I'm a digital art novice, but I can doodle and make decent enough graphics for marketing materials, etc with procreate on my ipad. I'm here as a novel writer, but still need to generate some images, such as thumbnail, cover, banner, ad, and other promotional graphics.
The Tapas images sizes are pretty small..
Thumbnail - 300x300 px
Cover - 960x1440 px
Banner - 1280x460 px
Ad - 280x180 px
How do I resize my graphics to these small sizes without losing all quality? Most advice online seems to say to work as close to the final size as possible, but no one actually creates at these tiny scales, right? I usually start with my screen size (1668x2388 px) or larger as a canvas then crop as needed...
Am I out of luck and just need to redo everything on a smaller canvas...?
