Logo resolution quality

When saving a png is 300 pi resolution the highest and best quality to send it as?

since png is for digital use rather than print then 300dpi shud be sufficient for all screen related things since 72 dpi is the norm for screen. if i want txt to be v.clear or to use it larger i would go for 300dpi but if speed/file size is a factor i’d stick to 72dpi.
(although technically you can have a png up to 2400 dpi when exporting from indesign and prob other adobe apps)

for a logo i would also send other file formats as well as pngs like eps, jpeg and pdf too… i once posted all file types on a diff topic in the JDF forum.
