How to Use
- Upload or drag and drop an image (JPG, PNG, or WebP up to 10MB) -- on first use, the AI engine initializes automatically in your browser
- Select 2x upscaling (doubles dimensions, faster processing) or 4x upscaling (quadruples dimensions, best for small images needing significant enlargement)
- Enable the 'Enhance & Sharpen' option to apply an AI sharpening filter that brings out fine details and edges in the upscaled result
- Download the upscaled image as PNG (preserves quality and transparency) or JPG (smaller file size), with the new dimensions displayed for reference
Tips
- • 2x upscaling provides faster processing with good quality

AI upscaling enhances details and sharpness while increasing resolution, but it cannot fully restore severely blurry or low-quality source images. Enable 'Enhance & Sharpen' for best results with clearer images.
