A free 4K wallpaper gallery, run by one person, funded by ads and a tiny merch shop.
yumekiru is a free wallpaper site. Around 160 original 4K desktop and phone wallpapers spanning anime and aesthetic styles, cyberpunk, nature, forest, space, ocean, mountains, pastel, cozy interiors and gothic architecture. Everything downloads at full resolution, immediately, without an account.
There's no email capture, no "download in 15 seconds", no watermark, no daily limit, and no account wall. If a wallpaper is on this site, clicking download gives you the file.
Most wallpaper sites are hostile. They gate downloads behind sign-ups, serve you a JPEG that's smaller than the preview implied, bury the actual file behind three interstitials, or upscale a 1080p image and call it 4K. The images themselves are often scraped from somewhere else, with no indication of who made them or whether you're allowed to use them.
This site is the opposite of that by design. One click, full resolution, lossless PNG, a clearlicence, everything made here.
They're generated with AI image models running on hardware in my house, from prompts I write and iterate on. We say that plainly because you deserve to know what you're downloading — but generation is the beginning of the process rather than the whole of it.
A batch produces far more images than survive. Selection is by hand, and it's specifically forwallpaper qualities rather than general image quality:
Roughly nine out of ten generated images fail one of those and don't get published. Survivors are upscaled to 3840 × 2160, checked at full size for artefacts, then titled and tagged manually.
That manual pass is not optional. An earlier automated tagging run on this collection produced a wallpaper titled "Desert Dunes at Night" that was actually a staircase above the clouds, and "Midnight Hills" for a cartoon moon. Every title and tag on the site has since been checked against the actual image by a person, one at a time.
Hosting, bandwidth, a domain and the electricity to generate all this cost money. Two things cover it:
There's also a set of guides covering the practical side of wallpapers: which resolution you actually need, how to set one on each platform, why gradients go stripey, dual-monitor spanning, and where a phone's lock screen will cover your image. These came out of questions people kept asking, and out of problems encountered while making the collection.
The collections pages group the gallery by theme with notes on what each look actually does on a desktop — which ones stay readable under icons, which ones will re-theme your system accent colour, which ones span across monitors well.
Broken download, wrong title, a request, a licensing question, or you just want to say something:[email protected]. Replies usually come within 1–2 business days.
