What Dot Art Converter does and how it behaves

Upload a photo, logo, or drawing, and this tool redraws it as a grid of circular dots. It samples the image cell by cell and replaces each cell with one dot carrying that region's average color, so dot size and spacing decide how many dots cover the artwork and whether the result reads as texture or as a recognizable picture. The surprise most users hit: this is deliberate abstraction, not lossless conversion. Anything smaller than one grid cell (eyes, small text, thin lines) is averaged into a single dot's color and cannot be recovered. The gaps between dots also expose whatever background sits behind the art.

How the result is produced

Grid sampling

The tool lays a square grid over the image and reads the average color inside each cell, rendering each cell as one circular dot in that averaged color. Halving dot size doubles the cell count in each dimension and roughly quadruples the total dot count, so the same image can read as a handful of blobs or a fine pointillist texture. Judge the artwork at final export size, not at preview zoom.

Color modes

Full-color mode keeps each dot at the sampled color, giving a pointillist look. Grayscale and single-color modes remove hue, so brightness must be encoded some other way, typically through dot size or dot density. This changes the result: dark regions may become large dots, small dots, or dense dots depending on the mode. Compare modes at full size before exporting; the difference is often larger than expected.

Good uses

Turn a logo or icon into a dotted mark for a poster, sticker, or t-shirt print, where the dot texture is the design choice, not a flaw.
Render a photo as pointillist wall art: large dots read well from across a room, small dots hold up when viewed close.
Produce a grid pattern to follow for cross-stitch or bead work, where each dot maps to one stitch or one bead.

Limits and checks

Detail smaller than one grid cell is gone permanently. Eyes, small text, and thin lines are averaged into the covering dot's color, and no color or spacing setting brings them back; only smaller dots help.
Dots are discs, so spacing wider than dot size leaves background visible between them. The same export looks different over white, black, or a colored canvas, so choose the background before judging the result.
Output resolution follows the grid, not the source file: a 4000-pixel photo and a 400-pixel photo give nearly identical dot art at the same settings. In single-color modes, brightness encoded as dot size can also make light and dark regions swap visual weight.

Common questions

Can I convert a face photo and still recognize the person?

Roughly, at small dot sizes, the way a pointillist portrait works. Eyes, mouth, and the overall shape of the face survive; individual eyelashes and strands of hair do not. Keep the face large in the frame, use the smallest practical dot size, and judge the result at final export size rather than at preview zoom.

Why does the background show through between the dots?

Spacing and dot size are independent controls, so wide spacing leaves bare canvas between dots. That is the normal halftone gap, not a rendering bug. Lower the spacing, or raise dot size until the dots meet, for a denser look; widen it for an airier, more textured one. Test both before exporting.
