As you may already have guessed just by reading its name, PDF Merge Tool is a tiny, smooth-running utility that allows you to combine and merge multiple PDFs.

As a matter of fact, that's not all this app is capable of doing. The app's highlight undoubtedly stems from the fact it's not only limited to merging PDFs, but it can join together a wide array of other files (in a single PDF file).

To be more precise, it allows you to combine up to five files (documents, ebooks, images, presentations, spreadsheets, vector files, as well as CAD files) by providing support for some of the most popular formats from each category.

For instance, it's capable of working with formats such as DOC, DOCX, HTML, RTF, TXT, PDF, AZW, CBR, CBZ, EPUB, MOBI, BMP, DNG, GIF, ICO, JPEG, PNG, RAW, TIFF, PPT, PPTM, PPTX, CSV, XLS, XLSX, EMF, EPS, PS, SK, and VSD, just to name a few.

In addition, it also provides you with the option to password protect any of the supported files.

Considering its support for this impressive collection of formats, it shouldn't come as much of a surprise that PDF Merge Tool does not offer any kind of options regarding the merging procedure, a classic example of WYSIWYG philosophy implementation.

On the upside, you get a modern-looking, smooth-running and quite useful application that's so easy-to-use that even the most novice of users should have no problems dealing with it.

To conclude, if you're looking for a straightforward tool for your Windows 10 device that's capable of combining various types of formats into single PDFs, then you might as well give PDF Merge Tool a quick try-out, as it gets the job done without requiring anything more than a few mouse clicks on your part.
