Frequently asked questions

Why is one Cyrillic letter two bytes?

UTF-8 encodes Cyrillic with two bytes, and emoji with four. The converter shows the actual byte sequence, so ASCII text takes one byte per character.

How do I decode binary back to text?

Switch to decode mode, paste bytes (separated by spaces, commas or newlines) and choose the right format — binary must be 8 bits per byte.

What is the difference from ASCII conversion?

ASCII only covers 128 English characters. UTF-8 is a superset and encodes any Unicode text, which is what this tool uses.
