This is not enough to remove metadatas, there are white text
watermarks sometimes, classic text
watermarks (like "downloaded from…"), comments watermarks (pdf format comments, not the one you see on
Adobe products) which are invisible except when you open the file with
a text/hex editor…

I think the best way to find which kind of watermark you have is to
compare two files from two different providers if it's possible.
