How it works
Upload
Drop any photo. A part, a sketch on paper, a reference image. PNG, JPG, or WebP.
Set scale
Drag a line across a known dimension and enter the real-world size, or skip to use the default scale.
Download
AI generates a clean line drawing, then converts to DXF with accurate dimensions.
Why the output is cleaner
Tracing an image is easy. Producing geometry you can actually build from is the hard part, and it is where most converters give up.
Single lines, not doubled
Strokes are thinned to a 1px centerline before tracing, and contour pairs that are really two edges of one stroke get merged. You do not delete half the geometry by hand.
Arcs and circles detected
Geometry that fits a circle, arc or rectangle is exported as a true entity you can dimension and constrain. Everything else is simplified, not left at one point per pixel.
Correct from the first import
Set one known dimension and everything scales to match. Angles and endpoints are snapped, so edges that should meet actually meet and the profile closes.

Frequently asked questions
How conversion works, what happens to your data, and more.
Most trace the boundary of every dark region, so a drawn line arrives as two contours with a hollow sliver between them, and you delete half of them by hand in CAD. Bevell thins every stroke to a one-pixel centreline first and merges contour pairs that turn out to be two edges of the same stroke, so a line comes out as one line.
Both, once you set the scale. Drag across a dimension you already know, type the real measurement, and every curve is scaled to match so the file imports at true size. Shapes that genuinely are circles, arcs or rectangles are exported as those entities, so you can dimension and constrain them. A freeform outline stays a polyline, because that is what it is.
Direct trace when the upload is already a drawing, scan or PDF: every stroke is followed as it was drawn, with nothing redrawn. Outline only for a photo of a real object: the background is removed and the silhouette and its holes are measured. AI redraw for a complex photo or a rough sketch, where an AI redraws it as clean linework first. That last one interprets rather than measures, so it can shift or drop detail; check the preview when accuracy matters.
Photos as PNG, JPG or WebP up to 10 MB, and drawings as PDF or TIFF up to 50 MB, one page at a time. Every conversion returns both a standard DXF and a true-scale SVG, opening in Fusion 360, AutoCAD, SolidWorks, Onshape, FreeCAD, LightBurn and Inkscape. On a drawing you can also have the lettering read as editable CAD text rather than traced.
Converting is free and unlimited with no account needed, because being charged to iterate towards a good result is no good to anyone. Downloading is what costs: three free when you sign up, then £9.99 a month for unlimited downloads. A download covers the job rather than the format, so you can take both the DXF and the SVG, and re-downloading a file you already took is always free. If you subscribe and download nothing, ask within 14 days and you get a full refund. The preview carries a small watermark; the DXF and SVG you download never do.
Your upload and its preview are deleted within 24 hours. If you are signed in, the files you downloaded stay in your history while your account is active. Direct trace and Outline only run entirely on our own servers; AI redraw sends a copy to OpenAI, which does not train on API inputs per their data usage policy. We train nothing ourselves, and the files you download are yours to use commercially with no attribution.
