SVG and DXF are the two file formats we're asked about most. Both are vector formats and both work for laser cutting. The right choice usually depends on the software you design in.
In short
- SVG is common in graphic design software such as Adobe Illustrator, Affinity Designer and Inkscape. It is a good choice for signage, lettering, logos and decorative work.
- DXF is common in CAD software such as AutoCAD and Fusion. It is a good choice for technical parts drawn to precise dimensions.
- Either format is fine, as long as the file is at 1:1 scale in millimetres with clean, closed paths.
SVG (Scalable Vector Graphics)
SVG files store shapes, lines and colours. They are easy to create in design software and keep colours, which is useful for separating cut lines from engraving.
Points to check:
- Units and scale can change when SVG files are exported. Check that your design measures correctly at 1:1 scale in millimetres.
- Convert text to outlines before exporting.
- Avoid embedded raster images unless they are meant to be engraved.
DXF (Drawing Exchange Format)
DXF files come from engineering and CAD software and are well suited to precise geometry. They can hold layers, which can be used to separate cutting and engraving.
Points to check:
- Confirm the drawing units are millimetres.
- Remove dimensions, title blocks, notes and construction lines, or put them on a separate layer that is clearly labelled not to cut.
- Curves are sometimes exported as many short segments. This is usually fine, but very complex exports can be slow to process.
What about PDF and AI?
We also accept PDF and Adobe Illustrator (AI) files, as long as the artwork inside is vector, not a flattened image. If you're exporting a PDF, make sure "preserve editing" or vector output is enabled.

Send your file with your quote request. If we spot anything that needs fixing, we'll let you know before production. See also: how to prepare files for laser cutting.
