Adjust image brightness & color
Adjust the brightness, contrast and saturation of a photo, then save a PNG. Edit one image at a time. This tool does not upscale or restore resolution.
Choose an image, then create your result.
How to use it
Adjust brightness, contrast and saturation, then save a PNG. Defaults are 0, 100 and 100; saturation 0 makes grayscale. Pixel dimensions and transparency are preserved. Changing a value clears the old result; create a new result to preview it. Original metadata is not copied.
The original stays unchanged. New PNGs may differ in size and color appearance. Visible text, faces and location clues in the image remain.
