If you’re like most people, you probably use email to send and receive pdfs. But if you’re using an iPhone, there’s a better way: text. To send a pdf, just type “pdf” into the text field of your email and hit send. To receive a pdf, just type “txt” into the text field of your iPhone app and hit send. The best part is that you can easily share pdfs with others by sending them as text messages. Just type “send as text” into the text field of your iPhone app and hit send.
