These versions are currently only effective for single-person portrait photos.

A fully automated, batch adaptive upscaling pipeline—no manual intervention needed. Just drop your pre-cropped image sets into the input folder and hit “run” to process them all at once. It can losslessly upscale from 240p to 4K, or from 480p to 8K.

This is arguably the strongest portrait restoration and upscaling workflow available, combining the best features of all the leading models. I guarantee you’ll achieve outstanding results.

✨ This new release provides two Workflows for options:

1. “direct_upload_batch_image” lets you upload any number of images of any size directly through the ComfyUI interface.

2. “Upload batch images from the folder” works the same as before: you create a folder inside the “input” directory and drop in the images you want to upscale.

Feel free to choose whichever method you prefer—both yield good results.

🎯 How to Use:
1. Pre-crop the images you want to upscale to the desired dimensions.

2. In ComfyUI’s input folder, create a new directory and drop your images into it.

3. Refresh ComfyUI. In the purple node“Load Images For Loop”，copy the folder path you just created and paste it into the directory field of the purple node..

4.Adjust the value in the red-highlighted setting to match your GPU’s VRAM. This number specifies the resolution. allocated to each tile block. A setting of 1600 P is recommended for 20 GB or more of VRAM.The value must be an integer multiple of 64.

5. Change the save-image name to a path-style format (for example: …/…/output/upscale/4K). This way, all your upscaled outputs will be saved under a consistent name inside a new subfolder of the output directory.

✨Tips:

I. Domains Where This Upscaling Pipeline Excels

①Highly compressed yet otherwise undamaged blurry thumbnails (as low as 240p), which it can restore up to 4K—automatically fixing illogical details so that every element looks natural and true to life.

② Slightly blurred full-body shots (360–480p), which it can losslessly upscale to 6K–8K.

II. Cases Where It Might Also Perform Well

① Images with dirt, smudges, or mild detail distortion

②Pictures full of noise

III. Domains Where It Struggles

①Old photograph restoration

②Images whose native pixels have been badly corrupted

③ Pictures riddled with irregular, malformed color noise

④High-definition images in which the face region alone has a native resolution exceeding 1024P.

IV. How to Check If Native Pixels Are Intact

Open the image and scroll with your mouse wheel to zoom out until you can just make out the subject. Take a screenshot at that zoom level—its resolution will approximate the image’s true, effective native pixel count.
