How Image Upscaler works
Enlarge an image with fast high-quality browser resampling and optional local AI enhancement. The workflow below reflects the actual inputs, outputs and limits of this specific tool.
- What you provide
- A browser-readable image and an upscale factor.
- What AG File Tools returns
- A larger image produced with local AI when supported or high-quality browser resampling as a fallback.
- Practical limit
- Upscaling cannot recover truly missing source detail. Local AI models can take significant time and memory, especially on phones or large images.
