FAQ

How do I convert letters to binary online?

Simply type or paste your letters into the converter above. Each letter is automatically converted to its 8-bit binary representation. For example, "A" becomes "01000001". The tool processes all letters instantly and displays the binary output.

Is unicode supported?

Yes, the text is encoded as UTF-8 bytes first.

Can I remove spaces from the binary output?

Yes! Enable the "Remove spaces" option to get continuous binary output without spaces. This is useful when you need compact binary strings for programming or data storage.
