Does a transparent PNG work?

Yes. Transparency is filled with white before tracing, so the background is ignored and only the dark artwork is outlined. A white logo on a transparent background will come out empty, so use a dark version.

Why did some colors disappear?

The tracer only outlines areas darker than mid-gray. Yellow, light blue and pale colors are treated as background. Darken them in any image editor before converting.

Are the outlines closed?

Yes. Each shape is a closed POLYLINE, which laser and CNC software treat as a piece to cut or an area to engrave. Holes, like the middle of an O, get their own closed outline.

What size is the DXF?

It has no units: one pixel of the PNG is one unit, so an 800-pixel-wide PNG is 800 units wide (800 mm if your software assumes millimeters). Scale it after importing.

Can I turn a PNG into a 3D model?

No, the DXF is a flat 2D drawing. In Fusion 360 or another CAD app you can extrude its closed outlines into a 3D part.

What happens to my files?

The PNG is uploaded over HTTPS, traced on our server and deleted automatically within 2 hours, along with the DXF.

How to Convert PNG to DXF

1
Upload the PNG
A transparent or white-background PNG, up to 50 MB (up to 10 files at once).
2
Shapes are outlined
Transparency becomes white, then each dark shape gets one closed outline.
3
Import and size it
Bring the DXF into LightBurn, Fusion 360 or your CAD app and scale it (it has no units).

Why PNG traces cleanly

A PNG straight from a design app has clean, sharp edges, unlike a JPG that has been saved again and again on websites and in chats, so the traced outlines follow the real shape closely. Icons, clipart, silhouettes and logos exported from Canva or a design app usually come out with smooth curves and few stray specks.

Transparent backgrounds

Transparent areas are filled with white before tracing, so the background drops out and only the artwork is outlined. That works for a dark logo on a transparent background. A white or light logo made for dark backgrounds has nothing left to trace once the transparency turns white, and the DXF comes out empty: use the dark version of the logo instead.

What you get in the DXF

Feature	In the DXF
Shapes	One closed POLYLINE around each dark area, and one around each hole in it
Colors	None: every area darker than mid-gray is outlined the same way
Layers	Everything on one layer
Units	No units: one pixel of the PNG is one drawing unit

From DXF to a finished cut

Scale first: a PNG 800 pixels wide arrives 800 units wide, so measure a known length and scale the drawing to its real size.
Choose cut or engrave: closed outlines can be cut out as pieces, or filled to engrave the whole shape.
Thin parts: lines narrower than your laser kerf or CNC bit will not survive. Thicken them in the PNG before tracing.
Colored artwork: light colors such as yellow drop out. Make the parts you want to cut dark before converting.
