Bug Description
I have noticed that the much awaited Embed Metadata button for PDF's (thank you, Kovid!) quite consistently (though not always) adds 0.5MB to book size, way more than would have been expected (a 1.1MB book becomes a 1.6MB book, for example).
Interestingly, this 0.5MB can be then made disappear by resaving the pdf with Adobe Acrobat Professional, for example.
Not sure what's going on, but it does seem like a bug and not a design feature, though I am not sure exactly what is being embedded or how.

I cannot reproduce this. Steps I tried:
1) Download a minimal PDF file: brendanzagaeski .appspot. com/minimal. pdf (739 bytes)
http://
2) Add it to calibre and add some metadata
3) Use the embed metadata tool
4) The PDF filesize becomes 17KB (an increase of ~16KB nowhere near
500KB)
Embedding metadata embeds *all* the mettadata for that book present in
calibre, this means all the standard fields,m comments and all custom
columns. Assuming you dont have a book sized comments field pdf filesize
will typically increase by 10-20KB.
