Image upscaler: uses RealCUGAN (WebAssembly, local CPU) when available (no uploads). If unsupported, it falls back to high-quality resize.
How to Use
- Upload Image: Click 'Choose image' or drag & drop your file onto the page.
- Select Mode: 'RealCUGAN' (AI upscaling) is recommended for best quality; 'High-quality resize' is faster and more compatible.
- Configure: Choose the scale factor (2x/3x) and denoising level (None/Strong/Conservative).
- Process: Click 'Process' and wait for the local AI computation to finish (may take time for AI mode).
- Download: Preview the result and click 'Download' to save the upscaled image.
Tips & FAQ
- Local AI Processing: Powered by RealCUGAN-ncnn-webassembly, this tool runs entirely in your browser. No images are uploaded to any server, ensuring 100% privacy.
- Hardware Requirements: AI upscaling is computationally intensive. A device with a dedicated GPU is recommended. Older devices may experience lag.
- Best Results: The RealCUGAN model is optimized for anime-style images and illustrations, producing the best results for this content type.
- Compatibility: AI mode requires a browser that supports SharedArrayBuffer (Cross-Origin Isolation). If you see an error, switch to 'High-quality resize' mode.
