Build a compact cutting layout.

Import closed SVG outlines, describe your material, and watch SVGnest improve a local best-so-far arrangement until you stop it.

Prepare closed vector outlines first. Convert text and strokes to paths and remove duplicate or overlapping geometry. The tool rejects active SVG content and applies bounded geometry limits before starting workers.

Step 1

Import vector parts

Choose or drop one SVG. Nothing is uploaded.

SVG only · 10 MiB maximum · 5,000 elements · 1,000 contours · 100,000 polygon points

Choose an SVG to begin.

Step 2

Choose material

SVG units

Material width SVG units Material height SVG units

Physical units will be shown only when the SVG provides a consistent width, height, and viewBox mapping.

Sheet candidates

Select the editable rectangle or a valid imported outline.

Geometry check

Parts and contours

Parts: 0
Contours: 0
Valid: 0
Excluded: 0
Polygon points: 0
Source elements: 0

Parts are top-level valid contours after the selected sheet is excluded. Nested contours may represent holes.

Step 3

Set spacing and rotation

Part spacing SVG units Minimum edge-to-edge separation. Rotation choices Four choices considers 0°, 90°, 180°, and 270°.

Advanced search settings

Curve tolerance SVG units Smaller values retain more curve detail and cost more work. Population Candidates evaluated in each search generation. Mutation rate % Variation introduced between generations.

Allow part-in-part placement Explore concave areas

Step 4

Search for a layout

The search has no fixed finish line. Stop when the best result suits the job. Net part utilization subtracts nested holes from placed part area, divides by the selected sheet-outline area, and does not count spacing as part material.

Best-so-far nesting, without a server.

SVGnest uses geometric no-fit polygons and a genetic search. Each evaluation may improve the result; elapsed time and batch progress describe activity, not a promised completion percentage.

Your artwork stays local

The browser reads and sanitizes the SVG. No artwork is uploaded.

Bounded before work begins

Element, contour, point, part, and coordinate budgets protect the browser and worker pool.
