Verrrrrry high CPU usage

[mnlbox]

I have 4 Lottie animations on my page. I downloaded them from lottiefiles.com but after adding these animations the CPU usage of the page and my system increased a lot. It's always between 80% to 100% and the laptop fan is working constantly but after closing the page everything is OK. Is it normal with Lottie animations? This is just a small personal website with 4 small Lottie animations.
I don't know if it's helpful or not but these are the size of my animation files:

• Animation 1: 167 KB
• Animation 2: 340 KB
• Animation 3: 70 KB
• Animation 4: 215 KB

Any suggestions for improving the page and CPU performance?
