PDF file size has been increased sharply in recent years due to mass usage of images in PDF documents. This has less impact for computers, which has much more powerful CPU and more memory storage. However, this could be a big problem for reading large PDF on portable device like smartphone or tablet. The most notable issue is app craching when the PDF file being opened. So reducing or compressing PDF file size is necessary if you encountered such an issue.

This method is easy, but not very convenient because you'll have to merge the individual pages again to get a single document. However, it is helpful when you only want to send part of a PDF to someone else, or if there is a size limit in your medium of sharing. For example, some email clients won't let you attach large files, so it's better to break up your PDF or cut it into smaller parts. To do this in a Mac, you don't need any additional tools. The built-in Preview app has a feature that can do the job.
Step 1. Launch the Preview app and open the PDF document.
Step 2. Make sure you have thumbnail view enabled. If you can't see the thumbnails on the left panel, click on the View Menu icon on the top left and select Thumbnails.

The only problem is that this method is not convenient if you have a lot of PDF pages to compress. Besides, organizing them into folders so they can be put together again properly will take up a lot of time. A much easier way is to use a software application like TunesBro CleanGeeker.
