AI generators output around 1–2 megapixels. Prints and POD need far more.
Most AI image generators output images around 1024–2048px. That is fine on screen but too small for posters, canvas prints or print-on-demand products.
Real-ESRGAN upscales faithfully without re-generating, so composition and style stay exactly as you created them.
Download the original: Use the highest-resolution export from your generator.
Upscale to 4K: Or 2x for moderate enlargement.
Fix flaws first: Use the AI Photo Editor for odd hands or artefacts before upscaling.
Style preserved: No re-generation means no unexpected changes.
Print-ready: Enough pixels for posters and POD.
Fix hands too: Pair with our AI hands fix guide.
Can I sell upscaled AI art? That depends on your generator's terms and local copyright rules. ImageLabs adds no watermark and claims no rights.
Why not use the generator's own upscaler? Built-in upscalers often re-generate detail and change the image; Real-ESRGAN keeps it faithful.
Can ImageLabs generate at 4K directly? Yes, the Image Generator can output 4K natively.
Is it free to try? Yes. Signed-in accounts get 10 free credits every day, and new users can try Pro free for 7 days — cancel anytime. No watermark on any plan.
