Despite the fact that this method is quite popular among users, we do not recommend it. Indeed, online tools that adjust size of PDF pages are usually quick and free, but there are also enough drawbacks: from reduced quality and sloppy formatting to the inability to set custom output file parameters.

Here's how to adjust the page size of a document with Nitro PDF Pro:
