ComfyUI
Full workflow graphs
Reads the embedded node workflow and resolves the effective prompt, model, sampler and seed from the graph.
Free Tool
View Stable Diffusion & ComfyUI metadata from any PNG.
Drop a generated PNG below to see its prompt, negative prompt, model, sampler, seed and full workflow — parsed instantly in your browser. Your image is never uploaded anywhere.
Got a whole folder of these? Image MetaHub searches your entire local library the same way — for free.

Raw metadata (JSON)
Got a whole folder of these?
Image MetaHub searches your entire local library by prompt, model, LoRA and seed — instantly, without uploading anything.
ComfyUI workflows using very custom or "bridge" nodes (widget-relay helpers, uncommon sampler/scheduler
selectors, etc.) may only resolve partially — the raw JSON above always has everything that was embedded.
Hit a workflow that should have worked?
Open a GitHub issue
with the file attached and we'll take a look. For guaranteed complete, structured metadata on every save, use the
MetaHub Save Node
in your ComfyUI workflow instead of the standard Save Image node.
Works with every major AI image generator.
The same parser that powers Image MetaHub's desktop library — reads embedded PNG metadata, no guessing.
Automatic1111 / Forge
Standard parameters block
Prompt, negative prompt, steps, CFG scale, sampler, seed, size, model hash and LoRAs.
InvokeAI
Structured JSON metadata
Positive/negative prompt, model, VAE, scheduler and generation mode.
More formats
SwarmUI, Fooocus, SD.Next, Easy Diffusion, Draw Things
And Image MetaHub's own MetaHub Save Node payload for ComfyUI.
Frequently asked questions
Does this upload my image anywhere?
No. The PNG is read and parsed entirely in your browser using JavaScript. It's never sent to a server.
What is PNG metadata for AI images?
Stable Diffusion, ComfyUI, A1111, InvokeAI and Forge embed the prompt, model, seed, sampler and (for ComfyUI) the full node workflow directly inside the PNG's text chunks.
Why does it say no metadata was found?
Some tools strip metadata on export, and social/messaging apps often re-encode images and remove it. Screenshots never had it to begin with.
Save Image node vs. the MetaHub Save Node?
ComfyUI can reopen the workflow from any PNG it saved — that's built in, not specific to any node. The MetaHub Save Node additionally writes clean, pre-resolved fields (prompt, model, seed, tags, notes, analytics) so tools don't have to reverse-engineer the graph.
Got a folder full of these?
Image MetaHub searches your whole local library by prompt, model, LoRA and seed — instantly, without uploading anything. Free to start.
