Smart Grayscale Converter is a free image utility that can introduce a Color Splash effect (or Dark mood) to your RGB photographs. The tool converts an RGB image to gray-scale, while you have the Smart option to select a color to keep. This photo effect is a great way to highlight a part of your photos or illustrations.
You can use this online application to turn the entire image into monochrome or keep a color tint intact. This way you can draw extra attention to what you think is the important part of the image.
The gray scale converter supports many popular image formats such as PNG, SVG, JPEG (JPG). Works online without registration and watermark! No need to download or install it! Just a few clicks and you have a mixture of gray-scale and color image.
How it works?
Grayscale Converter uses color-space transformations to merge RGB channels into a monochrome color. At the same time, the user can select a specific color to keep in the full spectrum.
