Frequently Asked Questions
What makes a wallpaper 4K quality?
A true 4K wallpaper has a resolution of at least 3840 x 2160 pixels. This high pixel density ensures that when the image is stretched or cropped to fit your modern smartphone or PC display, it retains absolute sharpness without showing any visible pixelation or blurring.
Do live wallpapers drain my phone battery?
Yes, animated or ‘live’ wallpapers constantly use your phone’s processor and RAM to render the movement, which directly impacts battery life. Using a static, high-resolution dark background—especially on an OLED screen—is the best way to optimize your battery performance.
Why do my app icons look messy over certain images?
If an image has too much detail, high contrast, or busy textures in the areas where your app icons sit, it causes visual clutter. To fix this, you can choose minimalist designs, or use our free editing tools to apply a subtle blur to the background, instantly making your icons readable.
