Every InCosmos Art purchase delivers the full-resolution, unwatermarked 4K–8K original master file directly on your order confirmation screen and by email via download.incosmos.jp. Follow the device-specific steps below to preserve full sharpness without system compression or unwanted cropping.
1. Save the Full-Resolution Original First
- iPhone & iPad (Safari): Open your download link from the order confirmation page or email. Tap the download button to save the master JPG/PNG. If it opens in the Files app, tap the file → Share → Save Image so the uncompressed original is stored in Photos.
- Android & Samsung Galaxy: Tap the download button in Chrome or Samsung Internet. Your master file saves directly to Downloads and appears in Samsung Gallery or Google Photos.
- Mac (macOS): Click the download button to save the 5K–8K master directly to your Downloads or Pictures folder. Keep the file in a permanent folder so macOS retains your desktop assignment across restarts.
2. iPhone & iOS 26 Lock Screen (Depth Effect)
- Open Settings → Wallpaper → Add New Wallpaper → Photos and select your downloaded artwork from iPhone 4K Wallpapers or iOS 26 Wallpapers.
- Use a two-finger pinch to preview framing. Artworks in our iOS 26 collection are composed with upper-third breathing room so the clock and Depth Effect layer cleanly without covering key subjects.
- Tap the … menu in the bottom-right corner and verify Depth Effect is enabled (note: placing lock-screen widgets directly below the clock disables Depth Effect in iOS).
- Tap Add, then choose Customize Home Screen if you prefer a subtle companion blur or solid dark pairing behind app icons.
3. iPhone Duo (Outer Cover & Inner 4:3 Canvas)
- iPhone Duo pairs a tall 1398×2034 outer cover display with an unfolding 2670×1878 (or upright 1878×2670) inner canvas. Browse iPhone Duo Wallpapers for compositions tested across both aspect ratios.
- With your iPhone Duo unfolded, open Settings → Wallpaper → Add New Wallpaper and select your artwork.
- Check the center subject alignment open, then fold the phone to verify the outer cover crop. If you want distinct artworks for cover and inner posture—or a dark battery-saving lock screen—pair 3 or 5 coordinated masters via Collector Editions.
4. Samsung Galaxy Z Fold8 & Galaxy Z Flip8 (Cover + Main)
- Samsung One UI lets you assign independent master files to the cover screen and main folding display—ideal for Galaxy Z Fold8 Wallpapers (1248×1972 cover / 2448×1848 main) and Galaxy Z Flip8 Wallpapers (948×1048 FlexWindow / 1080×2520 main).
- Unfold your device and long-press an empty area of the Home screen → tap Wallpaper and style → Change wallpapers → Gallery to set the main screen master.
- Fold the phone closed, wake the cover screen, and repeat via Wallpaper and style (or Cover screen settings on Z Flip8) to assign your cover artwork independently.
5. iPad & 5K Mac Retina Displays
- iPadOS: Open Settings → Wallpaper → Add New Wallpaper and choose a square-tolerant or 4:3 master from iPad Wallpapers. Rotate your iPad between portrait and landscape before tapping Add to confirm both orientations keep the focal point balanced.
- macOS (Studio Display, MacBook Pro & iMac): Open System Settings → Wallpaper → Add Photo → Choose and select a landscape 5120px+ file from Mac 5K Wallpapers. Set placement to Fill Screen so Retina scaling stays pixel-sharp without stretching.
