Wallpapers made on your machine.
Every image here is drawn in your browser the moment you load the page, then redrawn at full resolution when you download it — so it is genuinely sharp at 4K, not an upscaled thumbnail. Free for any use, no attribution needed.
About these images
Nothing here is a photograph, and nothing is licensed from anyone. Each wallpaper is generated by a short mathematical routine from a numeric seed — the same seed always produces exactly the same image. That is why the download can be a true 4K render rather than a stretched preview: we simply run the routine again at the larger size.
Because they are generated rather than collected, there are no rights to clear. Use them anywhere, commercially or otherwise, with no credit required.
