2.2 MB for one page of text !

Hello,

I have done this :

1) I have created a A4 blank page in Acrobat Pro.

2) on another PDF I select a part of a text and click on "copy the image", so it copy the selected text. 

3) In the created blank page, in edit mode I paste this "copied image" (made of text).

I do the same with another text (I copy it and paste it inside the created blank page).

So I have this result in the created blank page (it is like a collage between two parts of text) :

Problem : this one page created blank page made of text only has 2.2 MB file size.

I have done "compress PDF", but I have always 1.7 MB for a single page of text.

Here are my settings :

I understand that this collage of 2 images of text makes this file being big (2.2 MB or 1.7 MB).

But my goal is to have something like 150 KB or 200 KB file size for one page of text (collage), while keeping good quality results. How to do this ?
