# Binary Zeros Counter

## World's Simplest Binary Tool

Free online binary zeros counter. Just load your binary values and the number of unset bits will be automatically calculated. There are no ads, popups, or nonsense, just an awesome low bit counter. Load binary values – get the number of zeros. Created for developers by developers from team Browserling.

#### Multi-line Mode

Individually find 0's in each line.

## What Is a Binary Zeros Counter?

This utility counts the number of zeros in binary numbers. By default, it operates in multi-line mode, which allows you to enter binary numbers on each line and get the result for each value. If you want to get the total number of low bits in all numbers, simply turn off the multi-line option. The input binary values can contain any number of bits and they can also have base-2 prefixes "b", "B", "0b", "0B" or base-2 suffixes "b", "B", "₂". Simple and easy!

### Zeros for Multiple Binaries

In this example, we count the number of zeros of three binary values. Since the multi-line option is enabled, the number of unset bits in each number is printed next to it in the output.

### Total Number of Zeroes

In this example, we have loaded six binaries in the input and turned off the multi-line option. As a result, the output displays the total number of low bits in all numbers. The symbols '0' that is used in binary prefixes '0b' and '0B' is not counted in the total amount.

### Large Binary Value

In this example, the binary representation of the input number contains 512 characters. Our algorithm is instantly able to tell how many zero bits there are and it turns out there are 267 zero bits in this number.
