Hi There,
I’ve been using transloadit for many months now without problems but since a short while (can’t be sure exactly when) it seems PNG images with transparency lose that transparency after begin uploaded and resized through transloadit.
Check out this image after begin uploaded via transloadit for instance: http://exampleportfolio.com/test_image/in/example_images/2
As you can see it now has a white background. I’ve attached the orignal with transparency…
This used to work like a charm.
