Reference images
Upload JPEG, PNG or WebP files up to 10 MB each. Your prompt and uploaded references stay in place when you change models, so you can compare results without uploading them again.
Credits
The Generate button shows the cost before you submit. Credits are refunded if generation fails. Generation time depends on the selected model and service load. Prices shown here are WizImage credits.
