Questions and answers
Is it really free?
Yes. The online upscaler is free with no sign-up, no ads and no watermark. It enlarges up to 3 photos at a time by 2×. The apps add ×4, batches, PNG and offline use for a one-time price.
Are my photos uploaded to a server?
No. The AI model is downloaded to your browser once and runs on your own device. Your photos are never uploaded, stored or seen by anyone.
How is this different from simply resizing?
Normal resizing stretches pixels, so the photo gets soft and blurry. The AI model was trained on millions of images and redraws edges, textures and fine detail.
Which photos work best?
Small photos: product images, photos from messengers, old phone pictures, scans and crops. Photos that are already large and sharp gain less.
How big can the photo be?
In the browser up to about 4 MP for direct ×2 (bigger photos are reduced first). The apps handle photos up to 16 MP and create results up to 64 megapixels.
Why is it slow on my computer?
With WebGPU (current Chrome and Edge) the graphics card does the work and it is fast. Without it the AI runs on the processor, which can take a minute for a big photo.
