I want to use progressive jpg files and want to know if craft image transforms save jpg images as progressive, or can they be made to?

You can achieve progressive JPGs if your server has Imagick installed, but it doesn't look like the image processing library that Craft is using has added support for it, yet.

Does this mean that one day Craft will support transforming progressive JPGs? Provided Imagick is installed of course. Nov 21, 2014 at 14:10

Yes. At least in the current version (3.2.6+)
On the image transformation page, you can select one of the interlacing methods under the "Interlacing" heading. I'm not exactly sure the differences or pros/cons of each but I've used "Partition" and it works well.

This doesn't seem to do anything. Images are still nog progressive. Jan 13, 2020 at 7:52
