AI Image Upscaler
Upscale images with AI, right in your browser.
Enlarge photos 2×, 4× or 8× with Real-ESRGAN, an open-source super-resolution model. It sharpens edges, rebuilds texture and cleans up blur, noise and JPEG artifacts without uploading anything.

Genuine AI, not resizing
Each pixel is predicted by Real-ESRGAN (realesr-general-x4v3), a neural network trained to restore detail, rather than stretched by interpolation.
Runs on your device
ONNX Runtime Web uses your graphics card through WebGPU where available, and falls back to WebAssembly on your processor.
Compare and save
Check the result with a before/after slider, then save as PNG, JPG or WebP with the exact file size shown before you download.
Privacy: your image is processed entirely inside this browser tab. It is never uploaded, stored or sent to any AI service, and it is cleared from memory when you close it. The model is downloaded from this website and cached by your browser. Results are AI reconstructions: fine details such as text or faces may be invented, so don't rely on them as evidence.
