So, I've just started using a program called paint.net to crop and save images to be uploaded to TMdb. What I noticed is how, images saved from this program pretty much retain the file size those images had before they were cropped (as saved on my computer before editing/cropping).
Up until now I've been using (MS?) Paint to crop and save images. But they've always been significantly reducing the image file size of images after cropping and saving. I've compared 2 large images on their quality using Paint vs using Paint.net. To me, there doesn't seem to be a difference in quality (or, a difference at all- visually).
The question: does saving images in Paint reduce the quality of images?
Am I stupid for assuming image file size is associated with image quality? Have I been reducing the quality of images by using Paint? I think I've asked this before, but I don't think I've gotten an actual response (or I only asked it in passing/it wasn't the main question/focus of a post).

If the original image is very high quality, 90 is more than enough to create an excellent quality image. 98 has just become a habit for me. The only reason I don't use 100 is that it just makes the image bigger, but someone could argue the same about using 98 instead of 95. Using 100 may not be necessary, but there are no rules about it. Do what you feel is the best.
Unnecessary re-saves are not really helpful, if that's what you are talking about. If would rather start over again from the original image instead of using an image I already edited. But if the quality of the image you are editing is good, it won't be noticed. A common example is fixing a poster on TMDb with the wrong aspect ratio or removing a border with a quick fix. The image on TMDb has already lost some quality, but one extra re-save is usually not an issue. Just remember to always check the final image to make sure it looks good.

At the moment, regardless of whether or NOT an image needs editing (cropping, downscaling, removing text/logo/bars, etc.), my habit is to always open an image on Gimp (and convert to sRGB if the option comes up upon the image being opened) and resave it (to 100) before uploading it to TMdb.
The reason why I do this, is because, I have had at least one instance (that I can remember) where an image has lost its original color/tone after being uploaded EVEN THOUGH (I believe) the image was never edited or resaved on Paint. Therefore, to be on the safe side, I'm opening and saving all images on GIMP before uploading regardless of whether or not it requires editing.
Does that make more sense?

@tmdb24407783 I sometimes open and save images with a perfect ratio just to avoid any possible color issues. Especially with websites I know can be problematic.

Up until just now, I've also been saving an image and then opening it up on a photo editing program (then; MS Paint, more recently; Gimp) and I just realised you could simply copy the image right from the net and paste it into your photo editing program. I tried it out and looks like it makes a difference to the file size (not much, but copying directly onto the program ends up in a smaller file size then saving onto your computer then opening it up on the program- at least with the one original image I've compared on).
Does this matter (to the quality of the image) for TMdb?

I always did that when working with PS. I don’t think it matters much honestly.
