Frequently Asked Questions About Joining Multiple PDFs

There are many reasons why you may have come across two or more PDFs instead of just one. You may have exported each page to different .pdf files, or you might have edited one of the sheets and when doing so, you generated several files separately. Luckily, you can merge PDFs into one document.
No, there is no limit to merge files. A PDF is a document that can have as many pages as you want. Thus, you can upload as many PDFs as you want to join them in one single file. Once you have joined them, each PDF will be shown in a different page (or several pages if the file had more than one).
The more pages the PDF has, the more space the document will occupy. If you want, you can compress the resulting PDF after joining so that it weighs less. In any case, the file should not take up twice as much space because the files you are joining share a lot of information in the .pdf extension that doesn't need to be duplicated.
Yes, you can combine PDF files that, in turn, will join a JPG within the same document. You can create your PDF document by mixing existing files with photos that you want to add to the pages.
No, the document's extension when joining several different PDFs will not change. You can join, combine, and group PDFs without changing their file extension. The resulting file that you can download will remain a .pdf file.
No! You do not need to install any program, with our online tool you'll get the same result as with any paid program. In addition, it has several advantages as it is free, doesn't require installation and operates from any device.
