Icons – clear way of presenting export and import action

I'm looking for a clear way of presenting "import jpg", "import svg", "export jpg" and "export svg" actions.

I want to make it clear by icon look, what is export, what is import (most of the icons which I found online are used interchangeably). Without seeing a tooltip, there is no chance that the user can guess which icon refers to the import action, which to export.

Also, when icons are presented together in a row, it takes a lot of time to understand that one icon refers to the jpg, another to the svg extension.

Any ideas or examples how to handle this?
