Frequently Asked Questions
Can upscaling really improve image quality?
AI upscaling adds intelligent detail based on patterns in the image. It won't create new information, but it produces much better results than simple pixel stretching.
What is the maximum output resolution?
The practical limit depends on your input image and device memory. Most images can be upscaled to 4x their original dimensions.
Does this work on compressed JPEG images?
Yes. The upscaler works on any image format. However, heavily compressed source images may show more artifacts after upscaling.
Is my image uploaded during upscaling?
No. The upscaling algorithm runs entirely in your browser. Your image data never leaves your device.
