JPEG & PNG files aren't quite ready for laser cutting. 

Lasers need artwork made up of vector paths rather than pixel based images.

If you can source or export vector design files from your software then that will work out best. We currently use DXF, AI, SVG or EPS files.  More about this here.

Here are some other ways to get files.

Alternatively, as a quick fix you can convert simple images to vectors.

How to convert simple images to vector artwork

Make sure your image is a single solid color rather than a line drawing to prevent duplicate cutting lines:

No software (online) 

Convertio:

  1. Upload a black and white PNG or JPG to https://convertio.co/ 
  2.  Convert the design to an vector EPS
  3. Download the EPS and upload it into your Ponoko account.

PNG to SVG

  1. Upload a black and white PNG to https://www.pngtosvg.com/
  2. Set the options to 1 color and what ever simplification settings make sense
  3. Download the SVG and upload it into your Ponoko account

Software: Adobe Illustrator (paid software)
Function: Image Trace

Software: Inkscape (free software)
