Graphic poster reduction
This tool turns a photo into a bold graphic by reducing it into flat color bands and applying comic-style screening. It pushes images toward shape, contrast, and attitude rather than photographic realism. The effect is processed entirely in your browser without uploading your files.
Unlike an ascii art filter or a dithering pixel art generator, this tool focuses on print-inspired aesthetics. It uses a curated four-color palette, halftone dot art, and bold edge detection to recreate the look of vintage comics, retro posters, and classic pop art portraits.
Tone and color bands
The effect relies on four specific tonal regions: Shadows & Outlines, Dark Midtones, Light Midtones, and Highlights & Base. Choose from curated presets like Vintage Pulp or Neon Nights, or build your own custom palette.
Pre-Exposure shifts the image’s brightness before it is posterized, moving the photo into lighter or darker color bands. Posterize Smoothing simplifies the underlying shapes for cleaner graphic areas, while Band Contrast dictates how sharply the four colors separate from each other.
Halftones and outlines
Comic Dot Size controls the scale of the halftone dot art applied across the midtones. Fine dots create a subtle print texture, while large, chunky dots give a loud, unmistakable comic book energy. It provides a cleaner geometric overlay than the scattered noise of dither pixel art or an ascii art effect.
Outline Detail strengthens edge detection, using your darkest palette color to trace contours and subject shapes. Lower values keep the effect soft and color-led, while higher values create aggressive, inked-edge treatments perfect for graphic novels and poster layouts. Use the Surprise me ✨ button to instantly generate unexpected combinations of palettes, halftones, and outlines.
