Size of texture after building too big

Question

This is the log file alt text

I'm trying to make an android game, but the size of images in resources folder is too big after building APK. Size of raw image is about 100kb but after building, size is 678kb. My image is 480x480px so I ticked option override for android with max size is 512, format is RGB compressed etc 4 bits but it does not seem to work. How can I reduce the size of images? Thank for reading.

Raw image is jpg which is using a different compression method. This method cannot be performed at runtime by mobile GPU.

Android devices support some king of compression formats (for Android it's generally ETC, depend on a GPU, you can find more information at the page). It means that the GPU can "eat" those textures in runtime.

If you want to decrease the size you can try to use the Crunched ETC compression. It's a bit better than the simple etc 4 bits but the quality will be slower.

I recommend you use AssetBundle to package these image, it's a very useful way to reduce package size. You can learn it from:
