How do I convert a GIF to a 300 dpi PDF file?
I'm pretty sure you can just do that via "Save as...".. but you won't obtain layers doing so, that is impossible via a GIF.
Image >> Mode >> RGB Color
Edit >> Image Size (Change the 'Resolution' to 300)
Save As (Save your file as .PDF)
Like said above, you will not gain layers by doing so, and you may lose quality.
EDIT: You do not have to do the first step, but I recommend it
