What is the difference between an 8-bit image and a 16-bit image?
The main difference between an 8 bit image and a 16 bit image is the amount of tones available for a given color. An 8 bit image is made up of fewer tones than a 16 bit image. The amount of tones available are calculated by 2 to the exponent of the bit.
What size is an 8-bit image?
In an 8-bit image each pixel occupies exactly one byte. This means each pixel has 256 (28) possible numerical values, from 0 to 255. Therefore, the color palette for an 8-bit image normally contains 256 entries, defining color 0 through color 255.
How many bytes is an image?
Compatible File Types
| Image Type | Bytes per pixel | Compatible File Types |
|---|---|---|
| 1-bit Line art | 1/8 byte per pixel | TIF, PNG, GIF |
| 8-bit Indexed Color | Up to 1 byte per pixel if 256 colors | TIF, PNG, GIF |
| 8-bit Grayscale | 1 byte per pixel | Lossy: JPG Lossless: TIF, PNG |
| 16-bit Grayscale | 2 bytes per pixel | TIF, PNG |
What is the difference between 8bit and 16-bit?
So, an 8-bit image doesn’t have 8 colors. Instead, it can hold 256 tonal values in three different channels (red, green, and blue). That equals 16.7 million colors. A 16-bit image has 65,536 tonal values in the same three channels.
What is difference between 8-bit and 16-bit?
What is the difference between 8-bit and 16-bit?
What is a 16-bit image?
An image with 16 bits per channel will have up to 2^16 shades per channel, or 65536. If you have an RGB image where each of Red, Green, and Blue has 16 bits, you must multiply 65536 × 65536 × 65536 to see that the image can hold up to 281 trillion colors in total.
How big is a JPEG image in bytes?

What is 8bit image?
8-bit color graphics are a method of storing image information in a computer’s memory or in an image file, so that each pixel is represented by 8 bits (1 byte). The maximum number of colors that can be displayed at any one time is 256 or 28.
