# What is an SVG file, and why does your machine want one?

Updated 2026-10-29 · 7 min read · Basics

An SVG is a set of instructions for drawing shapes, "start here, curve to there, close the path", rather than a grid of coloured dots. That difference is the entire reason cutting machines want one: a blade follows a path, and a path is exactly what an SVG contains.

## Vector versus raster, and why it matters at the blade

A PNG or JPEG is a grid of pixels. Scale it up and the grid stretches, producing soft or blocky edges. An SVG stores geometry, so it is recomputed at whatever size you ask for and stays exact, a 2-inch star and a 20-inch star are the same file.

A cutting machine needs a path to follow. Given a PNG it must guess where the edges are, which is what "auto-trace" does, and guessing produces thousands of unnecessary nodes that make the blade stutter.

## How to spot a badly-made cut file

Zoom in on a curve. A well-drawn vector has a handful of smooth control points; a traced file has a dense scatter of them, and the curve looks faintly polygonal. That density is what makes a cut ragged on vinyl and torn on cardstock.

Then check whether the shapes are actually closed. An open path has no inside, so the machine cannot decide what to cut away and will often skip it entirely.

## Strokes, fills and the most common mistake

Machines cut the boundary of filled shapes. A stroke, an outline drawn along a path, is a rendering instruction with no area, and most machine software ignores it or cuts down its centre unpredictably.

If you want a thin outline to cut, it must be a closed shape with a fill: an offset, not a stroke. This one distinction explains most "it imported but nothing cut" reports.

## Which file formats work with Cricut machines?

SVG is the most useful format for cutting with a Cricut. Cricut Design Space uploads SVG and DXF as cut-ready vector images, and JPG, PNG, GIF and BMP as basic images that you clean up during upload or use for Print Then Cut. Design Space is the program that sends the cut, so whatever you design elsewhere ends up in one of these formats.

Pick the format by the job, not by habit: vector for anything the blade follows, PNG for anything that gets printed.

Design file formats for Cricut projects

| Format | What it stores | In Cricut Design Space | Best for |
| --- | --- | --- | --- |
| SVG | Vector paths, fill colors and groups | Uploads as a cut image; different fill colors arrive as separate layers | Vinyl, iron-on, cardstock and layered designs |
| DXF | Vector geometry without color | Uploads as a cut image; colors are not carried over | Silhouette Studio Basic, laser and CNC software |
| PNG | Pixels with a transparent background | Uploads as a basic image; cut around the edge or print with Print Then Cut | Stickers, sublimation and printable artwork |
| JPG | Pixels on a solid background | Uploads as a basic image; remove the background during upload | Photos and printed artwork |
| PDF | A fixed page at physical size | Not one of the upload formats listed above; send SVG or PNG to Design Space | Printing templates and patterns at true size |

## How to create a layered SVG design

A layered SVG is several cut pieces stacked on top of each other, usually one per material color: a base shape, a middle layer and the fine detail on top. Each layer is its own closed, filled shape, and each layer uses a different fill color so cutting software can tell them apart.

Build it from the bottom up. Draw or import the base shape, then add each upper layer on top, keeping every piece whole rather than cutting holes into the layer below. A contour offset of the finished artwork makes a quick backing layer that frames everything above it.

Before exporting, check every layer at final size: thin strokes and tiny gaps that look fine on screen become pieces too small to weed. In CricutCraft Studio the Layers panel shows each piece separately; export SVG, and Design Space places each fill color on its own layer and its own mat. Cut, weed, then stack the layers from the base up.

## Questions

### What file formats are best for Cricut machines?

SVG for anything you cut, because it gives Design Space real vector paths and keeps layers separated by color. Use DXF when the software you are using cannot open SVG, and PNG for printed artwork such as stickers and sublimation. JPG works for photos but has no transparency.

### How do I create layered SVG designs?

Make each layer a separate closed, filled shape with its own color, stack them from the base up without cutting holes into the layers below, and add an offset if you want a backing layer. Export SVG; Design Space puts each color on its own layer so you can cut, weed and stack them.

### Can I cut a PNG?

Only by tracing it into a vector first, and the result is as good as the trace. A real SVG always cuts better.

### Why does my SVG import at the wrong size?

It had no physical units, so the importer fell back to pixels. Export at final physical size in inches.

### What is the difference between SVG and DXF?

Both are vector. SVG carries colour and layers; DXF carries geometry only, but opens in software whose SVG import is paywalled, notably Silhouette Studio Basic.
