Assuming the same pixel dimensions, PPI (or DPI, but it really is PPI) makes no difference at all. A 100x100 pixel image at 72PPI is exactly the same as a 100x100 pixel image at 300PPI. No difference at all. All that PPI value is is a meta tag describing what physical dimensions the image should be. If you are printing your image it matters because it ...

Using these files as assets can therefore save 2/3 of the space you ...
