Safe margins
Keep important text at least 5% from each edge on landscape and square images and 8% on portrait ones. For vertical video covers, keep text out of the top 12% and bottom 20%.
File type and quality
itistitle exports PNG, which stays sharp on text. Most platforms re-compress uploads, so start with the full export size rather than a smaller one.
