What Is an Image Brightness Adjuster?

This tool allows you to adjust the brightness of any image. You can make colors, objects, and image details lighter by increasing the brightness, or make all elements of the image darker by decreasing the brightness. Once you upload an image, its default brightness is set to 100%. To increase brightness, you need to enter a value from 101% to 200%, and to decrease brightness, a value from 0% to 99% is required. The program adjusts the brightness within the specified region. It has a rectangular shape and can cover the entire image, only half of it, or only a specific area within the image. You can modify this region in the preview using the mouse or in the options using numerical data. The image with the new brightness can be viewed in the output field and downloaded in PNG, JPEG, or WebP formats. Image-abulous!
