How to convert a PNG to DXF
- 1
Upload your image
Drop a PNG (transparent ones too), JPG or WebP. A black logo on a white background traces best.
- 2
Pick a mode
Outline gives closed contours around every filled shape, holes included. Centerline gives one line down the middle of thin strokes.
- 3
Clean it up
Move the threshold (or leave it on auto), remove small specks, and simplify until the green lines match your shape.

Set the size and download
Type the width in mm or inches; the height follows. Download a DXF for CAD and laser software, or an SVG.
Tips for laser cutting and CNC
- Use Outline mode for cutting. Every outline is a closed polyline, so laser and CNC software can cut or pocket it without joining lines first.
- Holes stay holes. The inside of an O, A or D is its own closed path inside the outer one, so it drops out when you cut.
- Set the real size here. A PNG has no physical size, so type the width you want to cut; the DXF is written in that unit and tells your CAD program which unit it uses.
- Kerf is up to your cutter. The DXF follows the edge of the shape exactly; add the kerf or tool offset in your laser or CAM software.
- Small specks and dust in a scan become tiny paths that waste cutting time. Raise "Remove specks" until they are gone.
- For a photo or a soft image, move the threshold slider until the shape you want is solid. Photos with gradients rarely trace well; a high-contrast version does.

The same logo can become a 3D print: extrude it into an STL for free, or let our AI build a full 3D model from a photo and paint it. The AI tools use credits; this converter does not.
Frequently Asked Questions
Upload the PNG on this page, choose Outline mode, check the green lines in the preview, set the width in mm or inches and press Download DXF. It is free, needs no account, and the image is traced in your browser, so it is not uploaded to our server.
The file is a DXF R12 (AC1009) with every path as a POLYLINE, the oldest and most widely read DXF form, which AutoCAD, LibreCAD, Fusion 360, Inkscape, LightBurn and most CNC and laser programs open. The drawing sits at the origin with Y pointing up, so it is not upside down.
Outline traces the edges of filled shapes as closed loops, with holes, which is what you want for cutting a shape out. Centerline draws a single line down the middle of each stroke, which suits engraving, pen plotters and thin line art, but its lines are open, so it is not for cutting out shapes.
Choose Millimetres or Inches and type the width you want; the height follows the drawing’s proportions, or type the height instead. The size is the traced drawing itself, not the empty space around it. The DXF header records the unit ($INSUNITS) so CAD programs import it at that size.
Low-resolution or blurry images give jagged edges, and noise or JPG artefacts give extra specks. Raise "Remove specks" to drop small blobs, raise "Simplify" or "Smooth curves" for cleaner lines, and move the threshold. A larger, high-contrast image gives the best result.
Yes. When the image has transparency the tool traces by it automatically, so a logo of any colour on a transparent background is traced by its shape. You can switch to "Dark pixels" to trace by brightness instead.
