👉 Updated to v2.0 on July 26, 2026 (see change log at end of Description).

Originally created to upscale videos, the SeedVR2 node in ComfyUI does a great job upscaling images, too.

⚠️ THIS TOOL ONLY UPSCALES IMAGES, NOT VIDEOS!

Costs vary due to unpredictable TA/TH server load, but on average, upscaling a 823x1216 image to 1040x1520 costs about 7-10 credits/tokens.

This pixel-based upscaler will alter the image very slightly—but often for the better!

Tip: Upload a 1MP version of the image (823x1216, 1024x1024, etc.). Uploading an image greater than 1MP doesn't noticeably increase the quality, yet costs a lot more!

Notes:

• The max_resolution is capped at 2048 pixels wide or large.

• If you're using TA, output is subject to NSFW filtering!

Enjoy 😊
