Extracting certain pages from a PDF document doesn’t have to involve document-viewer software. In fact, Google Chrome alone lets you pick one or more specific pages and extract them as a brand new PDF document. Here is how you can achieve that.
1. Launch the PDF document on a browser like Chrome. You can do that by right-clicking on the file > Open with > Google Chrome.

2. Click the Print button or press CTRL+P.

3. On the Destination, select Save as PDF.

4. On the Pages, select Custom.

5. Select the pages you want to extract.

6. Click Save.

7. Give it a name and hit Save.

Now, a new PDF file has been extracted, containing just the pages you select before.
