Default Couroupted bootanimation

Hellow, iam trying to build my custom bootanimation but the problem is whenever i try to make zip it is couroupted. Note- i want to make custom bootanimation on my phone. Later i camed to know that most of the softwares make zip couroupted and only 7zip can do so. So my question is is there any android app which can do the task of 7zip?
