Imgur converts pictures less than 1 MB

Thanks, Sushubh. Everything you said was correct. Since you have a pro account, would you be able to verify that images under 5MB are not compressed?

Only in some cases when the image is really small it will not compress the image again. Heck, it compresses png's again to png's to save few KB's (that's fine, since it's lossless). What is more annoying that it does that to jpg's too and it ruins the quality.

Example (original: 324 096 bytes):

http://i.imgur.com/8xMK5.png (308 068 bytes)

JPG example: original 1920x1080 picture was 907 717 bytes, when uploaded it's 375 226 bytes and obviouosly looks like poop now.

File size is not a direct relationship to image quality. Every image that's uploaded goes through lossless compression (you can do this with jpegs too).

If you're really concerned with image quality then you're going to have to upgrade your account.

Of course, but in this case it's super obvious that they compress uploaded jpgs even further. Loss in quality is very noticeable. You can manipulate jpeg's losslessly (rotate) but you can not recompress it losslessly and make it 1/3 of the original size. I'm concerned that it will do the same with upgraded account.

I have only tried image resizing project after PDF to image conversion procss. Any suggestion will be appreciated. Thanks in advance.
