Download DXF or DWG
Take either format and open the file in your CAD, CAM or laser software.
About formats
IMG is not a file format, it is the shorthand everybody types, and that is worth knowing before you convert one. In practice an "img" is whatever the camera or the phone wrote: most cameras and Android phones name their files IMG_1234.JPG, iPhones write IMG_1234.HEIC, and on the web the word comes from the HTML img tag, which will happily point at a JPG, a PNG, a WebP or an SVG. There is also a genuine .img extension, but it is a raw disk image rather than a picture, and nobody searching for a CAD conversion means that one. So the honest answer is that the file behind the word is almost always a plain raster image: a grid of pixels holding colour values, with no notion of a line, an arc or a contour. Converting it to CAD means tracing the boundaries between light and dark into vector paths, and the extension it happens to carry changes nothing about how well that works. What does change it is the picture itself. Flat, high contrast artwork with clean outlines traces sharply; a busy photo full of shadows and background clutter gives the tracer no single edge to follow.
Frequently asked questions
Why convert an IMG to CAD?
CAD software works in lines, arcs and polylines; an image only holds colour. Converting your IMG into a CAD file turns the shapes in the picture into editable vector geometry, which is what you need before you can dimension it, edit it or send it to be cut.
What software opens these files?
Between the two formats, effectively everything. AutoCAD, Fusion, SolidWorks, FreeCAD, LibreCAD, BricsCAD, DraftSight, Onshape, Rhino and every mainstream CAM and laser package open one or both. Pick DWG if you work in AutoCAD, DXF if the file is going anywhere else.
Does the converter trace the image?
Yes. It finds the edges in your IMG and traces them into closed vector contours, then writes those as DXF or DWG polylines. Because it traces pixels, the output is an outline with no real dimensions or scale, which is perfect for flat cutting but is not a measured engineering drawing.
Is IMG to CAD conversion free?
Yes, and there is no watermark. The conversion runs entirely in your browser, so your file is never uploaded; a free account is needed only to download the finished file.
Should I download the DXF or the DWG?
Take the DWG if you are going to keep editing in AutoCAD, since it is AutoCAD's own format and stays smaller as the drawing grows. Take the DXF for everything else, especially if the file is going to a laser, plasma, waterjet or CNC shop, because DXF is plain text and read by more software than any other CAD format. If you are not sure who is opening it, send DXF. Both come from the same conversion here, so you can take one, try it, and come back for the other.
What IMG files work best?
High contrast images with clear outlines give the best DXF or DWG: logos, stencils, technical sketches, floor plans and simple shapes. Busy photos with shadows and gradients trace poorly because there is no clean edge to follow.
Can I use the file for laser cutting or CNC?
Yes. The traced polylines drop straight into laser, plasma, waterjet and CNC routing software as cut paths. Set an output width in millimetres before you download so the part comes in at real size.
I have a different image, not an IMG. Can I still use this?
Yes. The converter accepts any common image, including PNG, JPG, WebP, GIF, BMP, HEIC, TIFF and AVIF, whichever page you started from. Just drop your file and it converts.
