ComfyUI Fast Preview

A lightweight, highly optimized custom node for ComfyUI that compresses and previews images directly from the volatile /temp directory. This node minimizes payload size for downstream integrations (like Flow Worker APIs) while displaying the image file size in KB/MB directly on the ComfyUI node interface.

Features

  • Fast Conversion: Prioritizes conversion speed (e.g., WebP method=2).
  • Supports Multiple Formats: WEBP, JPEG, and PNG.
  • Quality Control: Integer slider from 1 to 100.
  • No Clutter: Saves entirely to ComfyUI's temporary folder, preventing disk bloat. Behaves exactly like the core Preview Image node.
  • On-Node File Size: Dynamically injects a UI text display on the node to show the resulting file size (KB/MB).
