Magento 2.4.3 media/catalog/product/cache growing very hard – each file with many different formats

my media/catalog/product/cache directory is growing very hard.

Digging a bit deeper I see that every picture gets around 30 different files in my cache directory.

In the picture you see the original file on top, and 30 different variants in the cache folder.

We have 80K+ products and adding a lot of products every season …. so my disk space is being filled very quickly.

Are there really 30 different image sizes needed?
Or is there somewhere an option I may have set wrong?

we have Magento ver. 2.4.3-p2
