AI detail reconstruction is applied automatically.
🔒 Your image is processed locally. The AI model downloads once, then is cached by the browser. Clear source images still produce the best results.
Frequently asked questions
Does this use real AI detail enhancement?
Yes. A Swin2SR super-resolution model reconstructs edges and texture before the final output size is created.
Why is very large output blocked?
Browsers have memory limits, so the tool caps extremely large output for stability.

Additional questions
Can upscaling restore missing detail?
Upscaling can improve presentation and edge clarity, but it cannot perfectly recreate information that was never present.
Which scale should I choose?
Start with 2× for most images. Use 4× when you genuinely need a larger output and your device has enough memory.
