How Image Upscaler works

Upscale images online in your browser with fast high-quality resampling or optional local AI enhancement, without uploading the image to a conversion server.

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.
