Use photo editing tools to enhance contrast and saturation after upscaling for more impact.

💾 Save as PNG

For wallpapers, save in PNG format to preserve quality without compression artifacts.

🔍 Check Details

Zoom in to verify edges are sharp and no artifacts were introduced during upscaling.

🌄 Landscape Mode

Horizontal photos work best for desktop wallpapers. Portrait photos may need cropping.

🎯 Focus on Subject

Ensure your main subject is centered and won't be covered by desktop icons.
