recently I am start a longboard deck review website. In which I cover all of the skateboard or a longboard related blog or new on it. so a few day ago I am attend an skate event in UK and take best shot pic or video for my blog so but i am a little bit confused due to heavy image size it will take time to open and upload on a WordPress site. so now i want to reduce my image size to convert my jpge image into png is this practice is good or not?. or is it recommended?
