We introduce AMPhitryon, a novel approach to compress small payloads <100 B (especially 4–20 B). It can be used with existing tools to compress small payloads, while larger payloads can be compressed with arbitrary compressors. AMPhitryon employs a local dictionary that is compiled incrementally in a context-specific setting (e.g., the context could be a network flow or a chat). Our evaluation shows that AMPhitryon achieves higher compression ratios for short messages than existing techniques. It reaches the lowest (best) compressibility ratios (down to 0.30) with the smallest payloads (<20 B).
