Dynamic Wallpaper Maker

Turn two images into one wallpaper for your Mac. Dynamic Wallpaper Maker gives your own photos and artwork a Light and a Dark appearance in a simple, compact workspace.

CHOOSE YOUR PAIR Drop an image into each side or choose files from your Mac. Import JPEG, PNG, HEIC, and HEIF images up to 20 MB each. Swap the pair with one click and preview both appearances before exporting.

EXPORT, SHARE, OR SET Save a single HEIC with File → Export Wallpaper, share it through macOS, or use Set as Wallpaper to save and apply it to the display containing the app window.

PICK UP WHERE YOU LEFT OFF Your current draft stays on your Mac for your next session. Undo changes, replace either image, and reconnect a source file if it becomes unavailable.

KEEP YOUR IMAGES LOCAL Images are processed on your Mac. Your original files stay unchanged, and exported wallpapers do not copy source location or camera metadata. There is no account, advertising, tracking, or automatic uploading.

The Light image determines the output size. The Dark image is centered to fill the same area, so different proportions may crop its edges. Use Preview to check the result.

macOS controls wallpaper appearance switching. After applying or adding the HEIC in System Settings → Wallpaper, choose Automatic if available. Support and wallpaper settings vary by macOS version.
