How much can it upscale?

2× or 4×, capped at a maximum output side so results stay reasonable. If 4× would exceed the cap, use 2× or a smaller source image.

Which model should I pick?

Use the photo model for realistic images and the illustration model for art, anime, and flat AI-generated pictures.

Does it keep transparency?

Yes — PNG alpha channels are preserved in the upscaled output.

Where does processing run?

On LrcSong's own infrastructure, so your image isn't sent to a third-party service.
