AI Image Upscaler

Enhance blurry or low-resolution images with AI — sharper details, more pixels, no uploads.

1. Upload Your Image

Drop an image here or click to browse

Supports JPG, PNG, WebP — processed locally

2. Choose Scale Factor

Large images process in tiles. Processing may take 30-90 seconds.

How It Works

  1. Upload any blurry or low-res photo.
  2. AI enhances locally via WebGL.
  3. Download enhanced result.
100% Private No Sign-up WebGL Powered

Best results with:

  • Old compressed photos
  • Screenshots and digital art
  • Product images for web

FAQ

Is my image uploaded anywhere?

No. TensorFlow.js runs in browser. Your image never leaves your device.

What's the difference between 2x and 4x?

2x doubles dimensions. 4x quadruples. More detail but slower processing.

Why is processing slow?

Large images process in tiles. Speed depends on your GPU availability.

What AI Upscaler Does

Super-resolution networks predict missing pixel details. Edges sharpen. Textures enhance.

WebGL accelerates TensorFlow.js. GPU processes faster than CPU.

Under the Hood

Neural networks trained on photo datasets. UpscalerJS loads model once. Cache speeds repeats.

This architecture enables local processing. No server roundtrips required.

Edge Cases

Very abstract images may show less improvement. Photos work best. 4x on large images takes time.

Memory limits may affect huge files. Keep under 2000px for best performance.
