Hi. I’m very new to this and struggling with dpi and file size. In order to upload from canva at 300dpi I am having to toggle the size bar as far as it goes which is resulting in files which are 20+ MB. My designs are the correct size (A size) which I use the Canva upscale tool on. Often I’m using images from midjourney and sometimes chat gpt. I have watched the tutorials but still struggling. Any guidance on how to use Canva to get the correct size files would be hugely appreciated. Thanks.
