Yes. Every Octahedron PNG on this page is free to download.
Can I use these Octahedron PNGs in commercial projects?
The free download is for personal use. Websites, adverts, products, client work and any other business use need a commercial licence; the license page explains how to ask for one. Re-hosting or re-selling the images is never allowed.
Do the images have a transparent background?
Yes. Each file is a high-resolution PNG with a transparent background, so you can place it on any colour or photo. HD 2K and 4K versions can be made on each image page.
Can I edit or recolour the images?
Yes. You may crop, recolour, resize and combine them with your own designs.
