Building Image Compression in Rust with libvips Real Benchmarks, Real Tradeoffs

Rust image compression with real benchmarks, relevant for performance engineering.
Building image compression in Rust with libvips 8.15.1 and Axum, the author found WebP at Q=80 saves only 42.5% vs JPEG's 41.3% on complex photographic content, contradicting marketing claims. mozjpeg offers 10-15% better compression but requires compiling libvips from source, adding operational complexity not justified when libjpeg at Q=80 already covers 90% of use cases. PNG quantization via imagequant (same engine as TinyPNG) achieves up to 36% savings with minimal perceptual loss.
- Evaluate WebP only for graphics or transparency-heavy images; for photographic content, libjpeg at Q=80 is sufficient and avoids mozjpeg's build overhead.
For a Solutions Architect evaluating image processing pipelines, this provides real-world benchmarks and tradeoffs between codec choices and operational complexity, directly informing architecture decisions for cloud-native services.
