Questions

  • What is AI upscaling?

    Upscaling increases image resolution using AI to add detail. 2x doubles dimensions, 4x quadruples them (e.g., 500x500 becomes 1000x1000 or 2000x2000).

  • What's the maximum input size?

    Images up to 1024x1024 pixels work best. Larger images will be resized before upscaling to ensure browser performance.

  • Is processing really in my browser?

    Yes, all AI processing happens on your device using WebAssembly. Your images never leave your browser.

  • How long does upscaling take?

    Processing time depends on image size and your device. 2x typically takes 5-15 seconds, 4x takes 15-30 seconds.

  • Does 4x always look better?

    Not always. 4x creates larger files and may add artifacts on complex images. 2x is safer for web use, 4x for print-quality needs.
