How do I upscale an image with AI?

Upload your image, choose your desired scale (2x, 3x, or 4x), then click "Upscale Image". The AI processes your image entirely in your browser — no upload to any server.

Is this AI image upscaler free?

Yes, completely free with no account required and no watermarks on the result.

Are my images private when upscaling?

Yes. The AI model (ESRGAN) runs 100% in your browser using WebAssembly and WebGL. Your images never leave your device.

What is the difference between 2x, 3x, and 4x upscaling?

2x doubles the image dimensions (e.g. 500×500 → 1000×1000). 3x triples them, and 4x quadruples them. Higher scales produce larger images but take more time to process.

What image formats are supported?

JPG, PNG, and WebP are supported. The result is always saved as a PNG to preserve quality.
