Issue with uploading GIF head

So I edited this GIF head and added a name on the back of the head https://imgur.com/a/E7zNiB6 and it got denied on the era upload page because of "Sorry the file must be less than 121072 bytes"
Then I uploaded the original head https://imgur.com/a/ja3wtoH and it got accepted
Does anyone know the reason why I'm getting this error? All I did was add a name on the back of the head, nothing else

I have a feeling its either the way you saved it or what you used to save it. Attachment 32498 <- try that
