🧘 Save Images (Dehypnotic)

ComfyUI's built-in Save Image node is PNG-only and names files in a way that's fine until you want to organize output. Save Images (Dehypnotic) is the "I want control over this" version: seven output formats, sequential naming you define, optional workflow embedding, and it passes your images straight through so it drops into any graph without breaking a wire.

How it works

It's pure Pillow - which ships with ComfyUI - so this node adds zero Python dependencies to your install. Each tensor in the batch becomes a PIL image and gets saved with format-appropriate options: JPEG gets quality + optimize, PNG gets optimize plus an optional workflow text chunk, WebP gets lossless (default on) or quality, and every file gets your DPI stamped in. Naming auto-increments by scanning whatever's already in the folder, so re-running a workflow appends instead of clobbering your earlier runs. That's the detail that makes batch workflows tolerable.

The inputs that matter

Everything is technically "required," but most of it is set-and-forget:

• images - the batch; saved one frame at a time.
• extension - png / jpg / jpeg / webp / gif / bmp / tiff. PNG or JPG for sharing; WebP when you care about file size.
• filename_prefix - the default is QIE, which I can't explain and you should change.
• number_padding, number_start, filename_delimiter - gives you QIE_0001.png-style names.
• quality, optimize_image, lossless_webp, dpi - only touch these if file size or a print/DTP use case actually matters to you.
• embed_workflow - writes the workflow JSON into the file (PNG text chunk, WebP XMP). That's the "workflow included" community norm from the ComfyUI ecosystem, automated in one toggle instead of remembered.

One honest caveat on embed_workflow: in the shipped code it pulls the workflow JSON from the node's own attributes or the COMFY_WORKFLOW_JSON environment variable. If you flip it on and see no metadata in the output file, that's the likely reason - it's not the node silently failing.

Outputs: images (passthrough, so you can keep chaining downstream) and saved_path (STRING, one absolute path per line - handy if a later node wants to read the list back). Output node, so it can terminate the graph.

Install

Same pack as the other Dehypnotic save nodes. ComfyUI Manager, search "Dehypnotic Save nodes", or:

cd ComfyUI/custom_nodes
git clone https://github.com/Dehypnotic/comfyui-dehypnotic-save-nodes

Restart. No requirements.txt, and since Pillow is already there, nothing else to install.

Common issues

• Files landing in dated folders you didn't ask for - date_subfolder_pattern defaults to %Y-%m-%d. Clear it for flat output.
• External paths blocked - same pack-wide rule as the MP3 and video nodes: output/ only, unless you whitelist roots in dehypnotic_save_allowed_paths.json (ComfyUI root, config/, or user/config/) or set DEHYPNOTIC_SAVE_ALLOWED_PATHS.
• Heads up: the README announces this repo will be deleted; the maintained home is Dehypnotic/ComfyUI-Dehypnotic, and the class name stays SaveImagesDehypnotic, so your workflows survive the swap.

If all you ever do is drop PNGs into output/, the core node is fine. This one earns its place when you need batch JPG/WebP exports, filenames you can sort, or workflow metadata embedded in the file.
