Which Is the Best Binary Language Translator?

I’m looking for a simple binary translator that can convert text into binary and binary back into readable text. I found this free tool Binary Language Translator

Has anyone tried it? What features do you think make a binary translator worth using? For me, it should be easy to use, work on mobile, and give accurate results without extra steps.

I’m also curious whether anyone uses binary translators for learning how computers store and read text, rather than just for fun.
