Simple Image Saver

Production node ID: PortraitImageSaverPreview. The old SimpleImageSaver ID is removed. This node uses the atomic 2.0 export engine. Details.

Actual inputs

  • images: IMAGE tensor to save.
  • output_path: Destination directory; blank uses ComfyUI/output. Relative paths are under that directory; absolute paths are supported.
  • filename: Base filename without extension.
  • suffix: Optional text appended with a dash.
  • file_format: PNG or JPG.
  • jpeg_quality: 0–100, default 95; ignored for PNG.
  • include_metadata: Include workflow prompt/extras when global metadata is enabled. JPEG metadata is a comment, not EXIF; large comments are skipped.
  • unique_filenames: Append a counter rather than overwrite an existing name.

This is an output node with no graph output sockets. It supplies ComfyUI's saved-image UI preview, not a filepath output or an image pass-through. Missing destination directories are created. Batch filenames include an index.

The node defaults to 8-bit output, offers optional 16-bit PNG and an explicit JPEG alpha-background control, and publishes only complete encoded files.
