FAQ

How does it work?

We use Real-ESRGAN, a state-of-the-art AI model trained to upscale images while adding realistic detail. It works much better than simple bicubic scaling.

What's the difference between 2x and 4x?

2x doubles the resolution (e.g. 500x500 → 1000x1000). 4x quadruples it (500x500 → 2000x2000). 4x takes longer but produces a larger, more detailed result.

Does it work with photos and illustrations?

Yes! Real-ESRGAN handles photos, digital art, anime, screenshots, and illustrations. It's particularly good at restoring faces and fine textures.

How long does it take?

2x typically takes 5-15 seconds. 4x takes 15-45 seconds depending on input size. The first image may be slower as the model loads.

Is my image safe?
