As some of you folks might be able to tell. I've recently been playing around with releases/distribution in compose for desktop, as well as proguard, as well as conveyor.

I was finally able to get conveyor to work with proguard. Wrote a bit up here: https://dev.to/coltonidle/compose-for-desktop-app-size-comparison-3d8h

App size comparison in thread

The summary:
1. ./gradlew packageDmg No conveyor.

64.9MB for .dmg
124.1MB for .app (what you get when you open .dmg)

2. ./gradlew packageReleaseDmg No conveyor, but runs proguard.

51.9MB for .dmg
109.9MB for .app (what you get when you open .dmg)

3. ./gradlew packageReleaseDmg No conveyor, but runs proguard with obfuscate.set(true)

48MB for .dmg
105.8MB for .app (what you get when you open .dmg)

4. ./gradlew desktopJar && conveyor make site A regular unproguarded app with conveyor

71.5MB example-1.0.0-mac-aarch64.zip
120.9MB Example.app

5. ./gradlew desktopJar && conveyor make site A regular unproguarded app with conveyor + conveyor's "native library extraction"

62.3MB example-1.0.0-mac-aarch64.zip
123.8MB Example.app

6. ./gradlew proguardReleaseJars && conveyor make site Proguarded app with conveyor

58.6MB example-1.0.0-mac-aarch64.zip
106.3MB Example.app

7. ./gradlew proguardReleaseJars && conveyor make site Proguarded app with conveyor with conveyor's "native library extraction"

49.4MB example-1.0.0-mac-aarch64.zip
109.2MB Example.app

8. ./gradlew proguardReleaseJars && conveyor make site Proguarded and obfuscated app with conveyor

54.6MB example-1.0.0-mac-aarch64.zip
102.3MB Example.app

9. ./gradlew proguardReleaseJars && conveyor make site Proguarded and obfuscated app with conveyor with conveyor's "native library extraction"

45.5MB example-1.0.0-mac-aarch64.zip
105.2MB Example.app

The winner!
I care about initial download size. An app built with conveyor + conveyor's "native library extraction" + proguard + obfuscation (arguably the combo that everyone should aim for) comes in at the smallest download size of 45.5MB. And that contains extra code in there for sparkle (the update framework) that you don't get with the typical gradlew package* tasks (and its also supposed to help with small delta updates). Way cool!

This sorta turned into a bit of app size code golf. If anyone has any other ideas for shrinking things down... let me know!

I've always been curious if R8 would perform better than proguard, but never had the time to experiment with it (on desktop)

[Colton Idle]

i honestly thought that r8 was android only. but can you just use it on any jvm based app? or is it the fact that compose is android-ish so you could possibly use r8? maybe ill add that to my list!

[eygraber]

It can output class files instead of dex so it can be used for regular jvm apps as well - https://r8.googlesource.com/r8#running-r8
