What a cutter actually needs
Cutting and plotting software works from closed vector outlines. It reads the geometry, then applies its own logic: which outline is cut, in which order, with what offset for the blade or beam, and at which size on the mat or bed. An SVG from a tracer supplies the first part only — the outlines. Everything from "offset" onward belongs to the machine's software, which is why no traced file can be called a validated toolpath.
The trace gives you one filled <path> per colour, drawn largest-first. That maps naturally onto layered vinyl (one colour per layer) and onto single-line cuts once the software converts fills to outlines.
Step 1 — trace for cutting, not for looks
- Upload the largest, cleanest version of the design. Transparent-background PNGs are ideal.
- Choose the Cricut / Vinyl preset or Standard; set the colour count to the number of vinyl colours you intend to cut (a one-colour decal: 2, background included).
- Keep Smooth curves on. Cutters follow curves better than staircases, and fewer nodes means fewer tiny direction changes.
- Turn on Remove background so the backdrop does not become a giant rectangle to cut.
- Convert and inspect the preview at full size: no speckles, no broken thin strokes, the palette shows only your intended colours.
Previews are free; iterate until the shape count matches what you will cut. Then unlock the clean SVG.
Step 2 — simplify in the editor
Open the unlocked result in the SVG editor (no extra credit for an unlocked result):
- Delete any leftover background or speckle shapes.
- Merge colours that will be cut from the same material by recolouring them to one fill; that tells you visually which layer they belong to.
- Export the SVG. If you want a smaller file, run it through the optimiser at a moderate precision; aggressive rounding can shift hairline details, so check the result.
Step 3 — hand off to the machine's software
Import the SVG into your cutting software and do the machine-specific work there:
- Size it in the software's units. The SVG carries a
viewBoxin pixels; every program maps that to physical size differently, so set the final dimensions after import. - Convert fills to cut lines (often automatic) and, where needed, release or weld compound paths so holes in letters are treated the way you want.
- Offset, kerf and order are machine decisions: apply them in the software, then cut a small test piece before committing material.
Checks that catch most problems
- Open the SVG in a browser at 400 %: any wobble you see will be cut.
- Count the shapes in the editor's layer list: unexpected extras are speckle; delete them.
- Text: if it came from a small raster, retype it with the Text to SVG tool, which emits letters as clean outlines from bundled fonts, and place it in the editor.
- Thin bridges (the part of a stencil that holds an island in place) must be visibly wider than your blade or beam allows; the tracer will not add bridges for you.
