Any freeware apps to convert JPG to PDF?
If you don't mind my prying, why would you want to make that conversion? The JPEG is already in a lossy format, so any further conversion will likely degrade the image.
Actually, the images wouldn't really be "converted", the PDF file acts as something more like a wrapper that leaves the original jpg data untouched. Of course, you could then compress the resulting PDF, which would typically involve compressing the images contained in the file.
That still leaves the question of why convert to PDF at all.
You can put multiple PDF pages into a single document, for example. So stack of JPG photos becomes a single document.That still leaves the question of why convert to PDF at all.
I haven't done it that often, but when I have done it, it is because I have a collection of pictures and I need to point things out in an order. Thus I throw them into a PDF (using Preview) and then add arrows, text and other callouts that way. Then just distribute the PDF and it stays the way I wanted it to look.
But that's not all that common. Oddly enough, I had to do it earlier this week.
