Describe the image you want to generate. Any language is supported, up to 5000 characters.
0/5000Output aspect ratio. The actual pixel size also depends on the resolution tier.
Output resolution tier. Only 1K and 2K are supported. 2K takes noticeably longer to generate.
Background type. transparent outputs a PNG or WebP with a real alpha channel and cannot be used with JPEG. When using transparent, describe only the subject — prompts that mention a background, scene, surface, etc. may produce a non-transparent result.
Output image format. JPEG has no alpha channel, so it cannot be combined with a transparent background.
Rewrites the prompt into a fuller scene description before generating, which noticeably improves quality. Enabled by default (also when the parameter is omitted); pass false to turn it off.
The same seed with the same prompt and parameters reproduces the same image on the same model version. The seed actually used is returned with the result.
A configurable parameter. Defaults to true in the Playground.

Supported formats: JPEG, PNG, WEBP Maximum file size: 30MB; Maximum files: 10
Reference images, 1 to 10 of them. Their order is the order the prompt refers to ("the first image", "the second image"). JPEG, PNG and WebP are supported, up to 30MB and 25MP each. The more references you add the less detail each one keeps, so stay within 4 when fidelity matters. When combining several people or objects into one picture, a landscape ratio such as 3:2 or 16:9 usually works better.
Describe what you want the result to look like. Any language is supported, up to 5000 characters. When a mask is uploaded, describe what should be generated inside the white area instead.

Optional inpainting mask, which switches the request to local-edit mode. A black and white image where white marks the area to change and black stays untouched. It must be used with exactly one reference image, should have the same aspect ratio as that image, and cannot be combined with a transparent background. In local-edit mode the output ratio follows the reference image, so the aspect ratio and prompt rewriting settings are ignored.
Output aspect ratio. Defaults to auto, which takes the aspect ratio of the first reference image and snaps it to the nearest supported ratio. Ignored in local-edit mode.
Output resolution tier. Only 1K and 2K are supported. 2K takes noticeably longer to generate.

Developers can use this capability to build product cutout tools, asset generators, design apps, and automated creative workflows.
Combine Up to 10 Reference Images
Use up to 10 reference images with Qwen-Image 2.1 to create a single coherent result from multiple visual inputs. Combine people into group photos, match models with clothing and accessories, arrange products, or build complete interior scenes from separate assets. This multi-reference capability makes the Qwen Image API well suited to virtual try-on, e-commerce, design, and multi-asset generation applications.
Make Precise Local Edits with Qwen Image 2.1
Control where changes happen instead of regenerating the whole image. Qwen Image 2.1 API supports local editing workflows using circles, painted annotations, or separate masks to identify specific regions. Developers can replace, remove, or add selected elements while keeping the rest of the image intact, making targeted edits easier to integrate into AI editing products.
Preserve People and Products Across Image Edits
Maintain important visual details while transforming an image with the Qwen-Image-2.1 API. The model improves identity consistency for portraits and helps preserve defining product details such as shape, texture, and text. This makes Qwen Image 2.1 practical for portrait editing, branded product visuals, e-commerce content, and other workflows where consistency matters.
