A7iii after editing file size seems smal

I shoot everything in raw. Without cropping and just making a few tweaks when I save the photo as a jpg it only comes out to about 9mb. That seems like a small file to me... Is that what everyone else is seeing on average without getting too crazy editing?

Depends on how much detail, noise, etc. There is no set for size for jpg. A picture of a featureless wall will be smaller than one of a tree line for example, and a high ISO noisier shoot would be larger than a lower ISO of the same scene. Also depends on what quality/compression level you exported to from the raw
