How to Combine PDF Files
When you have multiple PDF files that you'd like to combine into a single document, PDF Combine is without question
the best tool for the job! Our user-friendly interface offers several different ways to accomplish this task. With PDF
Combine you can choose between combining PDF files individually, based on folders or by selecting a common name
part. To learn more, continue reading.
1. Begin by launching the PDF Combine app.
2. Next, locate the files you plan to work with (these
can include single files, entire folders or both!). On
the left side of the main interface, you'll notice a
list of available locations to choose form. After
selecting a folder, a secondary list will appear that
includes its contents.
TIP: the Include subfolders and Check / Uncheck buttons
at the bottom of the interface can save time by letting you
select and deselect large groups of files all at once.
3. After you've checked the box next to each file that
you plan on working with, click the Combine to PDF
button at the top of the PDF Combine window.
TIP: the Filter feature lets you easily select a single format
type (i.e. HTML, PDF, DOC, TXT, XLS etc.) and filter File
Name results so that only that one format will be shown.
TIP: the preview window lets you verify the contents of
your files before deciding whether to include them.
Using the Zoom In and Zoom Out buttons you can adjust
the size of the document preview.
Clicking on Actual size let's you quickly toggle to max
resolution view. For more resizing preview options, take
advantage of our Whole page and Fit to width functions.
4. This will open the options view. By default, the options window will start with the Destination tab. From here
you can name your new PDF document and choose the destination pathway where it will be saved after
combining. Additionally you choose whether to Combine all into one document, Combine files by folders or
Combine by common name part. See below for more info on these three options.
Combine to PDF Destination Options
Combine all into one document is the default option in the destination view. When this option is selected, all of the
individual files that you put a check next to in <step 3> will be merged into a single PDF file. By default the finished PDF
document will appear in the same folder as the original documents you chose to merge.
Combine files by folders lets you merge files together within folders. If you have 2 folders with 10 PDF files in each, with
this option you will get 2 multi-page PDF files. Your new PDF document can be placed in an entirely new . That's name
and location will depend on the destination you specified in the Folder field.
Combine by common name part lets you combine multiple files that share certain commonalities in their names. For
example if one file is named "543451_auto_ABC.pdf" and another is named "543451.pdf" you can set PDF Combine to
locate both files based on a search query for "543451" and the app can automatically locate and combine them.
TIP: clicking the box next to Keep folder structure will maintain the original file architecture when combining their
contents into a single PDF.
TIP: clicking the [...] to the right of the Folder field will provide you with an expanded view of your drive(s) navigation
structures. This can serve as another quick way to locate and access files/folders.
How to Change the Order of PDF Files
Part of what makes PDF Combine so easy to use is its ability to give you an overview of all of your files. By default, your
file lists will appear in alphabetical order -- the same as on your computer. However, there are a variety of ways
available that allow you to change the order in which files appear in the file selection frame.
Method One: Reordering Files by Category
1. Begin by launching PDF Combine.
2. Next, in the left sidebar, locate the folder that contains the files you'd like to work with. After you open that
folder a list of its contents will appear in the file selection frame.
3. At the top of this frame are several tabs that let you reorder your file list based on different criteria. For example
if you click on File type ^ files in the list will be reordered alphabetically according to what extension they share.
Similarly, clicking on File size will reorder your file list based on their size, and so on.
Method Two: Changing Which File is Highlighted
4. With PDF Combine open and a folder selected, place a
check next to the file you want to move.
5. Next, click Edit in the topmost menu to reveal a
feature list that includes Move Up and Move Down.
This lets you change which file is checked by
highlighting (and moving) the checked box above or
below the currently selected file.
TIP: right-click the highlighted file to access the same
Move Up / Move Down functionality.
TIP: it is also possible to reorder files using the
traditional drag & drop method. Simply left-click the file
name and hold. Then with your mouse, drag the file up
or down to a new location in the file list.
How to Create Bookmarks
Adding bookmarks to your PDF file is a great way to help your readers navigate the document; especially when your PDF
includes the content of many different PDFs merged into a single file. Bookmarks can serve many different purposes.
For example, the bookmarks feature lets you create a glossary, an index or even a table of contents.
When a reader clicks on a bookmark, the PDF will automatically switch views to display the relevant content that is
associated with that bookmark. In other words: instead of scrolling from the top of the PDF all the way down to page
137, a bookmark lets you jump to page 137 in a single click.
1. With PDF Combine open - and your files selected, click
the Combine to PDF button in the top-left of the
2. Next, click the Bookmarks tab in the left sidebar. This will open the Set bookmark style options view.
TIP: Notice the Do not add bookmarks option is
unchecked? This means that unless you specify
otherwise, PDF Combine will add bookmarks to any
qualifying multipage PDF by default.
3. Here you will see several options that let you choose whether or not to include bookmarks, and how those
bookmarks will behave within your PDF. To learn more about how the different bookmark options work, see
Bookmark Feature Guide
This guide will give you a brief idea of how the different options function. For the most part, the bookmark options are
designed to let you determine how your bookmarks will be structured after combining your PDFs into a single
Use file names lets you generate a set of bookmarks that share the same name as the original files they were created
from. Although your PDF will be a single document, your readers will be able to identify and quickly jump to individual
documents within the larger PDF.
Use document titles is similar to Use file names in that it lets you structure your bookmarks based on naming
conventions associated with the original documents being used to create the PDF. It differs slightly by allowing you to
name bookmarks based on document titles instead of file names.
Use external file with captions lets you use your own bookmarks. Put a list of desired bookmarks into a TXT file and
upload it to the program:
Do not add bookmarks lets you control whether or not the PDF will include bookmarks. Because the bookmarks feature
is so helpful, all PDFs will contain bookmarks by default. However, there are situations in which you may not want to use
bookmarks and this option lets you turn the bookmark feature off prior to combining files.
Use folder structure lets you mirror your bookmarks after the structure of the original folders included in the PDF prior
to combining. This feature can help to maintain folder architecture and is generally recommended so that when you do
view your finished PDF, everything will appear in its right place.
Save PDF bookmarks lets you keep track of what you worked on last by letting you save previous settings.
How to Create Table of Contents
Closely related to the Bookmarks feature, including a Table of Contents in your PDF adds a layer of professionalism on
top of producing a document that is easy for readers to navigate. Several options are built-in to help you customize the
look of your table of contents.
1. Begin by launching PDF Combine.
2. Next, in the left sidebar, locate the folder that
contains the files you'd like to work with. After you
open that folder a list of its contents will appear in
the file selection frame.
3. Place a check next to each file/folder that you plan to
work with and click the Combine to PDF button in the
4. Scroll down to the Contents tab and click to reveal the Content page properties view. From here you can adjust
how your table of contents will appear by specifying a font type and size as well as line style and color.
How to Sign PDF
Adding a digital signature to your document is a great way to let your recipients know that what they are receiving is real
deal. Signing a PDF document digitally can save both time and money by allowing documents to be authenticated
remotely. With PDF Combine, adding your digital certificate is quick and easy.
1. With PDF Combine open and your files located, click the Combine
to PDF button in the main toolbar. This will open the options
2. From here, click the Document tab in the left sidebar and
then click Sign. This will open the Sign PDF document
3. Here you can add any digital certificate that you have
saved in the PFX format. Click the [...] at the end of the
certificate field to access a view of your drive(s) and select
a PFX file.
4. Next you'll want to set a password. This limits who is able
to access and use your digital signature, thereby making it
impossible for anyone to fake your identity.
TIP: enter the password associated with your PFX file to
grant PDF Combine permission to access and use your
TIP: the Location, Contact and Reason fields are included to
help you provide more information. This lets users know the
who, where and why behind the signing of the document.
