Asset optimization techniques

Apple platforms demand high-quality visuals while maintaining smooth performance. Understanding proper file preparation helps designers create assets that look great without compromising app performance.

Design export guidelines:

• UI elements. Export as PNG with transparency
• Photos. Save as JPEG at appropriate quality (60-80%)
• Icons. Provide PNG at all required scales (@1x, @2x, @3x)
• Vectors. Export as PDF for resolution independence

Each asset type needs specific attention:

• Interface graphics. Keep transparent areas minimal
• Large photos. Consider dimensions and compression level
• Repeated elements. Use the smallest acceptable dimensions
• Background images. Optimize for memory constraints

When preparing design files, focus on the essential visual information. Extra detail often gets lost on device screens while adding unnecessary file weight.
