How binary encodes text
Computers store text as numbers. In ASCII, every letter, digit and symbol gets a code — uppercase A is 65 — and that code is written in binary, where each digit is a bit and 8 bits make 1 byte. So A becomes 01000001. Plain ASCII covers 128 characters; for everything else (é, €, emoji) modern systems use UTF-8, which spends two, three or four bytes on a single character. This translator writes one space-separated 8-bit group per byte and reverses the process when decoding, entirely in your browser.
Questions
Is anything uploaded?
No. The translation runs entirely in your browser — nothing you type or paste is uploaded or stored anywhere.
What binary format does it read and write?
Output is space-separated 8-bit bytes; characters above code 255 are encoded as multi-byte UTF-8. The decoder accepts groups separated by spaces, newlines or commas, and also a single unspaced string whose length is a multiple of 8. Invalid groups are shown as �.
Is it free?
Yes. Simple Tools is designed as a free, fast utility suite — no sign-up, no limits.
