Detect Stable Diffusion Images

Check if an image was made with Stable Diffusion. Analyze metadata and generation patterns. Free AI image detector.

Open AI Image Detector

How it works

Stable Diffusion is an open-source AI image generator that runs locally, making detection more challenging than cloud-based tools. However, Stable Diffusion images still leave detectable traces: common output resolutions (512x512, 768x768, 1024x1024), PNG metadata chunks containing generation parameters (prompt, seed, steps, CFG scale), and absence of real camera EXIF data. Our detector analyzes these signals.

Tips

Stable Diffusion images saved as PNG often embed the full generation prompt in the PNG text chunks — check our String Extractor tool to read raw text data from image files. WebUI interfaces like Automatic1111 and ComfyUI write generation parameters by default.

Frequently Asked Questions

How can I tell if an image was made with Stable Diffusion?

Stable Diffusion images often have generation parameters embedded in PNG metadata, lack camera EXIF data, and use standard AI resolutions. Our detector checks for these patterns along with compression and noise analysis.

Does Stable Diffusion embed prompts in images?

Yes, by default. Most Stable Diffusion interfaces (Automatic1111, ComfyUI) write the prompt, seed, steps, and model name into PNG text chunks. This metadata can be read with our String Extractor tool.

Is Stable Diffusion harder to detect than Midjourney?

Local Stable Diffusion gives users more control over output format and metadata, which can make detection harder. However, the absence of real camera EXIF and characteristic resolution patterns still apply.

Can Stable Diffusion images have fake EXIF data?

Advanced users can add EXIF data after generation, but this is uncommon and usually inconsistent. Our detector checks for metadata coherence — fake EXIF often has mismatched values that real cameras would never produce.
