Like the title, what the personalized logo size or proportion?
Hi AdamoSrl
The QuickSupport and QuickJoin logo size is 100 x 270.
The Host module is 100 x 480.
The tool will automatically resize larger images to a best fit without cutting the logo.

A few useful things to know;
a) If your logo's size is even one pixel out the resizing will result in it being a bit blurry in the app.
b) Your graphic should have a transparent background if you want the logo to match your QuickJoin, Quick Support or Host app's chosen colour scheme and for it to match the banner on the app download web page (where it also appears).
c) In Photoshop CC if you choose the PNG save option 'Largest file size (fastest saving)' it won't upload successfuly. Select 'Smallest file size (slowest saving)'.
