How do ultrawide wallpapers work?
Ultrawide monitors use 21:9 (e.g., 3440×1440) or 32:9 (e.g., 5120×1440). Export the exact pixel size for a perfect full-width fit.
PNG, JPG, or WebP?
Use JPG for photos (small size), PNG for crisp graphics/text, and WebP for modern, compact images with great quality.
5 Fun Facts about Wallpapers
Retina likes headroom
macOS happily downsamples a slightly oversized image. A 4K export can still look crisp on 5K because the OS scales down cleanly.
Pixel cushion
Ultrawide changes composition
21:9 and 32:9 crops stretch the scene horizontally—edge details can disappear. Keep the subject near center to survive the wide cut.
Cinematic shift
Phones trim the edges
Lock screens, notches, and gesture bars nibble the top/bottom. Leaving a little breathing room keeps faces and logos out of the danger zone.
Safe area
PNG for art, JPG/WebP for scenes
Flat illustrations stay razor-sharp as PNG; photo wallpapers stay smaller (and often cleaner) as JPG/WebP around 90% quality.
