Imagine a situation, where your scanner produced individual pages of a document while scanning, or you have multiple documents that would just work better as a single file. In fact, in typical workplace or business environment, multiple documents naturally belong together, such as quotation, sales order and invoice, or an email and its attachments. Combining such documents together makes it easy to see their relationship.

Combine files to One PDF document

With File to PDF app, to create one PDF file from multiple documents, select multiple files in Windows Explorer. Right-click and click ‘Combine to One PDF‘ menu. And the File to PDF app does the conversion and merging of all the selected files in the background without prompting any further dialog boxes, inputs or clicks.


And what you get is a one PDF file containing those selected documents in the sequence you have selected – all converted to PDF format themselves. Table of Contents or bookmarks are also automatically added to the final one PDF file for easy reference of individual document. As of this writing, more than 120 types of documents, including compressed ZIP file (which contains child files within) were supported for seamless conversion to PDF without external dependencies.

For finer control, you can also click ‘Convert/Save to PDF (Advanced)…’ menu.

This will take you to the advanced mode window. Within the section ‘Combine All to One PDF in‘, choose one of the destination option and change the one PDF file name if necessary. (Default is ‘MergedDocuments.pdf‘). You can re-arrange the sequence of the documents, add password to the PDF, put your company logo or brand name as watermark as well as change the page layout.
