Hi there,
I was only guessing that dimensions were the cause, as this typically happens to me on physically small files.
Take a look at this image: https://www.cgdoors.com.au/wp-content/uploads/2019/03/baby-icon.jpg
It’s only 170×135 but it’s a whopping 581 KB, much heavier than larger images that Imagify has compressed. I use the highest compression level usually.
Here’s another example from the same page https://www.cgdoors.com.au/wp-content/uploads/2019/03/fingersafe-icon.jpg
Thanks for offering to take a look.
Regards
Hayden
