Issue with file size?

I've been looking into how to reduce the file size of my game (which is a pretty tiny game designed for a website or mobile app). The total of all my assets looks to be 6.4 mb but my build size is 75 mb for some reason and I can't find an explanation for why. How do I fix this?

Uncompressed usage by category (Percentages based on user generated assets only):
Textures 5.7 mb 89.4%
Meshes 0.0 kb 0.0%
Animations 0.0 kb 0.0%
Sounds 0.0 kb 0.0%
Shaders 32.2 kb 0.5%
Other Assets 441.0 kb 6.7%
Levels 0.0 kb 0.0%
Scripts 177.3 kb 2.7%
Included DLLs 0.0 kb 0.0%
File headers 44.6 kb 0.7%
Total User Assets 6.4 mb 100.0%
Complete build size 74.9 mb

 

Steps to success:

- understand what you can and cannot control

- make a blank project with a single blank scene

- build that to the desired target

How big is it?

The difference between a blank project's final build size and your project is how big your final assets are. That will be the size you can control.

About the fastest way I have found to make a project and avoid all this noise is to create the project, then as soon as you see the files appear, FORCE-STOP (hard-kill) Unity (with the Activity Manager or Task Manager), then go hand-edit the Packages/manifest.json file as outlined in the above post, then reopen Unity.

Sometimes the package system gets borked from all this unnecessary churn and requires the package cache to be cleared:

Ahh that's what I figured, thank you! I'll check these out and see how far I can get it down before it becomes essential Unity data. I knew that Unity was going to have a lot of extra features built into the final game build that I wouldn't need but I wasn't sure how to access them, so I appreciate the links!
