Remacri is best for anime; Real-ESRGAN for realistic photos; Ultrasharp for logos and icons to keep sharp edges.
Switch to "Batch Upscayl" tab, drag in multiple images or a folder. Set output directory and naming, click "Upscayl" to start. Speed depends on GPU performance.
Before batch processing, compare 4x vs 8x time and quality on a single image. Pick the best balance before running the batch.
In Advanced settings: Scale (2/4/8/16x), GPU ID, Tile Size (controls VRAM usage). Advanced users can use the CLI version upscayl-ncnn in automation scripts.
Reduce Tile Size to 128 or 256 to avoid OOM errors on low VRAM — slower but works on 4GB cards.
