Manga Screentone Effect

This tool converts photos into a black-and-white comic panel style using procedural dot patterns and line tracing. The manga screentone effect processes the image locally, turning soft gradients into solid, graphic shapes.

Contrast and thresholding

The tool maps the image brightness to pure black and white. You can use the contrast and brightness sliders to control how shadows separate from highlights. High contrast produces gritty, noir-style shadows, while higher brightness opens up facial features and midtones.

Screentone pattern generation

A halftone dot pattern simulates the traditional screen tones used in manga printing. The pattern size adjusts the visual density, while the pattern angle determines the orientation of the halftone grid. You can also switch to speed lines for action-oriented motion effects.

Line art extraction

An edge-detection step adds inked outlines back over the halftone pattern. The line art thickness slider controls how heavy these edges appear. Thicker lines emphasize character silhouettes and costume details, while thinner lines work better for cluttered backgrounds and architectural shots.

Frequently Asked Questions

It converts a normal image into a black-and-white manga or comic-style illustration using procedural screentone dots or speed-line patterns, tonal thresholding, contrast and brightness controls, and edge detection that strengthens line art.

JPEG, PNG, and WebP. The downloaded image keeps the same format as the original file whenever possible.

No.

A screentone effect recreates the dot or line textures used in manga and comic printing to represent shading, midtones, mood, and movement using black-and-white patterns instead of full grayscale color.

Halftone Dots create classic manga shading with repeated dot patterns. Speed / Hatch Lines create directional line texture that can feel more dramatic, energetic, or action-oriented.

Pattern Size controls the spacing and scale of the screentone. Smaller values create denser, finer dots or lines, while larger values create chunkier, more graphic tone patterns.

Line Art Thickness controls how strongly detected edges are forced into black ink. Higher values create heavier outlines and stronger comic-style structure; lower values create softer, less inked results.

Yes. Once the page has loaded, or if installed as a PWA, it can work offline because the processing is fully client-side.
