AI Image Upscaler
Upscale images 2x to 8x with Real-ESRGAN neural network — intelligently adds detail instead of just blurring. All processing runs locally in your browser, fully offline.
Model files are bundled with the website. First load caches them in your browser for offline use.
How to upscale an image with AI
- Upload a photo — Works best with clear sources; very tiny or heavily compressed files improve less.
- Load an AI model — Slim (faster) or Medium (more detail). Models download once and can run offline after.
- Choose scale (2x–8x) — Pick Wasm (CPU) or GPU if available.
- Download the upscaled PNG — Neural upscaling adds detail instead of simple stretch.
Why AI upscale here
- Real-ESRGAN in the browser — No cloud upload for inference.
- Multiple scales — 2x, 3x, 4x, or 8x depending on your needs.
- Free to start — No sign-up for local upscaling.
FAQ — AI image upscaler
Is AI image upscaling free?
Yes for local browser upscaling. Models load from this site.
Upscale vs Enlarge tool?
Upscale uses a neural network. Enlarge uses Canvas interpolation — faster but softer.
Why is the first run slow?
The model must download and initialize once. Later runs are faster.
Does upscaling upload my photo?
No. Inference runs on your device.
