What's New in v1.1

Version 1.1 introduces more flexible image output options, a cleaner workflow layout, and a new custom node developed specifically for this project.

🆕 New Custom Node — Save Original Image (JPG / PNG)

We've developed and published our own ComfyUI custom node, Save Original Image (JPG / PNG).

This node allows you to:

  • Save upscaled images in either JPG or PNG format.

  • Preserve the original filenames of processed images.

  • Adjust JPG quality (1–100).

  • Adjust PNG compression level (0–9).

  • Choose a custom output subfolder.

  • Control how existing files are handled: Skip, Overwrite, or Error.

  • Preview saved images directly inside ComfyUI.

The node is now available through ComfyUI Registry and ComfyUI Manager.

🖼️ JPG vs PNG — Choose Your Preferred Output

You can now choose the output format depending on your needs.

PNG — Lossless Quality

  • Preserves image quality without lossy compression.

  • Recommended for archiving, further editing, and maximum image fidelity.

  • Usually produces larger files.

JPG — Smaller File Sizes

  • Uses adjustable lossy compression to significantly reduce file sizes.

  • Recommended for sharing, uploading, and saving storage space.

  • Default quality is set to 95, offering an excellent balance between visual quality and file size.

Note: PNG compression level affects file size and processing time, not visual quality. JPG quality controls the trade-off between compression and image fidelity.

🎨 Improved Workflow Layout

The workflow has been visually reorganized to make it easier to understand and use.

  • 01 — IMAGE INPUT: Dedicated section for batch image processing.

  • 02 — VIDEO INPUT: Dedicated section for batch video processing.

  • Clearer input selection controls.

  • Improved node positioning and connections.

  • Color-coded groups for easier navigation.

  • Visible reminders for folder configuration and batch settings.

Both image and video processing continue to use NVIDIA RTX Super Resolution.

🔧 Improved Custom Node Installation

The workflow now includes the Registry metadata needed for ComfyUI Manager to identify our custom node.

If the node is missing, open ComfyUI Manager → Install Missing Custom Nodes and install Save Original Image (JPG / PNG).

Installation has been tested successfully with both the 1.1.1 and nightly options shown in Manager.
