Luban is a memory-safe image loading and optimization library for Android. It functions as an image optimizer and compression tool designed to reduce image file sizes and resolutions while preventing application crashes through the use of pixel limits and downsampling.
The project replicates the specific compression and downsampling logic used by WeChat Moments to ensure images meet social media quality standards. It uses adaptive resolution scaling and dimension-aware strategies to balance visual quality with storage efficiency.
The library covers bulk image processing, format optimization, and memory management. It includes capabilities for batch compression and heuristic quality adjustments to ensure output files do not exceed the size of the original source.
