PNG to SVG for Cricut: how to get clean cut lines

Updated October 25, 2026 · Rasterklar

Short answer

Trace the PNG into an SVG with one group of closed paths per colour, no background rectangle and holes kept as holes, then upload the SVG: Design Space imports SVG and DXF as vector images already separated into layers, while a PNG arrives as one flat image you erase and trace by hand (Cricut, read 2026-10-24). Rasterklar does that trace in the browser, free for 2 images a day.

Design Space treats a PNG or JPG as a single flat layer you have to clean up by hand, and an SVG as vector shapes it separates into layers on upload. A clean SVG is the difference between one click and twenty minutes of erasing. Here is what “clean” means for a cutter and how to get it from a PNG.

Mode
Lower keeps sharp corners; higher rounds them.
Higher merges curves: fewer nodes, softer outline.
Shapes smaller than this many pixels are dropped.

Why a traced SVG beats “Upload → Complex” for cutting

When you upload a PNG, Design Space asks you to erase the background and then traces the remaining pixels itself into one cut layer. Every colour of the design ends up as one shape, the edges follow the pixels, and the file has to be cleaned each time you reuse it.

A traced SVG arrives already separated: each colour of the design is its own layer, each shape is a smooth closed path, and the background is simply absent. You can hide, re-colour or weld layers, and the same file cuts the same way next time.

What makes cut lines clean

Four things decide whether the blade does what you expect:

  • No background box. A white rectangle around the design becomes a cut around the whole sheet. In colour mode the tracer leaves out the colour that runs along the image border; in black and white mode it only traces the dark side.
  • Holes kept. The inside of an “O” or the centre of a ring must be a hole, not a filled shape on top of another. The SVG uses the even-odd fill rule, which Design Space follows: a contour inside a contour is a hole.
  • Few, smooth nodes. Hundreds of tiny segments make the blade stutter. Smoothing merges curves; despeckle removes the specks that would otherwise become hundreds of micro-cuts.
  • The right size. The SVG states its width and height in millimetres, computed from the DPI, so it imports at that size instead of a guess.

Settings that work for vinyl and iron-on

Start with the “Cricut / Silhouette cut file” preset (black and white, corner threshold 1, smoothing 0.2, despeckle 4, 300 DPI), then adjust:

  • Thin script fonts losing their hairlines: lower despeckle to 1 or 2 and lower the corner threshold a little.
  • Wobbly edges on a low-resolution PNG: raise smoothing to 0.5 or more.
  • A multi-colour sticker: switch to colour mode with as many colours as the design has inks, plus one for the background.
  • White details on a dark design: black and white mode with “trace the light side” checked.

From PNG to a Cricut cut in five steps

  1. Open the tracer. Drop your PNG on the tracer and choose the Cricut / Silhouette preset.
  2. Check the preview. Look at the cutting-mat preview: every shape you want to cut should be there, with holes where holes belong, and nothing around the design.
  3. Set the size. Pick the DPI the PNG was made for; the preview shows the size in millimetres and inches.
  4. Download the SVG. Download the SVG (free up to the reduced size, full resolution with a pass).
  5. Upload to Design Space. In Design Space choose Upload, pick the SVG, and it arrives as one layer per colour, ready to cut.

Questions

Does Design Space keep the size of the SVG?

The SVG declares its width and height in millimetres. Check the size shown in Design Space against the size in our preview after the first upload; if your version of Design Space rescales, resize once to the millimetres shown in our preview.

Can I use it for Silhouette Studio?

Yes. Opening an SVG needs Silhouette Studio Designer Edition or higher (Silhouette America); the free edition opens DXF instead (Silhouette School), so with the free edition use the DXF, which needs a pass. The SVG vs DXF guide compares the two.

Why is the free SVG smaller than my PNG?

The free tier traces at up to 480 px on the longest side, which is enough for a sticker but loses fine detail on a large design. A pass traces at up to 3000 px.
