Common questions
For old family photos, Topaz Gigapixel AI is generally better because its Face Recovery model is more refined and produces natural-looking skin and eyes. Real ESRGAN can work well too, but you may need to tweak settings more and the results can look artificial.
Neither tool has a mobile app. Both require a desktop computer with a web browser (Real ESRGAN) or a downloaded program (Topaz Gigapixel AI). If you need mobile upscaling, look for apps like Remini or Adobe Photoshop Express.
Real ESRGAN is easier to start with because you just upload an image and click a button — no installation needed. Topaz Gigapixel AI has a steeper learning curve because you have to choose between multiple AI models and adjust settings, but it offers better results once you learn.
No, for a casual user who only upscales a few images per year, the subscription is hard to justify. Real ESRGAN is free and good enough for occasional use. Topaz is worth it only if you upscale images regularly for work or a serious hobby.
Yes, both can upscale AI-generated images, but Topaz Gigapixel AI usually produces sharper, more coherent details because its models are trained on a wider variety of image types. Real ESRGAN may introduce artifacts on AI art.
