Raster vs Vector Engraving: Choose the Right Workflow
Decide whether the job needs pixel-based image engraving or vector geometry for line, fill or cut operations before preparing the file.
Use raster engraving when the job is an image rendered as pixels; use vector geometry when the receiving workflow needs selectable lines, filled regions or closed shapes. LightBurn documents images for engraving and vectors for cut, score or engrave operations, but this comparison does not prescribe machine settings or prove a fabrication result.
Start with the operation, not the extension
Raster and vector describe how the artwork is represented and processed. SVG or DXF is a file format choice; it does not by itself decide whether a job is raster engraved, vector engraved, scored or cut.
Choose the row that matches the intended mark, then inspect the geometry or pixels in the receiving application. Keep the source, selected mode and software version with any result you report.
| Intended operation | Representation to prepare | First check before handoff |
|---|---|---|
| Photo, shaded artwork or pixel texture | Raster image for an image-engraving workflow | Pixel dimensions, contrast and image placement |
| A single selectable line or outline | Vector line geometry | Path selection, endpoints and intended line mode |
| A filled region or closed shape | Closed vector path with fill geometry | Closure, winding/overlap and fill behavior |
| A material boundary or profile | Closed vector geometry for a cut workflow | Complete contour, holes and dimensions |
| A mixed job with image and geometry | Separate raster and vector objects/layers | Which object uses which operation and layer |
Make the choice in five checks
Name the intended mark
Write down whether the result is an image tone, a visible line, a filled area or a material boundary. This decision is more precise than choosing SVG or DXF first.
Inspect the source
For raster work, inspect resolution, contrast, transparency and unwanted background. For vector work, inspect paths, closure, holes, overlaps and dimensions.
Assign the receiving operation
In LightBurn, images are used for engraving while vector shapes can be assigned to Line or Fill behavior and used for cut, score or engrave operations. Confirm the selected object and layer.
Keep raster and vector objects separate
A mixed design can contain both representations. Label or isolate them so a pixel image is not mistaken for a cut contour and a vector outline is not treated as a photo.
Verify after import
Reopen the saved file, select the intended objects, and check size, direction, holes and visible operation assignment. Record what was checked instead of inferring machine behavior.
What the LightBurn distinction does and does not answer
LightBurn’s documentation distinguishes images used for engraving from vectors used for cutting, scoring and engraving. Its Line and Fill modes also describe different treatment of vector geometry, including the need for closed shapes when a filled region is intended.
That documentation explains software workflow concepts. It does not supply universal power, speed, interval, material or machine settings, and a successful import is not evidence of a physical fabrication result.
Use a small, observable comparison
For a controlled review, place one raster image and one simple closed vector shape in separate layers, then inspect each object’s selection and assigned operation. A self-made fixture can show the representation difference; it is not LightBurn output or a machine test.
Compare the image object’s pixel/placement properties with the vector object’s path closure, fill and bounds. If the receiving application changes the appearance, preserve both the original and imported copy for diagnosis.
Keep the result evidence-bound
Use the local PNG-to-SVG workflow when you need monochrome vector geometry, then check the resulting paths. Use the LightBurn import guide for a recorded SVG/DXF size and topology check. These checks do not establish a universal fabrication result.
Do not choose power or speed from this page. Capture the actual machine, material, lens, focus, software version and settings in a separate controlled test when that evidence is required.
Sources and verification
The comparison follows LightBurn’s official Images vs Vectors explainer and its Line Mode and Fill Mode references. The page is a method comparison, not a machine/material settings guide. No physical laser test or universal fabrication result is claimed.
