What should a JPG to PDF app do?

- Take many images at once. Gallery images need an app that takes them all and sets the order. PDFriend takes up to 100 in one pick, and Smart Scan handles paper too.
- Keep the file on the phone. An ID card, a contract or a medical letter should not go to a server. PDFriend makes every PDF on the device.
