When saving a render a JPG, is it possible to set the compression level?

    Not that I'm aware of. It will always get saved at 100% quality. If you want to lower that, you'll have to do it afterwards in an image editing program like Photoshop, Paint.NET, or GIMP.

    Also, I would suggest saving as PNG or BMP in Studio so you don't lose any quality. Then convert to JPG later on if you need that format. That way you will always have the full quality image to work with in the future.

    thanks. but I am confused. If it always saves at 100% quality like you say, how am I losing quality?!

    JPG uses what's known as lossy compression format. Even at 100% quality, some compression will be applied, which means you are going to lose some image data. You probably won't notice in most cases unless you plan to print the images. PNG and BMP are both lossless, meaning that none of the image data is discarded when you save in these formats. Of course, these formats will result in much larger file sizes than JPG in most cases, which is why' you'll generally want to convert it to a JPG before you upload it to a web site or email it to someone. But again, you can do that later and save it under a different file name. That way you'll always have a copy of the full quality, non-lossy render to work with.
