FAQ
Is it really free?
Yes. No limits, no sign-up, and no watermark.
Is my image uploaded?
No. The AI model (about 8 MB) downloads once from Hugging Face and runs in your browser. Your image never leaves your device.
How long does it take?
It depends on your device. With GPU acceleration (WebGPU) in the latest Chrome or Edge it takes tens of seconds; phones or older PCs may take a few minutes. Pick 'Fast' if you're in a hurry.
Can the AI upscale large images?
The AI handles images up to 1,200 px on the long side (600 px without GPU acceleration). Larger images are enlarged smoothly with the 'Fast' method.
How does 4x work?
The AI upscales 2x, then runs again if the size allows, or smoothly enlarges another 2x.
