Coil 3 for Compose & Compose Multiplatform
This reference covers the KMP specifics and two performance guardrails, not the basics of AsyncImage / SubcomposeAsyncImage / ImageRequest / placeholder / error / contentDescription / a shared ImageLoader.
KMP: LocalPlatformContext, not LocalContext
Coil 3 is fully multiplatform — AsyncImage / SubcomposeAsyncImage / rememberAsyncImagePainter are identical in commonMain, with no expect/actual needed. The one swap: use LocalPlatformContext.current, not LocalContext.current (Android-only; a compile error in commonMain). It resolves to android.content.Context on Android and PlatformContext.INSTANCE on other targets.
// commonMain — works on all platforms
AsyncImage(
model = ImageRequest.Builder(LocalPlatformContext.current).data(url).crossfade(true).build(),
contentDescription = "User avatar",
modifier = Modifier.size(48.dp).clip(CircleShape),
)
Singleton setup (KMP): call SingletonImageLoader.setSafe { ImageLoader.Builder(it).crossfade(true).build() } once early in the app lifecycle, or pass an imageLoader explicitly. coil-compose vs coil-compose-core: with coil-compose, AsyncImage without an imageLoader argument uses the singleton automatically; with coil-compose-core, the imageLoader parameter is required (no singleton convenience). Add a platform network engine as needed (e.g. coil-network-ktor3 for KMP).
Two performance guardrails
SubcomposeAsyncImage is significantly slower than regular composition — never use it inside LazyColumn / LazyRow. It creates a subcomposition per item; during scroll that overhead accumulates into visible jank. For custom loading/error states in a list, use AsyncImage with placeholder / error parameters instead — same visual result, no subcomposition.
rememberAsyncImagePainter does NOT infer the display size from layout constraints — without an explicit .size() it loads the image at its original dimensions (a 4000×3000 photo shown at 64dp still occupies the full bitmap in memory → OOM in a 50-item list). Reach for it only when a Painter is strictly required (Canvas, Icon, a custom draw); always pass .size(). Otherwise use AsyncImage, which sizes automatically.
// only when a Painter is genuinely required — explicit size is mandatory
val painter = rememberAsyncImagePainter(
ImageRequest.Builder(LocalPlatformContext.current).data(url).size(Size(128, 128)).build(),
)
Image(painter = painter, contentDescription = null)

# Coil 3 for Compose & Compose Multiplatform
This reference covers the KMP specifics and two performance guardrails, not the basics of `AsyncImage` / `SubcomposeAsyncImage` / `ImageRequest` / `placeholder` / `error` / `contentDescription` / a shared `ImageLoader`.
## KMP: `LocalPlatformContext`, not `LocalContext`
Coil 3 is fully multiplatform — `AsyncImage` / `SubcomposeAsyncImage` / `rememberAsyncImagePainter` are identical in `commonMain`, with **no `expect`/`actual` needed**. The one swap: use `LocalPlatformContext.current`, not `LocalContext.current` (Android-only; a compile error in `commonMain`). It resolves to `android.content.Context` on Android and `PlatformContext.INSTANCE` on other targets.
```kotlin
// commonMain — works on all platforms
AsyncImage(
model = ImageRequest.Builder(LocalPlatformContext.current).data(url).crossfade(true).build(),
contentDescription = "User avatar",
modifier = Modifier.size(48.dp).clip(CircleShape),
)
```
**Singleton setup (KMP):** call `SingletonImageLoader.setSafe { ImageLoader.Builder(it).crossfade(true).build() }` once early in the app lifecycle, or pass an `imageLoader` explicitly. **`coil-compose` vs `coil-compose-core`:** with `coil-compose`, `AsyncImage` *without* an `imageLoader` argument uses the singleton automatically; with `coil-compose-core`, the `imageLoader` parameter is **required** (no singleton convenience). Add a platform network engine as needed (e.g. `coil-network-ktor3` for KMP).
## Two performance guardrails
**`SubcomposeAsyncImage` is significantly slower than regular composition — never use it inside `LazyColumn` / `LazyRow`.** It creates a subcomposition per item; during scroll that overhead accumulates into visible jank. For custom loading/error states in a list, use `AsyncImage` with `placeholder` / `error` parameters instead — same visual result, no subcomposition.
**`rememberAsyncImagePainter` does NOT infer the display size from layout constraints** — without an explicit `.size()` it loads the image at its original dimensions (a 4000×3000 photo shown at 64dp still occupies the full bitmap in memory → OOM in a 50-item list). Reach for it only when a `Painter` is strictly required (`Canvas`, `Icon`, a custom draw); always pass `.size()`. Otherwise use `AsyncImage`, which sizes automatically.
```kotlin
// only when a Painter is genuinely required — explicit size is mandatory
val painter = rememberAsyncImagePainter(
ImageRequest.Builder(LocalPlatformContext.current).data(url).size(Size(128, 128)).build(),
)
Image(painter = painter, contentDescription = null)
```
