The best is if you can Download Adobe Photoshop CC from the official website with 30 Days Free Trial & also you can take students pack which is less costly. It is always effective to Download from the original website with the license.

But once I have downloaded adobe photoshop from this website- Pcriver & I must say my download experience was a great one as I downloaded easily the latest version of Photoshop for free!

This is where you can download for free- Adobe Photoshop CC 2019

Cheers.
