Low Poly is a free browser tool that rebuilds a photo as a mosaic of flat-coloured triangles, the faceted look known as low poly.

How Low Poly works

The tool scatters points across the picture, joins them into triangles and fills each triangle with a single colour taken from the photo. Triangle Density (300–4200, default 1200) sets how many triangles there are: fewer gives a bolder, more abstract result and more keeps more of the photo. Edge enhancement (0–1.8) and Edge sampling (0–48) place more points along edges, and Minimum spacing (2–18px) keeps the triangles from getting too small.

Density channel chooses what the density follows (Luminance, Increase brightness, Red, Green or Blue). Turn on Show wireframe to draw the triangle edges, with Wireframe color and Wireframe thickness (0.5–5px). Luminance, Contrast, Saturation and Gamma adjust the photo before it is triangulated.

Choosing a photo

Photos with clear shapes and areas of colour keep their subject when reduced to triangles. Portraits and landscapes with a simple background work well; very busy photos turn abstract quickly.

Settings worth changing first

Triangle Density (300–4200, default 1200): the number of triangles.
Edge enhancement (0–1.8, default 0.7) and Edge sampling (0–48, default 20).
Show wireframe, Wireframe color and Wireframe thickness (0.5–5px, default 1px).
Analysis Detail: 640, 900, 1200 or 1600 (how much detail is analysed).

Presets

Sharp Facets, Soft Facets, Line drawing and Abstract.

Before you start

What is low poly art?

Low poly art draws a picture from a small number of flat-coloured polygons, usually triangles. It started as a way to keep 3D models light, and is now a graphic style on its own.

How do I get fewer, bigger triangles?

Lower Triangle Density (300–4200, default 1200). A lower Analysis Detail also reduces how much detail the tool looks at.

Can I show the outlines of the triangles?

Yes. Turn on Show wireframe and choose a Wireframe color and a Wireframe thickness (0.5–5px).

What can I export?

PNG or JPEG at 1200, 1800, 2400 or 3200 pixels on the long edge. The photo is processed in the browser and is not uploaded.
