Frequently Asked Questions

What does the AI Image Upscaler do?

The AI Image Upscaler increases the resolution of your images by roughly two times while trying to preserve edges and details. It is useful for improving small images before printing, sharing on social media or adding to presentations.

Is the utoolsy AI Image Upscaler secure?

Yes. Upscaling is performed locally in your browser using a web worker and AI model. Images are not uploaded to utoolsy servers, which helps keep personal photos and sensitive graphics private.

Which image formats are supported for upscaling?

The tool supports common web image formats such as JPG, JPEG, PNG and WEBP. For best results, use clear source images that are not heavily corrupted or extremely small.

How long does AI upscaling take?

Processing time depends on your device and image size. Smaller images may finish in a few seconds, while larger files can take longer as the swin2SR model runs entirely on your hardware.

Do I need a powerful GPU to use this tool?

No dedicated GPU is required, but a modern CPU and browser will provide smoother performance. The model runs on your device, so faster hardware results in faster upscaling.
