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". Black & White uses a 2 bit color space, Grayscale is 8 bit. 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. Its still and RGB image, using a 16/24/32 bit RGB color space. ![]() This tool provides the three most popular grayscale conversion formulas as well as gives you the freedom to create a custom formula. Choose to make an image black and white online and amplify the underlying emotions. The transformation is both rapid and precise, resulting in a professional-quality finish where every shade and tone is intricately represented. There are also multiple methods for removing the color information from an image. Use our online tool to quickly convert images to black and white online. As the information about the amount of color is lost, we obtain a grayscale or a black-and-white image. 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. These three colors are stored in three separate color channels, called the red color channel, the green color channel, and the blue color channel. By combining various amounts of these three colors together, we get images of all possible colors. As you may know, all colors that you see in images are actually made out of just three primary colors – red, green, and blue. The photo can be of anything like portraits, selfies, couple photos, abstracts, pets, and even landscapes. Upload a picture you want to convert into a sketch. Firstly, click the button 'Turn Photo into Sketch Now' to get started. Each dithering type scatters the pixels differently so you can create multiple two-color images.This tool converts color images into grayscale images. It is easy to convert your photo to pencil sketch. There are several types of dithering and you can switch between them in the options. ![]() With the dithering option enabled, the density of pixels conveys the details, shadows, and shapes in the image. Additionally, the program can randomly scatter the pixels and apply the dither effect. This algorithm finds and merges all pixels together into two independent groups depending on each pixel's color, resulting in large patchy areas of either color. Behind the scenes, the program uses a k-means image quantization algorithm with the "k" parameter equal to "2". For example, your two colors can be "black" and "white", or "#ff0000" and "#ffff00" (which is hex-speak for red and yellow), or "rgb(255, 192, 203)" and "rgb(0, 128, 0)" (which means pink and green in computer language). If you use your own colors, then switch on the "Manual Color Selection" option and specify any two colors in the color-one and color-two fields below. ![]() This mode calculates the most fitting color for dark areas and another color for light areas. The automatic color mode can be turned on via the "Auto Color Selection" option. Optionally, you can enter two colors yourself that will be used to redraw the PNG. It analyzes the PNG and automatically chooses the two best colors that can approximate the entire image. This browser-based utility creates a duotone PNG image from a full-color PNG image.
