How does in-browser image upscaling work?

The tool uses multi-pass stepwise bicubic interpolation combined with convolution unsharp masking to reconstruct high-frequency edge details in browser memory.

Are my private photos uploaded anywhere?

No. All pixel interpolation and canvas rendering run strictly inside your browser. No files are transmitted to external servers.

Can this upscale pixel art and retro graphics without blurring?

Yes! Select the "Crisp Pixel Art" scaling engine to preserve needle-sharp square pixels without any smoothing or distortion.
