Reducing assets size on iOS with unity
<p>My android build size is 30mb, but my iOS build size (appstore size) is 400mb. After some researches, I found out that it may be because of assets compression. However, I found really old answers on the forum and I don't know what to do exactly.</p>

<p>I have several PNG images of the size 8192x1080 that I can't shrink because of the quality (I know this is big, but suppose there is no way to reduce or split it) :</p>

<p><a href="https://i.stack.imgur.com/4kN8s.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4kN8s.png" alt="enter image description here"></a></p>

<p>What should I do ?</p>

<ul>
<li>Use a plugin ? Which one ?</li>
<li>Create an AssetBundle ? I never used it.</li>
<li>Make my images 8192x8192 ? When I do so, the size increase to 85mb.</li>
<li>Don't use Sprite type but Advanced type?</li>
</ul>

<p>An other question; when my image is not ARGB but RGB, the second warning message change from PVRTC to ETC1. What is the reason and consequence of it ?</p>

<p>Thanks for the help.</p>
