Should You Use Online Apps? 

So, you want to learn how to combine PDF files. If you consulted Google first, you would find a bunch of online PDF converters. Most of them are free to use so you can combine and even edit your files. While you can use these services casually, we highly advise practicing caution in selecting ones that can preserve your privacy and data security.  Many online converters collect your metadata (the hidden information within your documents) to use for profit. Whether it’s through selling or utilizing your data in some way, free services like these always come with a catch. They may even find identification about you and the system you’re using. Therefore, it’s best to use trusted methods on both Windows and Mac. Usually, learning how to combine PDF files on Windows will require you to download a third-party app. On the other hand, Mac users have a native combine PDF function so it’ll be a lot easier for them. Either way, we don’t recommend you use free online services for your PDF files unless you’re truly desperate. Nonetheless, we’ll still include a tutorial for that in case you need it.
