Using Scan2CAD to convert JPG to G-Code
How it works
- G-Code Bezier Options: cubic splines, arcs or polylines
- Arc and Circle Rotation: clockwise or anti-clockwise
- Z Settings: Z offset, Z max for passes, Z limit per pass and Z retract per pass
- Scale Settings: setting the required scale, e.g., inches or millimeters.

- Only pick images with high resolution. If it’s pixelated, you should look for an alternative.
- Try for a better raster file format. JPGs aren’t the best file format—you might look towards using a TIFF instead, taking advantage of its lossless compression.
- Less is more. Try to use images with as few colors as possible. For CNC in particular, 2-bit color is a necessity.
- Clean, clean, clean. Avoid images that have blurred areas, shadows or any overlap—it will only cause issues during vectorization.
- Avoid compound curves. CNC machines aren’t big fans of curves (splines, ellipses), and instead prefer polylines which only include line and arc segments.
Pre-conversion tips
- Thresholding is key. By using Scan2CAD’s thresholding tool, you can reduce the colors in your image to just black and white, making it easier for the software to detect the entities in your raster. You can choose between simple and adaptive—the latter of which enables you to define the point at which pixels are classed as “black” or “white”.
- Remove speckles and holes. You can easily remove stray pixels with the despeckle tool which allows you to erase pixels that are larger than a certain amount. Just as easily as you can get rid of speckles, you can also fill in any holes to make solid objects.
- Thicken lines. If you’re looking to convert JPG to G-Code, you need an image without gaps or broken lines. The thicken lines tool makes this a problem of the past. Be sure to look over your image carefully, however: you don’t want to accidentally join lines that are meant to be separate.
- Smooth image. If your image has too many “hairs” around the edges, you can use the smooth tool to—yes, you guessed it—smooth out the edges. This will stop the software from drawing vectors around these hairs.

Why would I need Free DXF Files?
There’s a lot of fun to be had with decorative and artistic CNC projects. Such projects don’t require a lot of precision and are only 2 to 2 1/2D, so they’re easy to make with a CNC Router, Laser, Waterjet, or Vinyl Cutter. Sometimes we’re adding a design as a decorative element on top of a precision machined part, like this engraving on a bandsaw mitre gage:
Many times, the hardest part of these kinds of projects is coming up with artwork. It’s line art, which is relatively straightforward to convert to CAD and thence to CAM and finally g-code. But getting decent line art to start can be a pain. Especially for non-artists.
With this page, I’m making decent quality line art available for free to CNC’ers.
As you can see, we divide the files into Categories like Animal, Holiday, and Vehicles. I have a LARGE library of free dxf files that you’ll be able to download above. I don’t have nearly all of them up yet, but I will be steadily adding to the page until I have them all available.
Below, you’ll also find information about how to get the most out of the free dxf files, so be sure to check out the article below on optimizing your CAM for DXF Cutting Files.
I have big plans for the page, so stay tuned. If you haven’t already subscribed to our email newsletter, get hooked up right below so you don’t miss out as new developments unfold.
Optimizing Your CAM for DXF Cutting Files
To ensure you have an excellent experience with our free DXF files we would like to share with you some information that will make it easier for you to be successful with our DXF files.
The first thing you will want to do once you download a Free DXF file is to unzip the file with a file extraction program. Once you unzip the file folder you will see two files available. One of your unzipped files will end with .dxf and the other will end with .jpg (.dxf files are for cutting .jpg files are for viewing purposes only).
You will primarily be focused on either importing or opening the DXF file into your CAM or CAD based software program. If you are trying to edit the design work you can use a program like Corel Draw or Adobe Illustrator to make quick changes to the existing DXF file.
I know a lot of individuals that are new to the CNC industry like to try Inkscape but I have not had very good success with importing and opening my DXF files into that particular program. I believe it is due to how Inkscape was developed based off older versions of the DXF file format.
