About the Stable Diffusion PNG Info Reader

Most Stable Diffusion interfaces save the full recipe of an image inside the PNG file itself: the prompt, the negative prompt, the seed, the sampler, steps, CFG scale, size and model. It lives in PNG text chunks rather than EXIF, which is why an ordinary metadata viewer shows nothing useful and why you need a PNG info reader to get it back.

Drop a PNG and every text chunk is read in your browser, including compressed ones. Automatic1111 and Forge parameters are split into prompt, negative prompt and a settings table; ComfyUI workflows are searched for the text encoders, the KSampler settings, the checkpoint, the latent size and any LoRAs; InvokeAI and NovelAI metadata are read as well. You can also paste a parameters block directly to parse it.

Copy the prompt or negative prompt with one click, and reuse the seed with the same model, size and sampler to reproduce the image. If nothing is found, the page explains why: uploading to Discord, X, Reddit and most image hosts strips these chunks, and so does converting to JPEG or WebP.
