Rice Upscaler
8x AI image upscaler & photo enhancer with DAT & Real-ESRGAN — 100% offline.
Release v1.0.0 • Windows 10/11 (64-bit) • 100% Local Offline Processing
Engineered to Upscale Image Quality at Peak Speed
Native AI engines with intelligent hardware acceleration.
Multi-Engine Cascade & GPU Acceleration
DAT via DirectML for top quality, Real-ESRGAN via Vulkan across NVIDIA/AMD/Intel, Lanczos CPU fallback — auto-selected per GPU.
Scale 1x–8x & Print-Ready DPI
Integer scaling up to 8x super-resolution with Default, 150, and 300 DPI presets for print-ready output.
Target Size Fitting & Multi-Format
Exact output file size (1–24 MB) via binary search. Supports JPG, PNG, WEBP, HEIC with fine-tuned compression.
Batch Processing & 100% Offline
Drag-and-drop batch queue with Long Path & Unicode support. All inference runs locally — zero cloud, zero telemetry.
System Requirements & VRAM Allocation for AI Photo Enhancer
Automatic engine dispatching rules based on detected system hardware.
Automatic Hardware Cascade: VRAM ➔ Active Engine
| VRAM | Engine | Tile Size | Capability |
|---|---|---|---|
| ≥ 8 GB | DAT / DAT-light (DirectML) | 512 | Full-speed DAT inference. 512 tile for up to 8x scaling. |
| 6–7.9 GB | DAT / DAT-light (DirectML) | 256 | Full DAT (≥6 GB) or DAT-light. 256 tile for stable margin. |
| 4–5.9 GB | DAT-light / Real-ESRGAN | 256 | DAT-light (≥4 GB). Cascades to ESRGAN if >10 MP to avoid OOM. |
| < 4 GB | Real-ESRGAN (Vulkan) | Auto | Adaptive auto-tiling via ncnn-Vulkan. Stable on budget GPUs. |
| 1x / No GPU | Lanczos (CPU) | N/A | Instant enhancement/DPI/size fitting. Crash-proof CPU fallback. |
