Combine files to One PDF document

Imagine a situation where you are dealing with multiple documents on a project or client or presentation. Under those circumstances, multiple documents would just work better as a single file. In fact, in typical workplace or business environment, multiple documents naturally belong together. For instance, quotation, sales order and invoice, or an email and its attachments. In short, combining such documents together makes it easy to see their relationship. In this article, learn how to combine multiple files into one PDF document using PDF Converter app.

1. Combine multiple documents to a continuous one PDF file


  1. Select your files in Windows Explorer.
  2. Right-click the selected files to show the context menu.
  3. Click ‘Combine to One PDF‘ menu. And choose ‘Convert and combine all files into one continuous PDF file‘ option from the dialog box and click ‘Continue’.
  4. From the ‘Save As‘ dialog box, enter a name of the PDF file.
  5. Finally, click ‘Save‘ to continue.

Consequently, the converter does the conversion of all the different documents into PDF pages before merging into one continuous PDF file in the background. That is, without prompting any further dialog boxes, inputs or clicks.

And what you get is a PDF file, with table of contents, that lets you jump quickly to individual document.

2. Embed and assemble all files of a folder to a PDF Portfolio

Consider a project you are working on with different types of documents – word, excel, powerpoint, images, archived ZIP etc. And quite often, you may require all these documents in their native (original) formats but embedded or encapsulated within a main PDF document file (such as a summary report file). Such PDF document is known as a PDF Portfolio. In short, the documents will appear in their original formats as attachments in the PDF file.

For instance, consider a list of different document types on your project (screenshot below) that you want to embed in their original formats in a PDF file.


  1. Select the multiple files from the folder and right-click.
  2. From the context menu, choose ‘Combine to One Pdf
  3.  Choose the ‘Embed and Assemble the files into a PDF Portfolio‘ option from the dialog box. And click ‘continue
  4. From the ‘Save As‘ dialog box, choose a folder path and name of the PDF file to be created.
  5. Click ‘Save‘.

This will create a PDF portfolio with the selected files embedded or assembled to the PDF document in their native or original formats.
