SimpleImageSaver

SimpleImageSaver writes images to disk with a few essential controls: choose PNG or JPG, decide whether to embed metadata, and add a custom suffix to the filename.

Inputs

image – The photo to save.
filename – Base name for the output file. Combine with FilenameAppendSuffix if you need version tags.
format – PNG for lossless output or JPG for smaller files.
quality – JPEG quality (ignored for PNG). Use values between 1–100.
embed_metadata – When True, include ComfyUI metadata in the file.
suffix – Optional text appended before the extension.
output_dir – Destination folder. Leave blank to use ComfyUI’s default save path.

Outputs

filepath – The path of the saved file for logging or downstream reference.
image – Pass-through of the original image so you can continue processing if needed.

Where It Fits

Use SimpleImageSaver for quick exports during iteration: saving contact sheets, before/after comparisons, or intermediate passes without configuring the full ComfyUI save stack.

Tuning Tips

Stick with PNG when you plan to revisit the file; choose JPG with quality around 90 for client previews or web use.
Set a default output_dir to keep test renders separate from final deliveries.
Pair the node with FilenameAppendSuffix or WorkflowConfig to generate consistent naming.

Troubleshooting

File not appearing – Confirm the output_dir exists and that ComfyUI has write access. The node won’t create missing directories.
Metadata missing – Make sure embed_metadata is toggled on and that downstream tools read PNG/JPG EXIF data.
Suffix duplicated – Leave the node’s suffix empty when you already modified the filename upstream.
