Why convert PNG to JSON?
AI image tools such as Stable Diffusion, ComfyUI, Automatic1111 and Fooocus hide the prompt, negative prompt, seed, sampler, steps and model inside the image file. This reads that data out and hands it back as clean JSON you can save, search or reuse.
Why is no prompt found in my image?
Social networks, messaging apps and most photo editors strip embedded metadata when they re-save an image. You need the original file straight out of the generator.
Does this work with photos too?
Yes — any text metadata, comments and software tags found in a PNG or JPG are listed, so you can see exactly what a file is carrying before you share it.
Are my PNG files uploaded anywhere?
No. The conversion runs inside your browser using your own device's processing power, so the file never leaves your computer or phone and nothing is stored on a server.
