Enlarge an image 4× with a super-resolution neural network that adds detail instead of blurring. Inference runs on your device (TensorFlow.js) — your image is never uploaded. Best for small photos, product shots, and avatars.

Best for

  • Enlarging a small or low-resolution image without it going blocky
  • Improving a thumbnail or old photo for print or a bigger display
  • Upscaling artwork or a logo that's only available small

Good to know

AI upscaling reconstructs detail intelligently rather than just stretching pixels — but it can't invent detail that was never captured, so a tiny or very blurry source has limits. It runs on your device; the AI model downloads on first use and is then cached, and large images are bounded by your device's memory.

Frequently asked questions

It uses an AI model to reconstruct plausible detail, which looks far better than a plain resize — but it can't recover information that isn't in the original, so keep expectations realistic for very small or blurry sources.

No — the upscaling runs entirely on your device, so the image never leaves your browser. The AI model downloads once, then works offline.

A moderate upscale gives the best balance of size and quality; pushing much further exaggerates any artifacts already in the source.

The AI model downloads on first use and is then cached, so later upscales start quickly.
