc	a&b=c
%E5%92%96%E5%95%A1	咖啡

Frequently Asked Questions

What does + mean here?

In query strings, + often represents a space — this tool converts it automatically.

Why do I get an error?

A lone % not followed by two hex digits is invalid percent-encoding.

Is decoding lossless?

Yes — valid percent-encoding always decodes to the original bytes.
