PDF file format recap

PDF files are on the scene since the 1990s, which is quite a long time. Somehow, this type of file format fights the logic and never losses its popularity. PDF file format became a standard for document representation. It can be opened with almost every existing software and operating system.

PDF file format can contain text, images, hyperlinks, rich media, digital signatures, form fields, attachments, metadata, and even 3D objects. It is easily shared and transferred via popular platforms and across social media. However, it is often a lot easier creating a Word document and converting DOCX to PDF than creating PDF documents from scratch.

Another way to merge PDF files…

The main reason why we don’t count this one as a ‘regular’ how to merge PDF files way is: we don’t work with PDFs directly. The whole idea is to take several documents and put them together in other programs like Word and convert them back to PDF. Sure, it might take more time than previously mentioned ways, but it gives you the option of additional editing. In the end, that fact might come quite handy.

So, step number one is to convert files to Word or any similar type using a PDF converter. Then, merge those documents into one using the good-old copy/paste method or any other known to you. Now, you can fix everything that is broken and edit what needs to be edited.

In the end, just convert those files back to PDF file format, and you are done. It’s not the fastest way to do things, but it gets the job done.


PDF files are used widely, and because of that, there are plenty of online and offline tools that can help you with editing, merging, and creating PDF files. Finding the right one for your needs is sometimes a challenge, but the world of the internet can help you with that.
