Scan to CAD
Scan to CAD, free and online. Convert Scan to DXF and get DXF geometry in real millimetres. Made for scans: paper texture cleaned away. Runs in your browser: nothing uploaded, no sign-up.
Works with: LightBurn · Fusion 360 · AutoCAD · GRBL · Mach3
Drop several files at once to convert the whole folder in one pass. Got a different format? A PNG, JPG, HEIC, PDF, SVG or DXF still comes out as DXF.
× removes a colour and its shapes; click a swatch to change it. Every format follows.

Batch
Every file is traced on its own at its own resolution, with the settings in the panel. A file converted here comes out identical to the same file converted by itself.

Trace settings
Full-colour trace for print and web.
Fine-tune
Raise it to clear dust, grain and stray dots; 0 keeps every mark.
Untick for pixel art: the outline then follows every pixel edge.
With Remove background: how close a colour must be to the background to go with it.
Machine output
Height follows the source aspect ratio.
Laser and Router follow the traced outlines. Engrave photo burns the picture itself, line by line, for photos and portraits.
Heat transfer vinyl is pressed face down, so it has to be cut mirrored. The second box is the overcut in millimetres: a drag knife starts each shape pointing the wrong way, and running past the start covers that stretch properly so the piece weeds out clean.
Beam or bit width. Left at zero the tool runs down the centre of the line, so a part finishes one tool width undersize. Set it and the path is offset by half, with holes offset the opposite way.
Holes before the part that holds them, so nothing comes loose while there is still cutting to do. Also shortens the travel between cuts.
See it on your product
Put this artwork on a 3D mug, tumbler, sign, phone case or canvas, turn it all the way round, or drop it onto a photograph of your own blank. The preview page has the product picker, the colours and the placement controls.
Open the preview and renderHow it works
Upload your artwork
Mono mode is preset, a single cut outline is what a machine wants, not colour layers.
Set your real size
Choose millimetres or inches and the finished width. The file carries physical units, not pixels.
Check the preview, then cut
Inspect the toolpath before you download. Cuts draw solid, rapids dashed.
Scan to DXF converter: free and online
Convert scan to DXF in your browser: drop in a Scan file and download the DXF. The file is converted on your own device and never uploaded, so this scan to dxf converter is safe for private and confidential files.
DXF is the drawing exchange format of CAD, laser and CNC software, from AutoCAD to LightBurn.
The paths come out at the real size you set, in millimetres or inches, ready for a laser, a CNC router, a vinyl cutter or a plotter.
Other conversions to DXF: Sketch to DXF, Floor plan to DXF, Blueprint to DXF, Image to DXF, PNG to DXF, JPG to DXF.

Why it matters
Correct units, stated in the file
DXF exports write $INSUNITS. Without it a part imports at 25.4x the intended size, which is the single most common cause of a ruined first cut.
Y axis the right way up
SVG puts +Y down the screen; CAD and CAM put it up. We flip it. Exporting without that correction gives a part mirrored about the X axis, it cuts, but backwards.
Closed contours
A cutter following an open outline leaves the part attached. Outlines are closed, and anything that is not is flagged before you download.
Conservative G-code
The tool is disengaged before every reposition, retracted before every rapid, and the program always ends tool-off and clear.
Is Scan to DXF worth paying for?
A DXF is the file a shop actually runs. Walk through the artwork requirements a laser cutter, a CNC shop or a sign maker publishes and the same request appears: send something a machine can follow. What turns up instead is a screenshot or a logo pulled off a website at 600 pixels, and somebody redraws it by hand — twenty-five to forty minutes — or sends it to an art service at $25 to $60 a file.
The conversion here is free and unlimited and stays that way. The paid plan is what unlocks the machine formats, which are never watermarked at any tier because a mark in a cut file is extra cut paths a machine would run.
Questions
How do I convert Scan to DXF?
Drop your Scan file on this page, check the preview, and press Download. The DXF is made in a few seconds, with no sign-up.
Is my Scan file uploaded anywhere?
No. The scan to dxf conversion runs in your browser, on your own device. The file never leaves it.
What units does the file use?
Whichever you pick, millimetres or inches, and the choice is written into the file header so the receiving software does not have to guess.
Will this work with my laser?
DXF is written as R2000 by default, which LightBurn, Fusion, AutoCAD and current CAM packages all read. There is an R12 option for older controllers that predate LWPOLYLINE.
Can I trust the G-code?
Preview the toolpath first, and dry-run any new program above the material. The generated code assumes you have set your own work origin, and it homes nothing.
