Luban 2 is an Android image compression library written in Kotlin that reverse-engineers WeChat Moments' compression strategy to produce similarly small, high-quality images. It uses Kotlin Coroutines for async processing and TurboJPEG for efficient encoding, with adaptive resolution and bitrate strategies.
Use cases
- compress photos before uploading from an Android app
- reduce image file sizes to match WeChat Moments quality
- downscale high-resolution camera photos to save bandwidth
- handle very long screenshots or panorama images without OOM
- preserve PNG transparency while converting large PNGs to JPEG
When to choose
- you build Android apps that upload user photos and need small, visually good results
- you want compression output close to WeChat Moments
- you need coroutine-based async compression with robust edge-case handling
When to avoid
- you need image compression on platforms other than Android
- you need general-purpose image editing beyond compression and resizing
- you require exact byte-identical WeChat compression output
