What This Guide Covers

This tutorial explains:

  • Which file formats are supported in LightBurn
  • The difference between image and vector file types
  • How to import files into LightBurn
  • The correct way to open projects
  • Common import issues and troubleshooting tips

Quick Answer

LightBurn supports multiple project, vector, image, and machine file formats including .lbrn, .svg, .dxf, .ai, .pdf, .png, .jpg, .bmp, .gcode, and more. You can import files either by opening them directly in LightBurn or by using the Import function inside an existing project.

Why This Process Matters

Using the correct file format is essential for successful laser engraving and cutting. Different file types contain different types of information:

  • Vector files are typically used for cutting paths and scalable graphics
  • Image files are commonly used for photo engraving
  • Project files preserve LightBurn workspace settings and layers
  • Machine files may contain motion data for laser systems

Importing files incorrectly can lead to:

  • Missing artwork
  • Incorrect scaling
  • Lost layer settings
  • Broken vectors
  • Unsupported file errors

Understanding supported LightBurn file formats helps prevent workflow problems and improves engraving accuracy.

Before You Start

Before importing files into LightBurn, make sure:

  • LightBurn is properly installed
  • Your laser engraver is connected correctly
  • The file you want to import is supported
  • The design file is saved locally on your computer

If you are unsure whether your file type is compatible, check the supported formats list below.

Requirements

You will need:

  • A computer running LightBurn
  • Supported design or image files
  • A compatible laser engraver
  • Basic familiarity with the LightBurn interface

Follow official machine specifications or instructions.

Precautions

Before importing files into LightBurn, keep these precautions in mind:

  • Do not modify original project files unless necessary
  • Verify the file type before importing
  • Large image files may slow down software performance
  • AI-generated files may not always import correctly
  • Some imported GCode files may not preserve speed and power settings

Vector files are commonly used for cutting paths, logos, outlines, and scalable graphics.

Step-by-Step Tutorial

Step 1: Open Directly in LightBurn

Action

Open the file directly inside LightBurn.

This method is commonly used when starting a new project from an existing file.

Expected Result

The selected file opens as a new LightBurn project or workspace.

Important Notes

  • Opening a file directly may replace the currently loaded project
  • Save your existing work before opening another file
  • Supported project, image, and vector files can all be opened directly in LightBurn

Step 2: Import Files into an Existing Project

Action

Use the Import function inside LightBurn to add artwork into the current project.

Expected Result

The imported design appears on the LightBurn workspace while keeping your existing project open.

Important Notes

  • Importing is useful for combining multiple designs into one workspace
  • Imported artwork can usually be resized, moved, or edited after loading
  • LightBurn supports importing both image and vector formats

Understanding Image vs Vector Files

Many beginners are unsure whether they should use image files or vector files in LightBurn.

Image Files

Image files are made from pixels. These are best for:

  • Photographs
  • Shaded artwork
  • Detailed raster engraving
  • Grayscale engraving

Common formats include:

  • PNG
  • JPG
  • BMP
  • GIF
  • TIFF
  • WEBP

Vector Files

Vector files use mathematical paths instead of pixels. These are best for:

  • Cutting
  • Logos
  • Text outlines
  • Precision engraving
  • Scalable graphics

Common formats include:

  • SVG
  • DXF
  • AI
  • PDF

Vector files generally provide cleaner cutting results because paths remain sharp regardless of scaling.

Common Problems and Solutions

Problem Possible Cause Solution
File will not import Unsupported file type Verify the file extension is supported
Imported artwork is missing Unsupported fonts or broken vectors Convert text to paths before exporting
Design appears too large or too small Scaling mismatch Resize the artwork inside LightBurn
Imported GCode loses settings GCode geometry only imported Reconfigure speed and power settings manually
Blank import result Corrupted or incompatible file Re-export the file from the original software
Current project disappears after opening a file Used Open instead of Import Use Import when adding artwork to an existing project
LightBurn says “Nothing Imported” Unsupported embedded elements Convert artwork to outlines or paths first

Tips for Better Results

Use SVG for Most Vector Work

SVG files are widely compatible and usually preserve vectors accurately across different design programs.

Save Original Design Files

Always keep a backup copy of your original artwork before editing or importing.

Check Artwork Before Engraving

After importing:

  • Verify dimensions
  • Check alignment
  • Confirm layers
  • Preview cut paths

Avoid Unsupported Fonts

Embedded fonts may not import correctly in some situations. Converting text to outlines can improve compatibility.

Use Import Instead of Open When Combining Designs

If you want to add artwork into an existing project, Import is usually the better choice.

Be Careful with AI-Generated Files

AI-generated SVG or vector files may contain invalid paths or unsupported structures that can cause import issues.

LightBurn supports project, vector, image, and machine formats including .lbrn, .svg, .dxf, .ai, .pdf, .png, .jpg, .bmp, .gcode, and more.

Can LightBurn import SVG files?

Yes. SVG is one of the most commonly used vector formats in LightBurn.

What is the difference between Open and Import in LightBurn?

Open loads a file as a new project, while Import adds artwork into the currently open project.

Can I import JPG and PNG images into LightBurn?

Yes. LightBurn supports importing JPG, PNG, BMP, GIF, TIFF, TGA, and WEBP image files.

Why are my fonts missing after importing?

Some embedded fonts are not supported during import. Converting text to outlines before exporting may help.
