Binary NOT
Compute bitwise NOT of a binary value locally in your browser.
Tool workspace
Bitwise NOT inverts each bit of the input (max 256 bits). Nothing you paste is uploaded.
How it works
Enter one binary value (digits 0 and 1). Whitespace is ignored.
Each bit is inverted within the input width (up to 256 bits). The result is shown as binary plus an unsigned decimal companion line.
Everything runs in your browser. Nothing you paste is uploaded.
