AI Image Upscaler FAQ
Is my image uploaded to a server?
No. The AI model is downloaded to your browser once and all processing happens locally. Your image never leaves your device.
How much can I upscale an image?
Choose 2x or 4x on the page. 2x turns a 500×400 photo into 1000×800. 4x runs the AI model twice for a 2000×1600 result and takes real extra time — the page shows an estimated processing time before you start.
What image formats are supported?
Upload JPG, PNG, or WEBP up to 10MB — up to 1024px on the longest side for 2x, or 512px for 4x (it runs two AI passes). The AI runs tile-by-tile on your device, so larger images take longer; the page shows an estimate before you start. The result downloads as a PNG.
How is this different from normal resizing?
Normal resizing stretches pixels, which makes images blurry. AI super-resolution predicts missing detail, keeping edges and textures sharper.
