Now everything is clear, thanks!

It would be good if things are explained in the backend though.

1. Delete Originals: mark that if custom dimensions are set it won’t work.
2. If possible, add a Delete Backup tool in the admin as well to delete that image-backup folder.

anyway, thanks for your explanations

thanks for the quick response!

After some examinations on another site, I did notice that there are some images in the original media folders which contain the ‘-scaled’ string in them, and after clicking on the “Delete Originals” button they are gone, as you said.

However I also went ahead and did some tests:

1. Keep “Backup Originals” On Local.
2. Upload an oversized image.
3. Check the original media folder, there are 6 images (different dimensions) here, where the full-sized one gets resized down down to the dimension I specified in EWWW. No problem here.
4. However, what I think should happen is, the full-sized file should actually be named ‘XXX-scaled.jpg’, and WP should keep the original oversized ‘XXX.jpg’ here in this folder as well, right? (so that when we click “Delete Originals”, the oversized ones will be removed) But there is not. They are not here in the first place.
5. I then check the ewww image-backup folder, also, there are 6 images here. Now, the full-sized file is indeed that oversized file, and the other 5 thumbnails files are all slightly larger than the ones in the original media folder. (since these are the ‘original’ copies which did not get optimized)
6. I click “Delete Originals”, all 12 images are unaffected.

In summary, I can simply keep “Backup Originals” off, and there wouldn’t be too many confusions. But I still want you to know this potential issue here. If I feel like the entire software makes sense, I would then buy it and add it to my stack. I like EWWW, but I still don’t think I fully understand how it works yet.
