Image-To-Image

This example edits an input image with Qwen/Qwen-Image-Edit using the image_edit.py CLI.

Local CLI Usage

python image_edit.py \
  --image qwen_bear.png \
  --prompt "Let this mascot dance under the moon, surrounded by floating stars and poetic bubbles such as 'Be Kind'" \
  --output output_image_edit.png \
  --num_inference_steps 50 \
  --cfg_scale 4.0

Key arguments:

• --image: path to the source image (PNG/JPG, converted to RGB).
• --prompt / --negative_prompt: text description (string).
• --cfg_scale: true CFG scale for Qwen-Image-Edit (quality vs. fidelity).
• --num_inference_steps: diffusion sampling steps (more steps = higher quality, slower).
• --output: path to save the generated PNG.
