Frequently asked questions
Is this AI super-resolution?
No. It is a high-quality Lanczos resampler with an unsharp mask, which keeps edges crisp but cannot invent detail that is not in the source. It runs instantly and entirely on your device.
What is the maximum size?
Output is limited to 8192 px on the long edge; the factor is reduced automatically and the result tells you when that happens.
Are my images uploaded?
No. Everything runs in your browser.
