ComfyUI Workflow Viewer

Drop a ComfyUI image, video, or a workflow .json to instantly see its node graph and extract the embedded workflow. Everything runs in your browser — nothing is uploaded.

What is this?

ComfyUI embeds the full workflow inside every image and video it generates. This viewer reads that embedded metadata and renders the exact node graph — checkpoints, LoRAs, samplers, prompts and all the connections between them — without needing to open ComfyUI. It also works with a raw workflow .json (both the UI graph and the API format).

Supported files

Images (PNG, WebP, AVIF), videos (MP4, MOV, WebM), audio (FLAC, MP3, OGG), 3D (glTF), SVG, and workflow JSON. The same formats ComfyUI can save a workflow into.

Is it private?

Yes. Extraction and rendering happen entirely in your browser — the file never leaves your device and nothing is stored.
