FAQ
Useful limits and answers
Is my photo uploaded to a server?
No. The AI model runs inside your browser with WebGPU or WebAssembly. The image never leaves your device.
Which upscale factors are supported?
2x and 4x. A 1000x800 photo becomes 2000x1600 or 4000x3200 with reconstructed detail instead of blurry stretching.
Is the AI upscaler free?
Yes. The tool is free, with no sign-up, no watermark, and no usage limits beyond what your device can handle.
What happens on the first run?
The browser prepares a small AI model (about 5 MB) once and caches it locally. Later runs start instantly and also work offline.
How large can the input image be?
The tool automatically keeps the output within a safe browser memory budget and tells you if the input was reduced first.
Does it work for anime and illustrations?
Yes. The general Real-ESRGAN model handles photos, product shots, screenshots, and illustrations well.
