What is slimg?

Slimg is a fast image optimization CLI and library that handles conversion, compression, resizing, cropping, and padding for JPEG, PNG, WebP, AVIF, and QOI formats. Built in Rust with bindings for Kotlin and Python, it delivers pre-built binaries across macOS, Linux, and Windows, plus batch processing with parallel jobs for directories. Developers get smaller file sizes using modern encoders like MozJPEG and ravif without manual scripting.

Why is it gaining traction?

It stands out with pipeline ops—resize then convert to AVIF in one go—and format detection from bytes or paths, ideal for image optimization for web, SEO, and Next.js/React apps. CLI commands like `slimg convert images/ --format webp --jobs 4` slash GitHub readme PNG sizes or profile images effortlessly, while bindings make it drop-in for image GitHub Actions or runners. Benchmarks show it crushes single-threaded tools on multi-core setups.

Who should use this?

Frontend devs optimizing images in Next.js or React for faster loads, site owners running image optimization checkers before deploy, or WordPress plugin authors needing lossless PNG/WebP swaps. It's for anyone batch-shrinking GitHub markdown images, profile pics, or web assets without online tools—CLI for scripts, libs for apps.

Verdict

Grab it for quick wins on image GitHub size woes or web perf; 38 stars and 1.0% credibility score signal early days, but solid docs, binaries, and tests make it production-ready for non-critical paths. Skip if you need JPEG XL encoding.
