👉 Updated to v3.0 on September 3, 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!

RECOMMENDED: Upload a 1MP version of the image (823x1216, 1024x1024, etc.). If your image is >1MP, consider shrinking it first to 1MP. Uploading an image greater than 1MP doesn't noticeably increase the quality, costs a lot more, and may even result in lower quality! (For example, if your original image is 1024x1536, you may get better results if you first shrink it to 768x1152.)

Notes:

• The max_resolution is capped at 4096 pixels wide or large.

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

Enjoy 😊

*************

Change log:

v3.0 - 3 September 2026 - Increased max_resolution to 4096 px. Added inputs for higher upscale possibilities. Hopefully TA will update ComfyUI soon so that math nodes work. If/when that happens, I'll change it so that you can simply choose 1.5x, 2x, 2.5x, 3x, etc. upscale.

v2.0 - 26 July 2026 - Removed "Blocks to Swap" since no OOM (out-of-memory) errors were encountered. Quality is now at its maximum 🤙

v1.0 - 7 July 2026
