Know what converts before you start
The tracer follows the boundary between light and dark, which means the source image decides most of the result. High-contrast artwork converts well. Soft gradients do not.
Drop in a PNG, JPG, or scanned sketch and download clean DXF R12 vector paths. The trace runs instantly in your browser, gets sized in real units, and is ready for your laser, plasma table, waterjet, or CNC router.
Runs in your browser. Images never upload. No account. First 3 exports free.
Most image-to-vector converters are made for illustrators, and it shows: they hand you a polygon with 40,000 vertices and no idea what a kerf is. This one is built around what a cutting machine can actually do.
Circles arrive in your CAM software as DXF bulge arcs instead of hundred-chord polygons, so the machine holds feed rate through every curve.
Strips too narrow to survive the cut are grown to your limit. Anything with a solid core is left exactly as drawn. Squares stay squares.
Slots narrower than your cutter get widened so detail comes out as detail, instead of two walls merging into a single cut.
The middle of an O drops free the moment the surrounding cut completes. The tracer outlines those islands in red so you can bridge or accept them before cutting.
Push outer edges out or shrink holes in. Positive always means more material, and outer and inner edges are controlled separately.
Pierce count and total cut length update live as you adjust. Multiply by your feed rate and price the job before touching a sheet.
PNG, JPG, GIF, WebP, or BMP, or paste straight from the clipboard. Transparent logos trace from their alpha channel automatically.
Press Auto and the right split is found for you. The Threshold view shows exactly what was selected before you trust any paths.
Denoise, simplify, round corners, enforce your minimum widths. Fix anything by hand with the Keep and Erase brushes.
Type the finished width in inches or millimetres and download a DXF R12 file that any CAD or CAM package opens.
The tracer is a real geometry pipeline, not a filter. Each stage exists because of something a cutting machine needs from the file.
The image becomes a two-tone mask of part and background, split at a brightness you control or picked automatically from the image's own histogram.
A marching-squares tracer follows every edge in the mask at sub-pixel precision, producing closed loops with holes and outlines told apart by winding.
Specks are dropped, paths simplified, corners optionally rounded, and minimum material and cut widths enforced on the shape itself, not painted over.
Runs of points that lie on a circle collapse into true arcs and straight runs merge into single lines, cutting thousands of vertices down to a handful.
Closed polylines with bulge arcs, outer boundaries counter-clockwise and holes clockwise, which is the layout CAD and CAM software expects.
The tracer follows the boundary between light and dark, which means the source image decides most of the result. High-contrast artwork converts well. Soft gradients do not.
Tracing and previewing are always unlimited. Only downloads count. No subscription, no account.

No. Tracing happens entirely in your browser on your own processor, which is why it responds instantly as you move a slider. Only the finished outline coordinates and your chosen file name are sent, and only at the moment you export a file.
PNG, JPG, GIF, WebP, and BMP, anything your browser can display. A transparent PNG is the best input of all: the tracer uses its alpha channel directly and skips the threshold problem entirely.
DXF R12, with closed polylines on layer 0 and arcs stored as bulges. R12 is deliberately the oldest revision, because every CAD and CAM package reads it without argument.
Anything that reads DXF: Fusion 360, LightBurn, SheetCam, AutoCAD, SolidWorks, Inkscape, QCAD, VCarve, and the controllers built into most cutting tables and routers. Outer boundaries are wound counter-clockwise and holes clockwise, which is how CAM software tells them apart.
Only if it has genuine hard contrast. Continuous-tone photographs have no single edge to follow. Reduce the photo to a two-tone stencil first, then trace that. The examples page shows the difference.
The first three DXF exports are free, and tracing and previewing are always unlimited. After that, watch a short video ad for one more export, or pay $14.99 once for unlimited exports forever, with no subscription. Details on pricing.
