One more rule that saves re-exports: upload at exactly the recommended size or a clean multiple of it. Platforms re-encode everything; giving them an off-ratio file means their crop and their compression decide how your image looks. (What re-encoding does to your video quality, with side-by-side evidence: smartpoststudio.com/video-quality.)
Resizing one visual for eight platforms by hand gets old. Smart Post Studio schedules to all 8 platforms from your desktop — your original file, no cloud re-encoding on the desktop path. Free plan, no card.
