Why Content-Aware Resize for Twitter/X?
Twitter/X's 3:1 header format is extremely wide — standard cropping of a portrait or square photo will strip away almost everything. Content-aware scaling selectively removes the low-energy background columns first, keeping your subject visible across the full banner width. Your profile header reads well at any viewport size.
