Are these CORTIS wallpapers free?

Yes. Every wallpaper here is free to download, with no sign up and no watermark added by this site.

What size are the CORTIS wallpapers?

They are made for phone screens, mostly around 900 by 2000 pixels, which fits current iPhone and Android screens. The files are the originals, not compressed copies, so they stay sharp on an HD screen.

Can I use them on an iPad or a laptop?

You can, but the phone ones will be cropped on a wide screen. Landscape wallpapers in this page are marked and work better on a laptop or an iPad.
