URL Decode/Encode

Good!

I LOVE THIS i have came back here after a month of using it and it's awesome also i believe it can be improved by adding 2 buttons a button that decodes the result then copy it to the clipboard could be named "paste and copy result" and make it 2 buttons for both ways

Very useful when you need to archive a webpage/site via the internet archive, as the internet archive treats the encoded and non-encoded URL differently, causing the wayback machine to save a NONEXISTENT page.
