Save Image MXD

Everyone who's run a 40-image batch in ComfyUI has hit the same annoyance: the stock Save Image node spams your output folder and your preview pane with every single frame. Save Image MXD is the version with a mode switch - save, preview, or save without the viewer noise. It's a small UX fix from a pack whose whole mission is "make the frequently-used nodes less annoying."

What it does

It's an output node: images in, nothing out. The useful part is mode:

• Save + Preview - writes files and shows them in the viewer. The default, matching stock behavior.
• Save Only - writes files but strips the UI preview, so a batch run doesn't flood your viewer with images you're not going to look at. This is the mode you want for bulk passes.
• Preview only - shows in the viewer, writes nothing. Great for A/B-ing before committing.

There's also filename_prefix (the tooltip has the pro tip: you can use a subfolder like tests/my_run to keep outputs organized), and embed_workflow on the optional side, which controls whether PNG workflow metadata gets embedded. Turn it off if you're saving files you'll drag into other tools and don't want the workflow graph baked in.

How it works

Under the hood it's a thin wrapper over ComfyUI's own SaveImage and PreviewImage nodes - no image processing of its own, just a mode switch and an extra knob. That's the appeal: it behaves exactly like the stock node when you want it to, and quietly saves when you don't.

Installing it

Part of the ComfyUI-MaxedOut pack. ComfyUI Manager search Maxed Out, or:

cd ComfyUI\custom_nodes
git clone https://github.com/Maxed-Out-99/ComfyUI-MaxedOut.git

Restart ComfyUI. No extra dependencies, no models to download.

When it's worth it

If you mostly run single images, the stock node is fine and this is a lateral move. If you run batches, renders-for-review, or anything where the preview pane becomes a wall of noise, the Save Only mode is a genuine quality-of-life win - same files on disk, none of the visual clutter. Small node, but it earns its place in a workflow you run daily.
