8 bit picture converter11/9/2023 ![]() ![]() If you select the "User-defined Weights" option, then you can also create your own custom conversion formula by manually entering the weights that determine how much light is extracted from each color channel. The second method is called the "ITU-R BT.709 Formula," (also known as HDTV formula), which applies different weights to the color channels according to the formula "0.21×Red + 0.72×Green + 0.07×Blue", and the third method, known as the "ITU-R BT.601 Formula," (also known as PAL/NTSC formula) utilizes the formula "0.30×Red + 0.59×Green + 0.11×Blue". Among the most popular conversion formulas are the "Average Color Values" formula, which takes equal amounts of red, green, and blue channels and calculates their average value as "(Red+Green+Blue)/3" for the amount of light left in the image. This tool provides the three most popular grayscale conversion formulas as well as gives you the freedom to create a custom formula. There are also multiple methods for removing the color information from an image. 8-bit images allow up to 256 tones, whereas 1-bit images can have only two. The 8-bit image can hold 256 shades of grey whereas the image on the right can only hold either black or white. ![]() As the information about the amount of color is lost, we obtain a grayscale or a black-and-white image. A few areas of the 1-bit image might appear grey, but once enlarged to pixel peep, the difference becomes apparent as seen below. To create a grayscale image, the tool removes information about how much color is in each of these channels and leaves only information about the amount of light in these channels. Pixel It allows you to take an image and convert into pixel art. Use the 'local file' if you need to convert a file from your computer, in order to specify a file on the Internet, select 'Online file' and in the appeared field paste the link to the file. These three colors are stored in three separate color channels, called the red color channel, the green color channel, and the blue color channel. To convert images, follow these steps: Use the 'Local file' or 'Online file' buttons to specify how to upload the image to the server. You could try exporting as a GIF instead, which is a format that can never be interpreted as having more than 8 bits per pixel. By combining various amounts of these three colors together, we get images of all possible colors. NB: An 8-bit image codes 0 for black and 255 for white. As you may know, all colors that you see in images are actually made out of just three primary colors – red, green, and blue. Tool to convert an image into a binary of 0 and 1 (byte array format). This tool converts color images into grayscale images. ![]()
