I used that website to resize. I entered 65x65, but then this website says:
Your file of 125.8 KB bytes exceeds the forum's limit of 48.8 KB for this filetype.
But the website advatar says: 65x65 or 48.8KB, whatever comes first.
And yet my gif is 64x64.
There is a bug in this website
The only way that website can make it work, was using .2x scaledown, but as you can see, my avatar is too small now
