This might sound off-topic, but really this is the closest related StackExchange site I could find.
I'm developing a site based on the
Porto theme. The documentation is really nice, but this is left out. This is only minorly relevant.
I'm unsure of some things. There's a lot that's bugging me in:
What size should the uploaded logo be (I have it in vector format)? Should it be in a higher resolution or should it be in it's native resolution (the resolution in which it's going to be shown)? Should I just upload it in the largest available quality, and let it be downscaled (will this affect performance?)? How should my
Apple Retina logo be different?
I have another question regarding site icons - favicons. What resolutions should my apple icons be? In a large resolution or in their native resolution?
What should my
Apple iPhone Icon (recommended: 57px X 57px),
Apple iPhone Retina Icon (recommended: 114px X 114px),
Apple iPad Icon (recommended: 72px X 72px) and
Apple iPad Retina Icon (recommended: 144px X 144px) image sizes be? Should I upload images in the recommended format or just upload a higher-quality one and let it get scaled down (will this affect performance)?
