For People restoring old photosAnyone preparing pictures for print

- After
- One template turns the photo into a sharper, larger copy on your own graphics card, with a slider to compare before and after.

Overview
This is an official ComfyUI workflow template that upscales one image with the 7B version of SeedVR2, an open restoration model from ByteDance Seed. You load a photo, choose how many times larger it should be, and it saves one sharper copy plus a before-and-after slider to compare them. ComfyUI offers to download the two model files, about 8.2 GB, the first time you open the template. It suits people who want to rescue low-resolution photos or prepare pictures for print without an online service.
SeedVR2 restores detail in a single step rather than many, and both the template and the model weights are open source.

How it works
From the creator's documentation.
| Step | What happens | Data goes to |
|---|---|---|
| 1 · Model files | ComfyUI offers to download the two model files, about 8.2 GB, the first time | Your computer |
| 2 · Load a photo | You pick the image you want to enlarge | Your computer |
| 3 · Upscale | SeedVR2 7B adds detail and scales the image by the factor you set | Your computer |
| 4 · Compare and save | A slider shows before and after, and ComfyUI saves the larger image | Your computer |
Good to know
Upscale a single low-resolution or lightly degraded photo with the official SeedVR2 7B Int8 graph. The template loads the image, runs the SeedVR2 upscale step and saves the result next to a before-and-after comparison.
Limits
- The two model files take about 8.2 GB of disk space, and the template needs ComfyUI 0.28.0 or newer.
- The template's own description says it targets low-resolution or lightly degraded images. Compare the result with your original before you print it.
