One automatic AI treatment
High Detail 2× only
The test is locked to RealESRGAN_x4plus and an exact 2× final output so every result is directly comparable.
Starts after upload
There is no redundant Run step. Once the image is selected, the progress bar starts and the AI job begins.
Exact output check
The server verifies the final dimensions. A 1433×2048 source must finish as 2866×4096 before the result is accepted.
Quality first. Compare eyes, hair, text, clothing edges, JPEG softness and small details at 200% zoom. We are deliberately not working on 4× in this stage.
