MSE and PSNR Calculator processes image pixels locally in the browser with validated input, Canvas previews, TypedArray calculations, local Web Workers, and browser-generated exports. Images, filenames, pixels, and parameters are not uploaded or stored. Verify important results with a known fixture and document any automatic working-size resize.
