Compression of PDF - e.g. Bible shorter than .txt

Dear Community

I found the (german) Bible under https://info2.sermon-online.com/german/MartinLuther-1912/ 

In this the PDF-version (3'736 KB) is much shorter than the TXT-version (4'368 KB) :

 Martin_Luther_Uebersetzung_1912.pdf2016-03-15 08:093.6M
 

 

Martin_Luther_Uebersetzung_1912.txt2014-02-03 00:064.2M

I counted the character (of the pure text) and found 4'016'646 charachters in the TXT-version. The PDF-version is less (3.6M only). How is it possible? 

Thanks for any explanation.

    This is the result of text compression.

    Does PDF not need 8 Bit per character?

    A PDF uses more space than TXT but then it is compressed. To oversimplify, parts of the file as ZIP compressed. ZIP your text file, it will probably be smaller still.
