That one website that decodes Base64 and other scrambled-looking text

Why it's the pick

CyberChef, built by the UK's GCHQ, lets you chain hundreds of operations such as Base64, hex and URL decoding, decompression, hashing and encryption, and its Magic option tries to guess how unknown data was encoded. Everything runs in your browser, so your data isn't uploaded, but the dense interface takes a few minutes to learn.
