Are these real images?

No — every pattern is pure CSS built from gradients, so it stays crisp at any size and adds no image requests.

Can I change the colours and scale?

Yes. Pick the pattern colour and background, and adjust the tile size to make the pattern denser or larger.

Is anything uploaded?

No. The CSS is generated in your browser and never leaves your device.
