How to merge documents of different formats into PDF

While we no longer have to wrangle so much physical paper as part of our day-to-day office work, this doesn’t mean we are finally without difficulties when it comes to storing and sending information. Online documents indeed give us speed and efficiency, especially when it comes to collaborative work; but nonetheless, no one likes to receive an email with 15 documents attached, or a link to a Google Drive folder with disparate information spread throughout a mix of spreadsheets, Word files, and PDFs.

PDF format: Pros and cons for business documentation

PDF pros

  • Incorporates lots of different elements - In general, PDFs are best able to demonstrate their worth when they are complex documents made up of text, borders, tables, images, and other graphic elements. All these parts can be easily formatted within the one page.
  • Can be viewed on any device - PDF, standing for portable document format, contains all elements within the file itself, unlike with other document types. This simply means that the PDF will render in exactly the same way, no matter the device, browser, or software used to open the file. Especially for financial documents with precise figures, this is extremely important.
  • Secure - PDFs can be password protected, giving sensitive documents a layer of security that is not present in some other document types.

Despite the obvious benefits, there are of course some drawbacks.

PDF cons

  • Large files - While this is less of an issue now that storage is becoming cheaper and internet speeds faster, the issue of large files is nonetheless a consideration. As we mentioned above, the portable document format packages all elements into the file itself, meaning that sending and storing documents could present more of a challenge than the very small file sizes of other document types.
  • Editing difficulty - PDFs are more difficult to edit than other documents, especially text, which is perceived as pictures. That being said, ever since the PDF became an open standard in 2008, a large number of tools have been created that deal with this issue, making creating and editing PDF documentation a much easier affair than previously.

To sum up this section, PDFs are a staple of the modern workplace and for good reason; however, only with the right software can you effectively harness their true power. In the next section we’ll take a look at converting and editing PDFs and the tools you can get to do it!

Luckily, there are a whole range of tools available that allow you to convert and merge PDFs online, three of which we will talk about here.
