Convert Any Value, and See How the Conversion Works
Every conversion on this site rests on one idea: a value keeps its meaning while its form changes. For number bases, number system conversion states that idea once, and each converter here applies it. The result comes first, then the working behind it.
Type in the left box and the binary appears on the right as you go. Turn on Show steps to see each character, its code, and the sum that produces it.
Where the method is explained
- every conversion in this family — the binary, octal, decimal, hex, text and ASCII pairs in one grid.
- turn words into binary code — one character at a time, with the eight bits printed for each.
- the two universal conversion methods — repeated division and positional expansion, worked end to end.
- how binary represents letters and numbers — what binary is, before any converter touches it.

the full tool index lists every page on the site, grouped the same way. It also holds the calculators, generators and downloads in a group of their own: those make a new value rather than change the form of one you already have.
Every tool runs in your browser. Nothing you type leaves the page, the result is instant, and the method sits beside it so you can check the answer by hand.
