50 MB used assets size became 700+ MB build size

Unity Engine

Hi, I’m new to Unity. I have created a game with just one scene and it’s pretty simple.

1334×750 224 KB

The problem is after I built it, it became 700+ MB like this:

1800×934 167 KB

Size of Xcode Project Folder: 726.45 MB
Total Used Assets Size: 638.6 MB

When I looked at the used assets breakdown list, texture took most of the space at 46.1 MB. I understand that I didn’t optimize it well and I’ll do it soon. However, what confused me is even if I added everything, it still couldn’t more than 50 MB.

The file size after build from Xcode is also large:

790×338 50.3 KB

So, I wonder how the additional 700MB are from? And is there any ways to reduce it? (I already tried everything written in the Unity website (Unity - Manual: Reducing the file size of your build) except the texture because it takes time to recreate many of them. But non of other things help that much.)

Thank you :slight_smile:

Update: Although it’s a pretty large build size. It looks like it’s not that large when compile to IPA

Yes, don’t worry too much about the size of what you upload to Apple. It contains pre-optimised data, basically. Each user will get a fairly small app which varies by device.

Download sizes might even change without you doing anything if Apple come up with some strange, new optimisation.
