PrimusThe3rd OK, I finally understand what you mean, 50% is not a compression rate, it is pixel size, right? Sorry, that was not very obvious from your question since so many applications out there have this percentage setting for comression, but I can’t remember any that uses percentage for scaling. I was referring to compression rate in my reply, please disregard it.
As you can see in our settings, Tonfotos has different approach to scaling, it allows you to set destination size, as you noticed. This is very useful in many scenarios when doing batch conversion. Can you please explain your scenario, when relative size would suit better?
