The Bottom Line
KoalaPic and iLoveIMG are both focused on images, but KoalaPic offers more output formats, a free API, smarter compression, and messaging bot integrations. iLoveIMG counters with additional creative tools like meme generation and AI upscaling, plus a mature mobile app. For pure image conversion and compression with developer features, KoalaPic is the stronger choice. For a broader creative toolkit, iLoveIMG has more options.

Detailed Comparison
iLoveIMG is a well-known image tool suite from the same team behind iLovePDF. It offers conversion, compression, resizing, cropping, watermarking, and more in a clean, approachable interface. Its freemium model gives you a generous set of basic tools with paid plans for higher limits.
KoalaPic shares iLoveIMG's image-only focus but goes further on format support (11 output formats vs. approximately 6), includes a free API with webhook and SSE streaming support, and offers SSIM-based smart quality optimization that automatically finds the best compression ratio. KoalaPic also includes bot integrations for four messaging platforms.
Both are solid image tools. iLoveIMG brings a wider range of editing features and a well-established brand, while KoalaPic offers deeper conversion capabilities and developer-friendly features.
