Frequently asked questions

Is Image Quality Improvement really free and without watermark?

What resolution does Improve Image Quality produce?

Enhance Image Quality generates 1024×1024 (square) by default, but you can choose 16:9 (1344×768) and 9:16 (768×1344) in the picker.If you need more resolution use the "Enhance Image Quality" tool afterwards — upscale any output up to 4× with Clarity Upscaler.

How long does Improve Image Quality take to generate an image?

Depending on the model selected, Flux Schnell generates in 3-5 seconds; Flux Dev in ~10s; Flux Pro 1.1 (premium) takes 30-60s but gives the highest level of detail. You can switch models between attempts without reloading the page.

Can I use the Enhance Image Quality images for commercial use?

Yes, images generated with Image Quality Improvement are yours — no watermark, no attribution required, and with commercial use rights. This applies to Flux (Apache 2.0 license), Stable Diffusion (Stability AI Community License), and open-weight templates in the catalog. Premium hosted templates like Image 4 or Recraft v3 also allow commercial use under our terms.

Does improving image quality censor the prompts?

Improve image quality accepts prompts that most generators reject — Flux Schnell and Flux Dev have almost no filters of their own. We do block illegal content (minors in sexualized contexts, unconsensual deepfakes), but everything else — artistic nudity, violent scenes, political parodies — passes without a problem.
