The Compression / Quality panel is only active when you've chosen a compressible format to save your image, such as JPEG or WebP. The higher the level, the larger the file size, but the better the quality. The lower the compression level, the smaller the file size, but the worse the quality. Using the slider or the input field, you can set the compression level from 0% to 100%. The Compression / Quality panel allows you to choose how much you want to reduce the size of the image file by reducing its quality. You can also read a good article about HDRI on Wikipedia, here and here. They can capture a wider range of brightness levels, from very dark to very bright. It's the type of images that have 32 bits per pixel, which means they can store a lot more information about the color of each pixel. There are also 16-bit images, which are better than 8-bit, but still not as good as HDR. The more bits per pixel, the more information you can store.

You can't use tone mapping on a regular 8-bit image like PNG, JPEG, etc. The saved image will look the same as it does in the Image Viewer. When you save your image in a non-HDR format, it will keep the exposure that you selected. You can see the exposure change in real time in the Image Viewer. For example, if your image is too bright or too dark, you can lower or raise the exposure to make it better. You should only change this value if you really need to. Most HDR images look good at the default value of 1. The higher the exposure value, the brighter the image. The lower the exposure value, the darker the image. Either the one in the dark zone or the one in the bright zone. A normal screen can't display all the brightness at once, so you have to choose the part of the brightness range you want to see. HDR images contain information about a wide range of brightness, from very dark to extremely bright. You can choose an exposure value from 0.01 to 4 by using the slider or typing the number in the input field above. When you open an HDR or EXR file, you can use the HDRI Exposure panel to change how bright or dark your image looks. You can also do this if your device supports Samsung DeX.
