Frequently asked questions
How do I upscale an image?
Upload the image; the AI enlarges it 4× automatically. Choose 2× if you need a smaller file, compare with the slider and download.
Is the AI upscaler free?
Yes. No sign-up, no watermark and no limit.
Are my images uploaded?
No. The AI model (about 5 MB) is downloaded to your browser and the image is processed on your device.
Why was my image reduced first?
Upscaling is heavy work. To keep it under about a minute, images larger than 1200 px (480 px without GPU acceleration) are reduced before they are enlarged.
Can it restore any photo?
It works best on photos that are small or slightly soft. Very blurry or heavily compressed images get sharper edges, but details that were never captured cannot be recovered.
