Stirling Image

Stirling-PDF but for images. 30+ tools and local AI in a single Docker container.

Key Features

• 30+ image tools - Resize, crop, compress, convert, watermark, color adjust, and more
• Local AI - Remove backgrounds, upscale images, erase objects, blur faces, extract text (OCR). All running on your hardware with pre-downloaded models, no internet required
• Pipelines - Chain tools into reusable workflows. Batch process up to 200 images at once
• REST API - Every tool available via API. Interactive docs included at /api/docs
• Single container - One docker run, no Redis, no Postgres, no external services
• Multi-arch - Runs on AMD64 and ARM64 (Intel, Apple Silicon, Raspberry Pi)
• Your data stays yours - No telemetry, no tracking, no external calls. Images never leave your machine

Quick Start

docker run -d -p 1349:1349 -v stirling-data:/data stirlingimage/stirling-image:latest

Open http://localhost:1349 in your browser.

Lite (~1.5 GB) - all image tools, no AI:

docker run -d -p 1349:1349 -v stirling-data:/data stirlingimage/stirling-image:lite

CUDA (~14 GB) - GPU-accelerated background removal, upscaling, and OCR:

docker run -d -p 1349:1349 --gpus all -v stirling-data:/data stirlingimage/stirling-image:cuda

CUDA needs an NVIDIA GPU and Container Toolkit. Falls back to CPU if no GPU is found. See Docker Tags for benchmarks and Docker Compose examples.
