About this tool
The Halftone Generator divides your image into a grid of cells rotated by the screen angle, averages the luminance inside each cell, and draws a dot whose radius maps that brightness onto your min/max size range — the same principle as a printed halftone screen. Dot shape, angle and colours are all adjustable, and the export is a PNG at up to three times the source resolution. Nothing is uploaded: the whole conversion runs on your device.
