How many bits are in a pixel? || Bits in a Pixel || 1-bit per pixel to 32-bit per pixel 

The bits in a pixel depend on the color depth of the image. Some common examples are as follows:

1. **1-bit per pixel**: Black and white images; that is, 2 colors.

2. **8-bit per pixel**: Grayscale images; 256 shades of gray.

3. **24-bit per pixel**: True color images, 16.7 million colors, normally constructed from 8 bits for each of the three color channels: Red, Green, and Blue.

4. **32-bit per pixel**: True color images with an additional 8 bits for an alpha channel. This carries the transparency information. Still 16.7 million colors, but truly translucent.

Thus, it can be deduced that, according to the image color depth, a pixel could be encoded in 1, 8, 24, 32, or more bits.
