Progressive JPEG Changed Filesize

Hi AWS Team!

AWS supports Progressive JPEGs?

I was using AWS Ruby SDK for Rails app

When the User upload Progressive JPEG through app and then download it back through app - filesize changed

Then I check image metadata, and noticed that jpeg format encoding was changed from Progressive to Baseline and filesize grows for some(looks like it also due to encoding change)

I was able to reproduce it in local development, I tried .jpg .jpeg .pjpeg file extensions(all of these files have Progressive format), but it still changes encoding to Baseline

Is this a change from AWS side? And if so, what can you advise?
