This is a simple browser-based JPEG picture-to-grayscale converter. As soon as you paste your JPEG file in the input area, the program will create a grayscale version of this JPEG in the output area. You can use one of the known methods for conversion, or create a custom grayscale method yourself. Additionally, you can set a custom number of gray shades (from 1 to 256) to use in the output palette. Created by mad scientists from team Browserling.

This tool converts JPG photos to a grayscale version by removing all color information from the photo. There are many different ways to convert color components to grayscale and this tool supports the three most popular methods: "BT-709 (HDTV)", "BT-601 (PAL/NTSC)", and "Average Red, Green, Blue". The BT-709 grayscale method is the most common method for converting colors to grayscale. It's used in high-definition TVs and other modern digital video standards. The BT-601 grayscale method is similar to the BT-709 method, but it uses slightly different weights for red, green, and blue color channels. It's used in regular broadcast television in most countries around the world. The average component grayscale method is the simplest way to convert colors to grayscale. It simply computes the average value of the three color components (red, green, and blue) and uses this value as the grayscale value. For a more advanced JPG to grayscale conversion, you can enable the custom grayscale checkbox option and create your own conversion method by specifying coefficients for the red, green, and blue channels. In addition to these options, there is an additional option to limit the number of colors in the output JPG. This parameter allows you to create a grayscale JPG with a specific number of gray shades (for example, 30, 15, 5, or even just 2). Jpgabulous!

This example converts a JPEG photo of hills to grayscale colors, using the same grayscale algorithm that's employed in HDTV broadcasts. The ITU-R BT-709 formula gives significant priority to the green channel over other channels as the eye is most sensitive to the green color. (Source: Pexels.)
This example removes all colors from a JPG picture of snowy mountains by applying custom weights to red, green, and blue (RGB) color channels during the conversion process. It extracts RGB colors in equal parts by assigning a coefficient of 1 to each component. The formula takes the form: 1×Red + 1×Green + 1×Blue after which the value is truncated to the maximum value of 255. (Source: Pexels.)
In this example, we transform a full-color image of ripe strawberries arranged in a circular pattern on a plate into grayscale tones. The reduction is achieved by using the BT-601 color transformation standard. Furthermore, we have activated the option to limit the grayscale color palette of the JPG. We have set the color count to 10, which means that the resulting JPG only has ten distinguishable gray colors. (Source: Pexels.)
This example converts a JPG photo into grayscale tones using an exceptionally small number of colors. It redraws an entire city built on a hillside, utilizing only four shades of gray. Despite this severely restricted palette, the program still successfully captures all the details of the city streets and houses. It's an effective demonstration of how a limited color palette can still capture spatial depth and texture. (Source: Pexels.)
This example enables a custom conversion method and sets the red color intensity to one while disregarding the green and blue colors by setting their intensities to zero. Consequently, only the red color component influences the pixel color in the output JPEG. As you can see, the resulting JPEG has a full light intensity in the red section, which can be seen as bright white pixels, while the green and blue portions have no intensity and have black pixels. This conversion method illustrates how digital images are composed of color channels and how manipulating these channels can dramatically alter the appearance of the image.
