Png contrast changer tool What is a png contrast changer
This browser-based program changes the contrast of PNG images. It allows you to increase the color saturation of pixels, make them brighter and more expressive, or decrease the color saturation of pixels, make them dimmer and grayer. By default, every uploaded PNG has a 100% contrast. If you increase the contrast value to, for example, 140% or 160%, the PNG gets filled with more vivid colors. If you decrease the contrast value to, for example, 80% or 60%, the PNG becomes more colorless. The original PNG and the new PNG with the new contrast are immediately shown in the fast preview fields. You can adjust the dimensions of the area where the contrast will be changed with your mouse by dragging the contrast area borders or by moving the entire area to any position on the PNG. For more precise adjustment, you can use the coordinates (x and y – position in pixels) and dimensions (width and height – size in pixels) in the options. Png-abulous!
Png contrast changer examples Click to use
PNG with Greater Contrast
In this example, we increase the contrast of a PNG picture of a red mushroom. We select the entire PNG, which has the size of 580 by 382 pixels with the starting point at the coordinate (0, 0). We set the new PNG contrast to 180%, which is 80% more saturated than the original picture. (Source: Pexels.)
Set the desired contrast value.
Decrease the Contrast of a PNG
In this example, we decrease the high contrast of a PNG photo of light bulbs. In the options, we enter a new contrast value equal to 60%, which makes the pixels in the PNG 40% grayer. The area of the contrast change is equal to the area of the whole PNG photo. (Source: Pexels.)
Set the desired contrast value.
Saturate a Part of a PNG
In this example, we only change the contrast in the top half of the input PNG image. We select the part of the landscape that is above the water (area size is 590 by 210 pixels) and set the maximum possible contrast value for this region equal to 200%. (Source: Pexels.)
Set the desired contrast value.
