Image Editing Policy

I've been reuploading quite a few maps into .pngs, but judging by the quality of the in-game maps, it seemed to me that the original game files were .jpgs themselves. Because of this, I "cleaned" some of the maps to make them clearer and less artifact-y. However, I read over the Image Policy recently and realized that I was not supposed to edit the screenshots. Even if I did count these as cleaning the image, I also wonder if this qualifies as "editing the actual image". Since I wasn't sure, I wanted to ask before I either reverted the images back to the originals, or continue to clean and upload new maps.
Here are the maps I've cleaned, for reference.

Hello Kiwibasket!

Your maps seem fine. As long as the quality is better than the original and it isn't an obvious JPG -> PNG file conversion, it's all good.

The rest of your work around here is great too, so keep it up!

For the maps it's fine, since they're originally jpg like you said. But just to add for other people referencing this post, I would discourage this for screenshots or anything that (should) originally have been lossless.

Thanks for the work so far.
