This browser-based utility creates grayscale versions of logos from colorful PNG logos. It converts the full spectrum of colors in the input logo into variations of gray tones using various conversion methods. The standard and simplest method for converting colors to grayscale is the method of averaging the RGB components. It simply takes the average value of the three RGB (Red, Green, Blue) components for each pixel using the formula "(R + G + B)/3". A more modern method is based on the HDTV standard used in contemporary televisions. It takes into account the peculiarities of human color perception and gives more weight to the green color, using the formula "0.21R + 0.72G + 0.07B". The classic PAL/NTSC method is based on the older television standards PAL and NTSC. It also considers the peculiarities of human color perception but does so slightly differently, using the formula "0.30R + 0.59G + 0.11B". You can choose from these standard grayscale conversion methods or create your own formulas. To do this, activate the custom channel weights mode and specify the multiplier for each color channel. You can also control the number of gray shades in your output logo, ranging from the full palette of 256 colors to a limited spectrum of gray tones. Png-abulous!

In this example, we convert the iconic Rolex logo into a subdued grayscale version. We use the standard conversion method by averaging the RGB components of each pixel. The result is a classic Rolex design in monochrome. (Source: Wikipedia.)
In this example, we create a grayscale version of the British Petroleum logo using the modern HDTV method. This conversion method best captures the green shades of the pixels, as it takes into account the human eye's sensitivity to the green spectrum. As a result, the green-yellow BP logo transforms into gray tones that maintain a clear transition from light to dark shades, making the brand well-recognizable in grayscale. (Source: Wikipedia.)
In this example, we convert the PetroChina logo to grayscale format, setting custom channel weights and a fixed number of colors. We use a multiplier of 0.25 for red, 0.65 for green, and 0.1 for blue. We also limit the number of gray shades to 24, resulting in the logo's smooth gradients being broken into sections of lighter to darker gray tones. (Source: Wikipedia.)
