Uploading pdfs to canvas readability

[suzanne_hoehne]

My professor says that my uploaded homework is not easy to grade using the canvas application . It is too large scale, he has to scroll all across the page.  I upload the homework by taking a photo with my phone and then creating a pdf with adobe using a computer.  I do not have the capability to download apps to my phone.  Is there anyway to make the file work with canvas better for him? 

Thanks.
