Qwen Image 2.1 Outpaint

Extend a picture on any side, and Qwen Image 2.1 paints the new area. Qwen3-VL writes the prompt, and my outpaint LoRA keeps your picture in place. Your image goes back on top of the result.

How to use it

1. Load your image.

2. Pick a ratio, or drag the orange handles out. The small button next to the ratios flips portrait and landscape.

3. Optional: finish the sentence in What goes there to say what belongs in the new area.

4. Press Run.

What you need

• AusBoss nodes 2.5.0 or newer. In ComfyUI-Manager, search "AusBoss". Already have them? Update first.

• A ComfyUI build with Text Encode Qwen Image 2.1 (mid-September 2026 or newer).

• The Qwen Image 2.1 models and my outpaint LoRA:

  • qwen_image_2.1_int8_convrot.safetensors → models/diffusion_models · 7.26 GB

  • qwen3vl_8b_int8_convrot.safetensors → models/text_encoders · 9.35 GB

  • qwen_image_2.1_vae_bf16.safetensors → models/vae · 676 MB

  • qwen-image-2.1-outpaint.safetensors → models/loras · 159 MB (v1, for big zoom-outs)

• The sample pictures are in sample_inputs.zip. Put one in ComfyUI/input, or load your own image.

Tips

• Keep the LoRA on. Without it Qwen often shifts your picture. If the file is missing, the run stops at a red LoRA Loader; switch its row off to run without it.

• Say what's missing. The box starts with Also include in the prompt:. Add to it, for example she wears blue jeans. If you delete those words and type your own, the workflow puts them back.

• Pull out at most about your picture's own size on one side per run. More than that can paint a second scene. For more, run again on the result.

• Crop out edges that confuse it. Noise, a frame line or a busy strip along the edge of your picture can make the new area come out strange. Drag the blue handles on Image Crop + Rotate + Pad inward to cut those edges off first.

• Dark corners get extended. A vignette in your photo carries on into the new area.

• Transparent PNG? A person or a scene cut out works. A product cut out with nothing behind it can come back on plain gray, so put it on a background first.

Tilted picture, or something to crop away? Try Qwen Image 2.1 Rotate + Outpaint. About 8 seconds a run on an RTX 5090.

v1.2 (2026-09-30): the padding follows your picture, the seam blends in, and your own words always reach the prompt. v1.1 (2026-09-26): a missing LoRA stops the run, LoRA v2 by default. v1.0 (2026-09-25): first release.
