Frequently asked questions

Does this add new detail like AI upscalers?

No, this tool uses smart interpolation with sharpening, not AI that invents detail. For already sharp photos this gives a good, natural result.

Is my image uploaded?

No. Everything happens in your own browser. Your image never leaves your device and is not stored anywhere.

Is it free?

Yes, completely free, without watermark or account. The site is paid for by ads.

Why in the browser?

PixRust runs entirely in your browser using the Canvas API and WebAssembly. Your image is never sent to a server — all processing happens locally on your device. This means your photos remain private by design, whether they are personal snapshots or confidential documents. There is no account required, no file size limit, and nothing is stored after you close the tab.
