Yes, and phpBB is not one of them. Technically this implies not only carrying over the EXIF data but also adjusting it (size and height attributes) and supporting every picture format that supports EXIF (not just JPEG).
JPEGs naturally are compressed heavily already - compressing them further downgrades quality. PNGs, GIFs, TIFFs and WEBPs can't be compressed any further.
What do the numbers say if you download that same image from the server to your desktop?
