SVG Files
An SVG (Scalable Vector Graphic) file is an XML-based vector image format used primarily for web graphics, logos, and icons. Unlike raster formats (JPG/PNG), SVGs are mathematically defined, allowing them to scale to any size without losing quality or becoming pixelated. They are widely supported by browsers and can be edited in text editors.
That is why SVG is the most common file formats used for laser cutting. In fact, most modern laser cutting machines and their associated software (like LightBurn, xTool Creative Space, and Glowforge) can directly open or import SVG. SVGs are preferred because they store vector data, allowing lasers to follow precise lines and curves for cutting and engraving.
An XCS file is a proprietary project file for xTool Creative Space (XCS) software, used to operate xTool laser machines. They save designs, vector/bitmap data, and specific laser processing settings (speed, power). They can be opened in XCS, exported as SVGs for other software, or converted from older formats.
If you import the SVG file into xTool Creative Space, you can save the project and that will make an XCS file that includes the SVG and all of the settings for that run. We currently have both xTool S1 and PS2 machines so our design files are designed and tested in either of those formats.
