This low poly generator is an image converter that rebuilds any picture out of flat-colour triangles, the faceted, crystalline style that early 3D games made famous and modern design turned into an aesthetic of its own. Drop a photo on the page and it is polygonized immediately: the tool finds the edges in the image, lays a mesh of triangles over it, and fills each triangle with the average colour of the pixels underneath. The result reads as the original picture at arm's length and as pure geometric art up close. Everything runs free in your browser, online but with nothing uploaded, and the download comes out at the full resolution of the photo you loaded.
Two sliders shape the mesh live. Detail sets how many triangles the picture is built from, and the number beside the slider shows the live count: the low end gives a few hundred bold polygons for a heavily stylized, abstract look, the top end thousands of fine triangles that keep faces and small objects recognizable. Edge focus decides where those triangles go. The tool runs edge detection over the photo once, so it knows where the real lines are - the outline of a jaw, the rim of a building, the horizon - and this slider moves triangles from the flat areas onto those edges. High values trace the subject sharply while skies and walls stay as large calm facets; at zero the mesh spreads evenly like a jittered grid pattern.
The mesh itself is deliberately reproducible: the same photo with the same settings always builds the same triangles, so you can come back tomorrow and recreate today's result exactly. When you want a different arrangement of the same style, the New pattern button reshuffles the mesh into a fresh variation, and the compare button in the corner shows the original photo for as long as you hold it.
The algorithm is the classic three-step low poly pipeline, done properly. First a Sobel edge detection pass measures the gradient at every pixel and keeps the strongest point in each small cell of the image, which is what lets the edge focus slider place points exactly where the picture has structure. Second, those points - plus a jittered grid, the four corners and a row of anchors along each border, so the rectangle is covered without stretched sliver triangles - are joined by a Delaunay triangulation, the mesh that mathematically favours well-shaped triangles over thin ones. Third, every triangle is filled with the true average colour of the source pixels inside it, not just a single sampled point, so the art stays faithful to the photo's tones. While you drag a slider the preview uses a fast colour estimate; the moment you release it, the exact pass runs.
The download is not a stretched screenshot of the preview. The generator keeps the mesh as geometry and redraws it as vectors at the source resolution, so every facet edge in the saved file is razor sharp whether your photo is 800 pixels wide or a 40 megapixel scan. Save the polygon art as PNG for perfectly clean edges, or as JPG or WebP for a smaller file; a JPG you loaded downloads as a JPG by default, and you can rename the file right on the result screen.
Low poly art earns its place anywhere a raw photo would look too literal. A landscape becomes a striking desktop or phone wallpaper; a portrait becomes a distinctive pfp - run your photo through the generator, then crop it square or round with the avatar cropper or frame it for a server with the Discord profile picture cropper. The style also works as a poster maker for prints, as a YouTube thumbnail treatment, and as a website hero background where the geometry adds texture without stealing attention. Landscapes and portraits with a clear subject polygonize best; a busy picture benefits from more triangles, a minimal one from fewer.
If you are after a different kind of graphic filter, this is one of a family of effects here: the threshold tool reduces a picture to stark black and white shapes, the polka dot generator rebuilds it from dots, and the stripe pattern generator makes clean geometric backdrops from scratch.
The whole pipeline - edge detection, triangulation, colour averaging, export - is a creator that runs on your device in the browser's canvas. Your photo is never uploaded, there is no account and no watermark, and the page keeps working offline once it has loaded. The preview you shape is exactly the mesh you download, at full resolution.
Drop the image on the page, or paste it from the clipboard, and the low poly version appears immediately. Drag the Detail slider until the triangle count suits the picture, raise Edge focus to make the mesh trace the subject, press New pattern if you want a different arrangement, then download as PNG, JPG or WebP at full resolution. Free, no signup, no watermark.
Low poly is a style that represents an image with a small number of flat-shaded polygons, almost always triangles. It started as a technical limit in early 3D games and became a deliberate aesthetic: a faceted, gem-like simplification of a photo that keeps its colours and composition while turning every surface into clean geometric planes.
It depends on the subject and the size at which the art will be seen. Portraits usually look right around 500 to 1500 triangles: enough for the eyes and mouth to survive, few enough that the facets stay visible. Landscapes tolerate fewer, and images with fine detail or text need more. The count updates next to the Detail slider as you drag, so watch the picture rather than the number.
The generator detects the edges in your photo - the lines where brightness changes sharply - and edge focus decides how many of the mesh's points sit on those lines rather than spread evenly. High edge focus draws the subject's outline precisely and leaves flat areas as large triangles, which is usually what makes a low poly portrait read well. Low edge focus gives a more uniform, abstract pattern.
The mesh is generated from a fixed seed, so identical settings always rebuild identical art - useful when you need to reproduce a result or make the same style across a set of images. The New pattern button is the deliberate way to get a new variation: it reshuffles the mesh while keeping your detail and edge settings.
Yes. The triangles are stored as geometry and redrawn as vectors at the size of your original photo, so the facet edges are perfectly sharp in the saved file - noticeably better than tools that scale up their on-screen preview. A 4000 pixel photo downloads as a 4000 pixel piece of polygon art.
No. Edge detection, triangulation and colouring all run in your browser, and the download is created on your device. Nothing is transmitted anywhere, and the tool keeps working with the network disconnected once the page is open.
