Coolmuster PDF Merger

If you're looking to combine multiple documents into one, more than a few options are available on the market. There's certainly no shortage of PDF merger apps out there, so all you have to do is find the one that's most suitable for your use cases.

Coolmuster PDF Merger is a relatively simple tool that should get the job done without requiring much effort from your part. It features a modern interface where users can add the documents they wish to merge, which the tool should be able to combine within seconds.

Seeking to make merging multiple documents easy and intuitive for users, the program is essentially as simple as it gets: boot it up, locate your documents through the interface, and choose the output folder. It's worth noting that dropping our files onto the interface did not work for some reason, which is why we found locating them via the program to be more reliable.

Nevertheless, you also get a preview window of sorts, which serves to show you a quick look at the highlighted document. This can help minimize checking the wrong documents for the merging process, so it's a nice-to-have feature overall.

We encountered no problems when it came to merging documents. The tool was quick to respond, and there wasn't really any delay in getting our files combined.

The Free version comes with some limitations, but they don't render the app unusable. As it stands, Free users may only merge their PDF documents only 3 times, after which they'll have to pay to continue using the app.

Coolmuster PDF Merger's main — and only — usage is combining multiple documents of yours into one. To that end, the program is simple to understand, and should do a good enough job for most people.
