AI image upscaler
Make a small photo bigger without the blur of normal resizing. The AI adds detail as it enlarges, and it runs on your device.

How it works
- Choose an image up to 1024 px on the longest side. Bigger images are scaled down to 1024 px first.
- The AI enlarges it 4× in small tiles. Drag the slider to compare before and after, and zoom in to check the detail.
- Download 2× free, or 4× with the 24-hour pass.

Questions
Is the upscaler free?
Yes. The 2× download is free with no watermark and no sign-up. The 4× download needs a one-time 24-hour image upscaler pass (US$2.99), which covers any number of photos for 24 hours.
How big can my image be?
Up to 1024 px on the longest side. Bigger images are scaled down to 1024 px first, so the 4× result is at most 4096 px. This keeps memory low enough for phones.
How long does it take?
The AI model and engine are small, about 11 MB in all, and download once. When the browser can use the graphics chip, a photo takes seconds. Without it, a 600 × 800 photo takes about a minute and a half on a laptop, and longer on a phone.
Is my image uploaded?
No. The AI model runs inside your browser, so the photo never leaves your device. Only the model itself is downloaded, once, and your browser keeps it for next time.
