What is Low-Poly Art Generator?

The Low-Poly Art Generator turns photos into geometric artwork using Delaunay triangulation. It detects edges in your image to decide where vertices go, then fills each triangle with the average color from the original photo. The result is the faceted look you see in modern design and digital art.

Vertex count goes from 200 (chunky geometric look) up to 5,000 (close to photographic with thousands of tiny facets). Edge sensitivity controls how many vertices the algorithm puts along high-contrast borders versus flat areas — bumping it up keeps eyes, lips, and shadows sharp even at low vertex counts. One-click style presets (Classic, Sharp, Soft) set sensible vertex and edge combinations for instant good results. Output is available as either a transparent-background PNG or a scalable SVG built from the actual triangle polygons.

How to use

1. Upload a photo (portraits, landscapes, and high-contrast images work best) to use as the source for your low-poly artwork.
2. Adjust the vertex count (more points = finer detail, fewer = more abstract) and edge sensitivity to control where triangles concentrate.
3. Toggle the wireframe overlay if you want the triangle mesh visible, then download as PNG or scalable SVG, or copy straight to the clipboard.

When to use

• Making a stylised portrait for a band cover, podcast art, or social avatar.
• Generating an abstract poster background from a landscape shot you took.
• Producing a faceted product image for a hero section that needs to feel modern without a photo agency.

Result

Upload a portrait photo and set the vertex count to 1,500 for a detailed yet geometric look. You get a low-poly portrait that works well as a profile picture or poster.

FAQ

What's the difference between vertex count and edge sensitivity?

Vertex count is the total number of triangle corners. Edge sensitivity decides where to put them: low sensitivity spreads vertices evenly across the image, high sensitivity clusters them around edges and ignores flat backgrounds. They work together — high count plus high sensitivity gives photorealism, low count plus high sensitivity gives modern abstraction.

Why do faces look blocky even with high vertex counts?

Each triangle is filled with the AVERAGE colour of the pixels inside it, so subtle gradients (skin shading, hair) get flattened. Crank edge sensitivity up so the algorithm puts more vertices around eyes, lips, and jawline, where it matters most.

Can I keep the original colours or restyle them?

Each triangle is filled with the averaged pixel colour from your photo, so by default the palette stays faithful. The colour mode buttons let you restyle on the spot — boost saturation for a punchier Vibrant look, soften it with Muted, or drop colour entirely with Grayscale. For heavier recolouring or posterising, edit the photo in any image editor first, then run it through here.

How big can the source image be?

Up to 20 MB and any reasonable resolution. Bigger images take longer to triangulate; on a typical laptop a 2 MP photo with 1,500 vertices renders in two or three seconds. Phones may take noticeably longer at high vertex counts.

Is the output a vector or a raster image?

Both. Download as a raster PNG when you want a ready-to-use image, or as a scalable SVG built from the actual triangle polygons when you need a vector for print, posters, or further editing. The SVG keeps every triangle as its own coloured polygon, so it scales to any size without quality loss.
