Binary Translator
Convert text to binary and binary back to text, both directions at once. Full UTF-8, so accents and emoji convert back exactly as they went in.
Type in either box — the other one updates as you go.

About Binary Translator
Confileo's Binary Translator tool converts text to binary and binary back to text, in both directions at once. Everything runs in your browser, free and without signup, and your files are deleted automatically after processing.
Converting text to binary and back is mostly a learning exercise, and it is one that gets taught badly. Seeing HELLO become 01001000 01000101 01001100 01001100 01001111 is the moment the idea lands that text is numbers and numbers are bits — so this page shows both sides at once, in two boxes, either of which you can type into. Change a bit and watch the letter change; change the letter and watch the bits.
Each group of eight bits is one byte, and each byte is one character's code. Capital A is 65, which is 01000001. Lowercase a is 97, or 01100001 — exactly 32 more, which is why the difference between upper and lower case is a single bit in position six. A space is 32, or 00100000. Those relationships are visible in the output once you know to look for them, which is the point of putting the two panes side by side.
This translator encodes UTF-8 bytes rather than UTF-16 code units. For plain English the two are identical and produce the familiar eight-bit groups. The difference shows on anything else: é is two bytes in UTF-8 and an emoji is four, so both round-trip correctly here, where a converter working on code units would emit sixteen-bit groups and corrupt them. If you paste text with an accent or an emoji and convert it back, you get exactly what you started with.
Decoding is deliberately tolerant of how binary actually arrives. Everything that is not a 0 or a 1 is discarded before decoding, so binary pasted with commas, line breaks, no separators at all, or the stray characters that come with copying out of a forum post all decode the same way. Bits are then read in groups of eight; an incomplete trailing group is ignored rather than throwing an error, so the output stays sensible while you are still typing.
It is worth being clear about what this is not: binary is an encoding, not encryption. Anyone who recognises it can read it in seconds, and there is no key involved. If the goal is that a message should not be read by whoever finds it, this is the wrong tool — the site's steganography and invisible-text tools hide that a message exists at all, which is a different and more useful property than making it look unfamiliar.
The conversion runs entirely in your browser. Nothing is uploaded.

Binary Translator — Frequently asked questions
How do I convert binary to text?
Paste the binary into the right-hand box and the text appears on the left. Separators do not matter — spaces, commas, line breaks or none at all all work, because everything that is not a 0 or 1 is discarded before decoding.
What is 01001000 in text?
The letter H. Each group of eight bits is one byte holding one character code: H is 72, which is 01001000. Capital A is 65 and lowercase a is 97, exactly 32 apart, which is why case is a single bit of difference.
Does it work with emoji and accented letters?
Yes. This translator encodes UTF-8 bytes, so an accented letter becomes two bytes and an emoji four, and both convert back exactly. Converters that work on UTF-16 code units emit sixteen-bit groups and corrupt them.
Is binary a form of encryption?
No. Binary is an encoding, not encryption — there is no key, and anyone who recognises it can read it in seconds. If the point is that a message should not be read by whoever finds it, the invisible-text and steganography tools on this site hide that a message exists at all, which is a stronger property.
Is this tool really free?
Yes. Every Confileo tool is free to use with no daily caps, no watermark on your output and no credit card required.
Do I need to create an account?
No. You can use the tool straight away without signing up or logging in.
Are my files safe and private?
Yes. Your files are processed for the task you requested and then deleted automatically — they are never shared or kept.
Does it work on my phone?
Yes. The tool runs in any modern browser, so it works the same on desktop, tablet and mobile with nothing to install.
