Is it safe to use this for private keys?

Yes. Because every conversion happens locally in your own browser, your data is never sent to a server.

Can I turn binary back into plain text?

Yes. Just paste your binary string (the 0s and 1s) and hit decode to turn it back into readable text.

Are there any limits on how much I can convert?

You can process very large strings-the only real limit is your device's available memory.
