Guide of What File Format Does a Laser Cutter Use

Laser cutters are now synonymous with precision and intricate design, but there’s a key element behind every amazing laser cut piece the file type. In this comprehensive guide, we reveal the importance of laser cutter file types, exploring how choosing the right format can improve efficiency, accuracy and overall project success.

In the guide, we reveal the importance of file types for laser cutters and explore how to choose the right guide.

What File Format Does a Laser Cutter

Laser cutting machine is a kind of precision processing equipment widely used in the manufacturing industry. It uses high-energy density laser beams to cut, engrave, punch and other processing materials. To use a laser cutting machine for processing, it is necessary to first convert the designed graphics into a file format that can be recognized by the laser cutting machine.


Laser Cutter File Type

Before delving into the world of laser cutter file types, it is essential to master the basics. Common file formats include DXF (Drawing Interchange Format) and SVG (Scalable Vector Graphics). DXF is widely recognized in the engineering and manufacturing industries, while SVG is a web-friendly format that is suitable for a variety of applications.

The file formats commonly used in laser cutting machines are as follows:

  • DXF (AutoCAD Drawing Exchange Format): DXF is a vector graphics file format developed by Autodesk, which is widely used in CAD software. DXF files contain geometric information of graphics, including line segments, arcs, polygons, etc. Laser cutting machines can read graphics information by importing DXF files and perform cutting operations based on this information.
  • G-code: G-code is a numerical control programming language used to control the movement and operation of equipment such as machine tools and robots. In a laser cutting machine, the G-code file contains instructions such as cutting path, cutting speed, power adjustment, etc. By parsing and executing these instructions, the laser cutting machine can perform cutting operations according to a predetermined path.
  • AI (Adobe Illustrator): AI is a vector graphics editing software developed by Adobe, which is often used to design and draw graphics. AI files contain geometric information and color information of the graphics. Laser cutters can usually read AI files and import the graphics into cutting software for processing and programming.
  • PLT (HPGL Plotter Language): PLT is a plotter file format developed by HP, which is often used to draw engineering drawings. PLT files contain information such as lines, arcs, and text of graphics. Laser cutters can usually read PLT files and convert them into G code files for cutting operations.
  • BMP (Bitmap): BMP is a bitmap graphics file format developed by Microsoft, commonly used to store photos and images. BMP files contain pixel information of graphics. Laser cutters can convert BMP files to vector graphics files through software, and then cut operations.

In addition to the commonly used file formats mentioned above, some laser cutting machines also support files in other formats, such as SVG, IGES, DWG, etc. For specific supported file formats, please refer to the user manual of the laser cutting machine or consult the manufacturer.

Select laser cutting machine file format

  • Graphic type: If the graphic is a vector graphic, you can use DXF, AI, PLT and other formats; if the graphic is a bitmap graphic, you can use BMP format.
  • Compatibility of laser cutting machine: You should choose a file format supported by the laser cutting machine to avoid problems such as being unable to read or process.
  • Graphic accuracy: If the graphics require high accuracy, you should choose a file format that can save higher accuracy, such as DXF, AI, etc.
  • Dosya boyutu: You should try to avoid using files that are too large to avoid problems such as slow software operation or freezing.

Compatibility issues

It is crucial to choose a laser cut file format that is compatible with your specific machine. Incompatibilities can lead to errors, loss of accuracy, and in the worst case, project failure. Consult your laser cutter’s manual or

Vector vs. Raster: Choosing the Right Path

Laser cutting mainly relies on vector graphics to ensure its accuracy. Unlike raster images, vector graphics maintain clarity and quality regardless of size. Knowing

Choose software for best performance

Different laser cutters may have different software preferences. Some may handle DXF files seamlessly, while others may prefer SVG. Taking the time to understand your laser cutter’s preferred file types and master the associated software can significantly improve the efficiency of your workflow.


Mastering the laser cutting file type is an indispensable skill for anyone entering the field of laser cutting. From understanding compatibility to choosing between vector graphics and raster graphics, every decision contributes to the overall success of your project. Stay informed, stay precise, and let your laser cutting file choices take your designs to new heights.

Explore our in depth guide to laser cutter files to ensure your next project is not only superior to others, but also top of the pack in terms of efficiency and precision. Your journey to mastering laser cutting starts with the right file type choose wisely and create wonderful.


If I only have a picture in BMP format, can I cut it with a laser cutter?

Yes. You can use software to convert the BMP file to a vector graphics file such as DXF or AI, and then perform the cutting operation.

I use AutoCAD software, can I import the DWG file directly into the laser cutter?

It depends on the compatibility of the laser cutter. Some laser cutters can read DWG files directly, while others need to convert DWG files to DXF files before reading.

Where can I find free laser cutter software?

There are many free laser cutter software on the Internet, you can search for “free laser cutter software” to download.
