Stretch OLED Battery
On OLED and AMOLED phones every black pixel is switched off, so a pure black wallpaper draws no power where a bright photo would.

Why use a black screen wallpaper?
Let Icons Breathe
An all black background removes visual noise, so app icons, widgets, and clock text read cleanly instead of fighting a busy photo.
Finish a Dark Theme
A full black wallpaper blends seamlessly into system dark mode, dark browser themes, and dark editor colour schemes.
Turn a Screen into a Backdrop
Set it on a spare monitor or tablet for a plain dark background behind photos, product shots, calls, and recordings.
How it works
Get your black wallpaper in 2 steps.
- Choose size and format. Press Download black wallpaper, pick Mobile, HD, 4K, or Square, then choose PNG, JPG, or WebP.
- Set it as your background. Open the saved file in Photos, Gallery, or your desktop wallpaper settings and apply it.
A practical wallpaper guide
A black wallpaper that is genuinely black.
Almost every wallpaper competes with something. A photo fights your icons, a gradient shifts under your widgets, a dark texture turns to visible banding the moment the brightness goes up. A black screen wallpaper does none of that. There is nothing to look at, nothing that clashes, and nothing that changes how your text reads — which is exactly why so many people go looking for one and end up disappointed by what they find.
Why most “black” wallpapers are not black
Search for a black wallpaper and most results are near-black rather than black: a very dark grey, a subtle vignette, a faint fabric or carbon texture, or a slow gradient toward the corners. On a phone screen at low brightness you may never notice. On an OLED panel in a dark room, or on a desktop monitor at full brightness, those choices are obvious — the wallpaper glows faintly where it should be invisible, and the edges of your icons pick up a halo.
Every file generated on this page is filled edge to edge with RGB 0, 0, 0. No logo, no signature, no texture, no gradient, and no compression artefact in the PNG. Sample any pixel and it reads the same value. That is the whole feature.
Choosing the right wallpaper size
Match the download to where it will live. Mobile 1080 × 1920 covers phone lock and home screens. HD 1920 × 1080 fits most laptops and older monitors. 4K 3840 × 2160 suits high-resolution displays and televisions, and stays sharp if the system scales it. Square 2048 × 2048 is for design tools, tablets in either orientation, and layouts that expect equal sides.
Current phones are taller than 16:9, and plenty of monitors are ultrawide, so your device will crop or stretch whatever you give it. With a single flat colour that simply does not matter: a stretched black field is still black. Pick the closest size and let the system fit it. If you would rather choose exact pixel dimensions yourself, the black screen image generator offers the same sizes framed as files rather than backgrounds.
For format, PNG is the dependable default — lossless, so flat black stays exactly flat, and a single-colour PNG is tiny no matter how large the canvas. JPG is smaller still and fine for everyday wallpaper use, although heavy compression can leave faint variation across a flat field. WebP compresses best where the destination supports it.
Black wallpaper and OLED battery life
On an OLED or AMOLED panel every pixel makes its own light, so displaying black means those pixels are off and drawing effectively no power. That is why a pitch black wallpaper genuinely reduces the energy your home screen, lock screen, or always-on display spends — and why the effect grows the emptier your home screen is. It will not transform your battery life on its own, but it is free and it costs you nothing visually.
On an LCD, including most laptops and desktop monitors, a backlight illuminates the whole panel regardless of what is shown. A black wallpaper there is about appearance, not power. If battery is your goal on any panel, lowering brightness and shortening the screen timeout will always beat changing the wallpaper.
Setting a black wallpaper on your device
On iPhone: download the Mobile size, open Photos, select the black image, tap share, and choose Use as Wallpaper. Turn off perspective zoom, and check that wallpaper dimming or the depth effect is not lifting the black. On Android: open Gallery or Files, select the image, and choose Set as wallpaper — or long-press the home screen, pick Wallpapers, then Photos. Some Android skins tint or blur wallpapers automatically; disable that for a true result.
On Windows, right-click the file and choose Set as desktop background, or use Settings → Personalisation → Background with the fill option. On macOS, drag the file into System Settings → Wallpaper, or right-click it in Finder and choose Set Desktop Picture. On a tablet, use the Square or Mobile size depending on how you hold it.
If the result still looks grey rather than black, the device is lifting it — night mode, a custom colour profile, a reduced white point, HDR handling, or an LCD backlight are the usual causes. Compare the same file on a second screen before assuming anything is wrong with the download.
Beyond the home screen
A black wallpaper is useful well outside phone settings: a slide background for a dark presentation, a fill layer in a design mockup, a neutral backdrop on a second monitor during a call, a plain surface behind a product photo, or a screen you leave open to cut glare in a dark room. Because the file is a single flat colour, it can also be used commercially with no licence, no attribution, and no cost.
If you would rather not save anything at all, the black screen tool above turns your browser into the same surface instantly, with fullscreen, cursor hiding, and a 10-hour session. On iOS, the iPhone black screen page gets you edge to edge in Safari, and the white noise black screen adds steady sound to the same dark display for sleeping.

Black screen wallpaper FAQ
What size black screen wallpaper should I download?
Mobile 1080 × 1920 for a phone, HD 1920 × 1080 for most laptops, 4K 3840 × 2160 for a high-resolution monitor or TV, and Square 2048 × 2048 for design tools. Because the image is a flat black field, any cropping or stretching your device applies is invisible.
Does a black wallpaper save battery?
On OLED and AMOLED screens it can. Each black pixel is switched off rather than lit, so the wallpaper itself costs almost nothing to display — the effect is largest on an always-on display or a mostly-empty home screen. On an LCD the backlight runs regardless, so the saving is negligible and lowering brightness matters far more.
Is this a pitch black wallpaper or a dark grey one?
Pitch black. Every file is filled with #000000, RGB 0, 0, 0, edge to edge. There is no gradient, vignette, texture, noise, logo, or watermark — the things that make most so-called black wallpapers look grey on a good display.
How do I set a black wallpaper on iPhone?
Download the Mobile size, open Photos, select the black image, tap the share button, and choose Use as Wallpaper. Turn off perspective zoom and any wallpaper dimming or depth effect so the result stays fully black behind your icons.
How do I set a black wallpaper on Android?
Download the Mobile size, open Gallery or Files, select the image, and choose Set as wallpaper — or long-press the home screen and pick Wallpapers, then Photos. Some Android skins apply an automatic tint or blur to wallpapers; switch that off for a true black result.
Why does my black wallpaper look grey?
Usually the device is lifting it, not the file. Wallpaper dimming, a depth or parallax effect, night mode, a reduced white point, or an LCD backlight can all make pure black read as dark grey. Check those settings first, then compare the same file on a second device.
Is the black wallpaper free to use?
Yes, for anything — personal or commercial. The image is generated in your browser, so there is no account, no upload, no cost, and nothing to attribute.
