Fall Background Generator
Make a fall or autumn background: a forest of red, orange and gold trees with light rays and fog, a winding forest path, rolling hills under a big sky, or the hills mirrored in a still lake, all with leaves falling in front. Pick a preset or set your own: the scene, colours, how many trees and how many of them are evergreens, the hills, clouds, light rays, fog and sun, and how many leaves fall, in how many depth layers, how big and with how much wind. Every picture comes from a seed number: the same seed and size always give the same picture, and New seed gives you a fresh landscape. Press Animate leaves to watch them fall in the preview. Choose desktop, 4K, phone, a 16:9 video-call background (for Zoom, Teams or Meet), tablet, square, banner or your own size up to 4096 pixels. It is artwork drawn by our code, not a photograph. Download a PNG or JPG, or a PDF to print. Nothing is uploaded.
100% private — everything runs in your browser. Everything runs in your browser; nothing is uploaded.
The preview is the same picture drawn smaller; Animate leaves moves them in the preview only. PNG and JPG download at the full size; the PDF fits the picture on one page.

How the leaf layers differ
| Layer (of four) | Leaf size (of the long side) | Brightness | Seconds to fall the picture |
|---|---|---|---|
| Layer 1 (farthest) | 0.47 % | 0.66 | 38.1 |
| Layer 2 | 0.68 % | 0.78 | 26.7 |
| Layer 3 | 1.02 % | 0.89 | 20.5 |
| Layer 4 (nearest) | 1.50 % | 1.00 | 16.7 |
Worked out from the rule the tool uses: nearer leaves are bigger, brighter and fall faster, which gives the picture its depth.

Frequently asked questions
Is this a photo?
No. Every tree, hill, cloud and leaf is drawn by our own code from the seed: it is artwork, not a photograph.
What scenes can it draw?
Four: an autumn forest with rows of trees fading into fog, a forest path winding to the horizon, rolling hills with clumps of trees, and the same hills mirrored in a still lake.
Can I use it as a video-call background?
Yes. Choose Video call background (16:9, 1920 × 1080), download the PNG or JPG and pick it as a virtual background in your video-call app. The calm hills preset has no falling leaves, so the picture stays quiet behind you.
How do the leaves look deep?
The leaves are split into one to four layers. Nearer layers have bigger, brighter leaves that fall faster; the table below gives the numbers.
What does the seed do?
It fixes where every tree, hill, cloud and leaf goes. The same seed and size give exactly the same picture, pixel for pixel.
What does Animate leaves do?
It makes the leaves fall and turn in the preview. It stops by itself after 720 frames, when you press Stop, when you change anything and when you switch to another tab. The downloads are always the still picture.
Is this the same as the Thanksgiving background tool?
No. That tool draws a harvest field or a harvest table with pumpkins. This one draws forests, paths, hills and lakes, with no table and no harvest.
How big does the PDF print?
The picture is fitted on one Letter or A4 page inside 10 mm margins, turned to suit its shape. The table below gives the printed size of a 4K picture.
Is it free?
Yes. There is no sign-up, no watermark and no limit.
Is anything uploaded?
No. Every pixel is worked out by JavaScript in your browser. Nothing you type is sent anywhere or saved when you close the page.
