SnapOtter

SnapOtter is a comprehensive self-hosted image manipulation platform that runs in a single Docker container. It bundles over 45 image tools — resize, crop, compress, convert, watermark, color adjust, vectorize, create GIFs, find duplicates, and more — alongside local AI capabilities for background removal, image upscaling, photo restoration, face enhancement, and OCR.

What sets SnapOtter apart is its pipeline system, which lets you chain multiple tools into reusable workflows with unlimited steps and batch process unlimited images at once. Every tool is also available via a REST API with API key authentication, making it easy to integrate into automated workflows.

As a privacy-first alternative to cloud services like Canva, TinyPNG, and remove.bg, SnapOtter processes everything locally — your images never leave your machine. It runs on AMD64 and ARM64, supports GPU acceleration via NVIDIA, and stores no telemetry unless you opt in.
