- Fast: Coil performs a number of optimizations including memory and disk caching, downsampling the image in memory, automatically pausing/cancelling requests, and more.
- Lightweight: Coil adds ~2000 methods to your APK (for apps that already use OkHttp and Coroutines), which is comparable to Picasso and significantly less than Glide and Fresco.
- Easy to use: Coil's API leverages Kotlin's language features for simplicity and minimal boilerplate.
- Modern: Coil is Kotlin-first and uses modern libraries including Coroutines, OkHttp, Okio, and AndroidX Lifecycles.
