Hi guys

I'm blaming the GIF compressor of Gmail... I read some gripes about it but I can't find anything similar to my issue: Gmail cache grows up (almost doubles) the size of my GIF.

An example: my 1.2 MB GIF

and the Gmail one, 2 MB

It's a recent issue because I tested lot of GIFs created until the mid of June and the problem is very limited (the size grows up circa by 10% but not 100%) and noone seems to talk about that problem... I'm about to contact the Gmail support team but I'd like to know if someone is facing the same problem.

Thank you
Stefano
