🖼️ ComfyUI Batch Upscale Without Cropping (Aspect Ratio Safe)

By IT Helper

🎯 What This Workflow Does:

This ComfyUI workflow allows you to batch upscale multiple images of different sizes without cropping or distorting their original aspect ratio. Most batch upscaling tools tend to crop images to fit a uniform size, which causes loss of important visual content. This workflow avoids that by preserving the original composition during upscaling.

🔧 How It Works:

• Loads multiple images from a folder using LoadImageFromFolder [n-suite]
• Feeds them into the ImageUpscaleWithModel node using the model: RealESRGAN_x4plus_anime_6B
• Previews both input and output images
• Saves the upscaled images with the prefix: Bulk_Upscaled_

✅ Nodes Used:

• LoadImageFromFolder [n-suite] – (ComfyUI-N-Nodes)
• UpscaleModelLoader – loads the ESRGAN model
• ImageUpscaleWithModel – performs the actual upscaling
• PreviewImage – visualize before and after
• SaveImage – outputs the processed files
