I STRONGLY recommend always using SVG cut files because they save with more data and are a better quality file. Cricut machine will always work with SVG cut files.
PNG or JPEG – A PNG is just like a clipart image. Clipart images are flattened designs meaning the colors are blended, and you cannot separate each layer by color.
HOW DO I UPLOAD MY SVG FILES?
Uploading SVG files are quite simple – much like opening a document in any other program. It is important to note that you will need to unzip compressed files FIRST.
