+# 🦊 RS Upscaler  
+**A node for that combines upscale model loading and image upscaling into a single, compact node with a custom UI.**   
+
+<img width="1547" height="731" alt="Screenshot_2" src="https://github.com/user-attachments/assets/ab1e806f-cf8c-49f9-a76f-1f08f82a62d2" />
+
+### 🔥 Features  
+- **All-in-one** - No need for a separate `Load Upscale Model` node — the model is selected and loaded directly inside the node  
+- **Two-stage upscaling** - First applies the neural upscale model (ESRGAN/RealESRGAN/etc.), then resizes to the exact target factor using the chosen interpolation method  
+- **Tiled processing** - Uses `tiled_scale` internally to handle large images without VRAM overflow  
+
+### Compatibility  
+Tested with ComfyUI core upscaler models including:  
+- `4x_Foolhardy_Remacri.pth`  
+- `4x-UltraSharp.pth`  
+- `RealESRGAN_x4plus.pth`  
+- Any model loadable by `comfy_extras.chainner_models`
