Scan Descreen

FFT ยท Non-Generative

Removes halftone/moire screen patterns from scans via FFT notch filtering โ€” can't invent detail

Upload a scanned or screen-photographed image. The tool finds the periodic halftone/moire ripple in the image's frequency spectrum, notches those peaks out, and transforms back โ€” a classic, non-generative clean-up that can't invent detail.
