I have a PDF file containing the cards for my game - OptrixAU/printathome-python GitHub Wiki
Currently, PrintAtHome doesn't offer the ability to convert a number of formats to images.
I have a PDF file
However, you might be able to use a web converter, such as https://pdftoimage.com/ to convert the pages in your PDF to .JPG or .PNG files, which the program can work with.
I have a DOC file
Word won't let you save to image files, which is a bit of a shame. One work-around is to save your DOC as a PDF, and then use the steps above to turn them into a JPG.
I have an SVG file
Packages such as Inkscape and Adobe Illustrator should help you turn your SVG into a PNG or JPG.
