How to Choose the Best One 

The biggest drawback of online tools is that files must be shared online. Although companies promise to delete uploaded data quickly, users do not get any proof. Offline combiners are more secure, as PDF files will never leave your computer. 

If you have just a couple of light documents, converting them online is acceptable. Many tools from our top 12 come with versatile additional features. Apart from merging the files, you can split them, convert, protect, and edit. Take advantage of free trial periods to see how the best combiners work in practice.
