-# ComfyUI_Fast_Preview
+# 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).
+
