Every bundle here downloads with more than one file inside, and the most common support question we get is some version of "which one do I open?" The answer depends entirely on what the machine or the printer is about to do with it.
SVG is a set of instructions, PNG is a picture
An SVG does not store pixels. It stores the shapes: this curve starts here, bends this way, closes there. Your machine reads those coordinates and moves a blade along them. Because the file is math rather than a grid of dots, the same file cuts cleanly at two inches or two feet.
A PNG is a fixed grid of pixels. Enlarge it and there is no extra detail to draw with, so the software has to invent it. That is what a soft or stair-stepped edge actually is: a machine guessing where a line was supposed to be.
The practical rule
- Cutting or engraving (Cricut, Silhouette, Glowforge, a vinyl plotter): use the SVG. It is the only format that gives the blade a real path to follow.
- Print-on-demand and sublimation: use the PNG, at the largest size provided, with its transparent background intact. Most print services want a raster file and will rasterize an SVG anyway, usually at a size you did not choose.
- Screen use (a mockup, a listing photo, a social post): PNG is fine, and easier to drop into whatever you are already working in.
- Editing before you cut (splitting a design, recolouring layers, removing an element): open the SVG in Inkscape, Illustrator, Affinity Designer, or Design Space itself. The layers survive.
Why a PNG sometimes "works" on a cutting machine anyway
Design Space and its equivalents will happily accept a PNG and trace it into a cut path for you. It works, in the sense that something comes out the other end. What you lose is precision: the trace approximates the outline it thinks it sees, so fine serifs get rounded, thin strokes close up, and small counters (the hole in an "a") fill in. On a big, chunky shape you may never notice. On a script quote at four inches wide you will.
A few things that are not the file's fault
If a cut goes wrong, check these before assuming the design is broken:
- Blade depth and material setting. Nine out of ten ragged cuts are a setting, not a path.
- Scale. Some detail has a floor. A design with 1mm strokes at its intended size becomes uncuttable at half that.
- Grouping. If a design moves as one block when you want to recolour a single layer, ungroup it first; the layers are there.
If you open a file from the catalog and something looks off, tell us which design and which machine and we will look at the actual file. Support here is a person who has the source art open, not a queue.
