What Qwen Image 2.1 accepts
Text to image
A prompt can run up to 5000 characters. With no reference image, the default frame is 3:2.
Reference images
One to ten image URLs switch the request into editing. The default frame then follows the first reference.
Local mask
A mask edits one region. It needs exactly one reference image, and it cannot use a transparent background.
File output
Resolution is 1K or 2K. Formats are PNG, WebP, or JPEG. A transparent background cannot be saved as JPEG.
Ratios and controls
Aspect ratio
Text-to-image supports 1:1, 4:3, 3:4, 3:2, 2:3, 16:9, and 9:16.
Auto frame
Image editing adds auto, which keeps the ratio of the first reference image.
Prompt expansion
Prompt expansion is on by default. Turn it off when the wording in the image must stay exact.
Seed
An integer from 0 to 2147483647 keeps a later run closer to the same result.
