Frequently Asked Questions

Real-ESRGAN uses deep neural networks trained on millions of images to intelligently add detail when enlarging. Unlike simple resizing, it generates realistic textures and sharp edges.

No. All AI processing happens locally in your browser using ONNX Runtime. Your images stay on your device.

The AI model (2.5-64MB depending on quality) downloads on first use and caches in your browser. Subsequent upscales are faster.

Fast mode uses a smaller 2.5MB model optimized for anime/illustrations. Quality mode uses a larger 64MB model better for photos and general images.

You can upscale up to 4x. However, very large source images may be slow to process or cause browser memory issues. Best results with images under 1000px.

AI upscaling adds some sharpness and detail, but cannot fully recover heavily blurred images. It works best on clear but low-resolution photos.

Works on photos, illustrations, anime, screenshots, and most image types. Results vary based on image content and quality.

AI upscaling is computationally intensive. Processing a 500px image at 4x takes 10-60 seconds depending on your device. Be patient!

Yes! This is ideal for enlarging photos for printing. Upscaling a 1000px image to 4000px provides enough resolution for large prints.

Download as PNG for maximum quality, or JPG for smaller file sizes. JPG uses 92% quality which balances detail and file size well for upscaled images.
