Image Upscaler
Upscale and enhance image resolution
What is Image Upscaler?
Image Upscaler increases image resolution using AI-powered super-resolution algorithms, adding detail and sharpness rather than simply stretching pixels. Produces cleaner results than traditional bicubic upscaling.
When to use this tool
- Enlarging small images for print without quality loss
- Enhancing low-resolution product photos
- Upscaling screenshots or icons for higher-DPI displays
- Improving the resolution of compressed web images
How it works
Uses a machine learning model (typically ESRGAN or similar) trained on millions of image pairs to predict high-resolution details from low-resolution input. The model runs via WebAssembly or WebGPU in the browser, generating a larger image with reconstructed edges and textures.
