How to Generate and Edit Images with InvokeAI on Your Own PC

InvokeAI is a powerful, free open-source tool for generating and editing images with Stable Diffusion. Unlike cloud services, it runs on your own machine, giving you privacy, no per-image fees, and professional-grade controls. Here is how to get started.

Step 1: Install InvokeAI

Download the installer from InvokeAI for Windows, macOS, or Linux. The guided setup handles dependencies and downloads a default Stable Diffusion model, so you can begin creating almost immediately.

Step 2: Generate Your First Image

Open the unified canvas and type a detailed prompt into the text field. Add a negative prompt to avoid unwanted elements, then click Invoke. InvokeAI renders your image with smooth, step-by-step previews.

Step 3: Refine with Settings

Adjust the sampler, steps, and CFG scale to control creativity and fidelity. A higher step count often improves detail, while CFG scale balances prompt adherence against artistic freedom. Experiment to find your sweet spot.

Step 4: Edit with Inpainting

Use the inpainting brush to select a region of your image and describe what should replace it. This is perfect for fixing artifacts, swapping objects, or tweaking details without regenerating the whole image.

Step 5: Extend with Outpainting

To expand your image beyond its borders, use outpainting. Select an edge, set the expansion size, and InvokeAI continues the scene naturally, which is great for building wider compositions.

Step 6: Upscale for Quality

Before exporting, run the upscaler to increase resolution without losing sharpness. This makes your images suitable for print, large displays, or detailed zooming.

Final Thoughts

With InvokeAI you get a complete, local AI imaging suite. Master prompting, then explore inpainting and upscaling, and you will produce professional work entirely on your own hardware.
