Frequently Asked Questions
How does AI image upscaling work?
AI upscaling uses an advanced AI engine (ESRGAN) trained on millions of image pairs. It learns to predict missing high-resolution details rather than simply interpolating pixels, producing sharper and more detailed results than traditional resizing.
Is my image uploaded to any server?
No. All processing runs entirely in your browser on your device. Your images never leave your device, ensuring complete privacy.
What image formats are supported?
You can upload any format supported by your browser, including PNG, JPEG, WebP, and GIF. The upscaled output is downloaded as a PNG file to preserve maximum quality.
Why is upscaling large images slow?
AI upscaling is computationally intensive. The AI processes the image in small patches. Larger images have more patches to process, so they take longer. Images over 2000px on either side may take significantly more time.
