How to Create an Icon From a JPEG. Converting your favorite JPEG images into icon files gives you full control over the appearance of icons on your business desktop.

To convert a JPG file to a PDF file, simply change the file format on your computer's default photo-viewing app.

If you do that, then any image you try to AirDrop will already be in JPG format. To do that, you'll need to configure your device's Settings app to save images as JPG files.
