How to use it

1. Drop in an image.
2. Choose the dot shape and spacing. Smaller spacing gives more detail.
3. Adjust contrast and dot size until the preview looks right.
4. Download the SVG, or a PNG for quick use.

What a halftone is

Printers cannot print shades of gray, so they print tiny dots of one color. Big dots look dark, small dots look light, and from a distance your eye blends them into a continuous picture. That is the newspaper and pop-art look.

This tool does the same thing digitally. Dark parts of your image become large dots and light parts become small ones.

Tips for a good halftone

Start with a picture that has strong contrast and a clear subject. Raise contrast if the result looks flat. Bigger spacing gives a bolder, more graphic look, and smaller spacing keeps more detail.

The result is an SVG made of simple shapes, so it works well for screen printing, vinyl, laser engraving and posters.

What the settings do

Dot spacing

The distance between dots. Bigger is bolder and simpler. Smaller keeps more detail and makes a larger file.

Dot size

How big the darkest dot gets, as a percent of the spacing.

Grid angle

Rotates the dot grid. 45 degrees hides the grid best.

Contrast

Pushes tones apart. Raise it for a punchy look.

Dot color

Black dots on white, white on black, or dots colored from the image.
