Overview

Coil

An image loading library for Android and Compose Multiplatform. Coil is:

  • Fast: Coil performs a number of optimizations including memory and disk caching, downsampling the image, automatically pausing/cancelling requests, and more.
  • Lightweight: Coil only depends on Kotlin, Coroutines, and Okio and works seamlessly with Google's R8 code shrinker.
  • Easy to use: Coil's API leverages Kotlin's language features for simplicity and minimal boilerplate.
  • Modern: Coil is Kotlin-first and interoperates with modern libraries including Compose, Coroutines, Okio, OkHttp, and Ktor.

Coil is an acronym for: Coroutine Image Loader.

Translations: 日本語, 한국어, Русский, Svenska, Türkçe, 中文

Quick Start

Import the Compose library and a networking library:

implementation("io.coil-kt.coil3:coil-compose:3.2.0")
implementation("io.coil-kt.coil3:coil-network-okhttp:3.2.0")

To load an image, use the AsyncImage composable:

AsyncImage(
    model = "https://example.com/image.jpg",
    contentDescription = null,
)
