Question by khayamgondal · Apr 21, 2014 at 03:12 PM · spriteunity 4importing textures

Unity increases size of imported sprites

I had imported a .png (800 x 294) Size 37.2 KB into unity but after importing it shows it size 0.9MB, which is too large than original. I changed the Max Size for 1024 to 512 in import settings which lowers it resolution from original to 512 x 188 with size of 94KB. How does .png size increased this much (from 37.2K to 0.9MB) without any image resolution changes ?

I faced the same issue, 16$$anonymous$$B file (1080X1920) blown up to 9.8 $$anonymous$$B. What I did was, made the same file as POT (Power of Two) to 2048X2048. Now the file size stays around 18$$anonymous$$B even after importing into Unity.

I think the issue here is in the process of padding additional pixels to make your images POT compatible, Unity is blowing up the sizes.

Have you found any answer for this? I'm also facing the same issue, in my case, it is blowing up from 12$$anonymous$$B to 7.9 $$anonymous$$B for an image of resolution 1080X1920.
