What is the difference between a part and a whole address?

Choose "one part" for a single value, like a search word. It also changes / ? & = # and : so they cannot break the address. Choose "a whole address" to keep those characters as they are.

Why does my text have %20 in it?

A % followed by two hex digits stands for one byte. %20 is a space, and %C3%A9 is the letter é. Decode the text to read it.

Is + a space or a plus?

In a query string or form, + often means a space. Everywhere else it is a plus sign. Tick "Read + as a space" when you decode form data.

Why does decoding fail?

A % must be followed by two hex digits, like %20. A lone % or a cut-off code such as %E0%A4 cannot be read. Write a real % sign as %25.

Is my data sent anywhere?

No. Everything happens in this tab, and the page's security policy blocks it from sending data anywhere.
