I created the image in canva and saved it, but it didnt save as a PDF. Does it have to be a PDF to edit in adobe? If so, Can you please tell me how I save it as a PDF? i didnt see the option in Canva.
Yes. Once you have saved it on your computer from canva. Open Adobe and open a new PDF with the image. Then go to the print in adobe and edit it as a poster in Adobe. Before hitting the print button
