Practical tips

  • Design at 1280×720 but preview at small sizes — most impressions happen at phone-width, so keep text huge and faces close.
  • Keep critical content away from the bottom-right corner where the duration badge overlays.
  • Export as JPG around quality 80–90 to stay comfortably under 2MB; use PNG only for flat graphics with text.
