I try to reduce texture size after downloading. But it does not works

Answer 1

Size 3 MB, 2.5 MB, 1 MB is the size of file on disk. This is a compressed texture size.

18 Mb is the size of the unpacked texture in memory, i.e. width * height * pixel size.

To reduce the size of the texture in memory and data file size, you can select a compression format suitable for the task and the target platform.

The texture pixel format\compression can be changed in Inspector in Texture import settings panel for each texture.
