Square Solid Black Wallpaper
The square as subject — black squares in art (Malevich says hello), tile patterns, square-format solids. More geometry than gallery filler. Free downloads; contributions welcome.
A black square is either the simplest image possible or a hundred years of art history, depending on who you ask, and this gallery quietly hosts both readings. The picks run from square-format solid fills through tile and grid patterns to pieces that put one sharp black square on a contrasting field. Useful trivia for croppers: most files here are actually wide with square subjects inside them, so desktop users get first pick while phone users should check the shape. Right-click or long-press to save, then set it from your wallpaper settings. Free for personal use.
Common questions
Do black wallpapers actually save battery?
On OLED and AMOLED screens, yes. A true-black (#000000) pixel is switched off rather than dimmed, so it draws no power — and with an always-on display that runs all day the difference is measurable. On an LCD screen it saves nothing, because the backlight stays on either way. Not sure which you have? Our OLED test tool fills the screen with pure black: on an OLED it goes completely dark, on an LCD you can still see the backlight glowing grey.
