Compressing multipage TIFF files

I have several multi-page TIFs (b&w documents), which I would like to compress using the Group 4 compression. However, Xnview seems to compress only the first page of the document, while the other pages are "ignored".

Is there any easier way to compress a multi-page file, than splitting the document into singular pages, converting all the pages and then joining them back together?

Thanks.

The XnView Classic and XnView MP browsers both have options for multi-page files to extract the pages, and to create a new multi-page file from those pages after compressing them; you could probably use batch convert to compress the files if there are many of them. [Caveat: I don't have XnView Classic in front of me as I'm on my Linux laptop.]

But there is probably an easier way to do what you need: The batch convert function in XnView MP (or XnConvert, the attractive standalone batch conversion utility) can be configured on the Output tab to convert a multi-page file directly to a new multi-page file, after performing the desired operations, in your case just changing the compression. But study the setting carefully! :D
