I want to put country flags on my map (many flags) but for obvious reasons I cant just put any flag I find on google because of the file size limit, is there any page where I can get small svg flags for the map?and if theyre already in PixelArt format I guess that would be better so I dont have to import the file to inkscape and then turn it into a Pixel Art.

Maybe try to manually draw it? I know it wont look as fancy with more complicted flags, like countries like Sri Lanka have, but if you are struggling with file size, its your only real option.

I mean, currently Im on 1,36 MB but I dont want to start adding flags and then reach the point where I cant add more with some nations still without flag so im not sure, so I wanted to know if there was a site where I can download the small flags or if I can just resize it somewhere, download it, import it to Inkscape and then use the PixelArt option on inkscape to make it a path but im not sure

I don’t have Inkscape open so I cannot 109% tell you the direct path the take, but import the image in, and go to Path>Trace as Bitmap.
