FAQ
Can I convert binary, decimal, and hex here?
Yes. Type a whole number and two bases from 2 to 36. 255 in base 10 becomes FF in base 16.
Is this uploaded?
No. Conversion stays in this tab.
Is this the text-to-binary tool?
No. This converts one integer. The binary tool turns letters into groups of 8 bits.
Can I use a 0x prefix or a fraction?
No. Do not type 0x or 0b, and do not type a decimal point. A digit must exist in the source base, so 2 is not a binary digit.
Can I copy the result?
Yes. Copy puts the converted integer on the clipboard. Letters are uppercase.
