Frequently asked questions

Does this only support ASCII characters?

It supports any Unicode character, not just the original 128-character ASCII set — each character is converted using its full code point.

What format should hex or binary input be in?

Space-separated values, e.g. "48 65 6c 6c 6f" for hex or "01001000 01100101" for binary.

Is my text uploaded anywhere?

No. All conversion happens entirely in your browser.
