SVG or DXF – which format to choose?

Both formats store vectors, but they differ in the scope of information and use cases.

Technical differences

DXF is an ASCII file of larger size that stores pure geometry without colours and fills. SVG is written in XML, is lighter and supports colours, gradients, text and layers. In practice this means that SVG is better suited for preview in browsers and for artistic designs, while DXF guarantees the highest precision and is the industry standard.

Which format for your machine?

For Glowforge machines SVG is recommended because the manufacturer’s app uses colours to separate operations. xTool devices work with both SVG (Creative Space) and DXF (LightBurn), so the choice depends on your software. Cheaper diode lasers from Ortur/Sculpfun handle DXF better, and industrial CO₂ machines with Ruida controllers practically require DXF.

Summary

If you are just starting your laser adventure and use simple apps, SVG will be easier to handle and will allow you to prepare your design faster. However, when you need absolute precision and work in a CAD environment, choose DXF. Remember that both formats can be converted between each other – for example in Inkscape or LightBurn. Ultimately the choice should depend on your machine and preferences, because the cutting quality remains the same.
