Insert Pages into Multiple PDF Documents

Introduction: It’s often necessary to add PDF pages to multiple documents, but doing this manually for many files can be time consuming. Examples of this procedure may include adding a ‘welcome letter’ to the beginning of multiple documents destined for different recipients, or appending ‘Terms and Conditions’ or other required information to multiple PDF's. Using this method, the inserted pages are always identical, but the documents they are added to may be different. Also use this tool to configure the output document filenames once pages have been inserted, as well an output location for merged files.
Input Document Description: The sample files used here are invoices named only by each customer name. The goal is to insert a stub page saved as a separate PDF, displaying “PAID/SHIPPED” text into each document. This can be placed either before or after the existing pages of each invoice.
Prerequisites: You need a copy of Adobe® Acrobat® along with the AutoSplit plug-in installed on your computer in order to use this tutorial. You can download trial versions of both Adobe® Acrobat® and AutoSplit™.

Step 1 - Opening the Tool: Start Adobe® Acrobat® and select “Plug-ins > Merge Documents > Insert Pages into Multiple Documents...” from the main Acrobat menu.
Step 2 - Select Input Files: Press “Add Files…” in the “Select Input Files” dialog to select files that need to be renamed. Consider also keeping backup copies of the input files before processing.; Select the PDF files that need to have pages inserted and click "Open" once done.; Selected PDF files will be listed in the "Select Input Files" dialog. Note that files from multiple folders can be added with repeated use of the "Add Files..." button. Click "OK" once all necessary files have been selected.
Step 3 - Select Pages to Insert: Click the first "Browse..." button to select the PDF file that contains the page(s) to be inserted.; Select the necessary file and click "Open".
Step 4 - Select an Output Location: The number of pages that will be inserted into each document is now displayed - "Number of pages to insert: X".; Click on the second "Browse..." button to select an output location for files containing the inserted page(s) to be saved in.
Step 5 - Select Processing Options: Use the checkboxes to select additional processing options:; If checked, "Save merged files into the same folder as each input file" will disable the manually selected output location options. Newly combined files would then be saved in the same location as the original input documents (i.e.: the invoices in this example).; Along with the above option, use "Allow overwriting of existing files" to replace the existing input documents with the new merged versions that contain the inserted pages.; The plug-in also provides an option to create a detailed HTML processing report that lists each successfully created file. Select this option to create the report, which will be a saved in the same output location as the merged files.
Step 6 - Configure Output Filenames: Use the "Output File Naming" section to configure a format for output filenames to follow. Text inserted into the "Insert Before/After" boxes will be placed in each output filename. In this example we have entered some custom text to be added before the existing filenames. The resulting filenames will appear like this: "CustomerInvoice_Ann Johnson".
Step 7 - Select Where to Insert Pages: Use this section to select where inserted pages will be placed. By default, inserted pages will be placed after the last page of the existing document. To place them before the first page, select this option from the drop down list.
Step 8 - Confirm the Procedure: Click "OK" on the dialog once all settings have been configured.
Step 9 - Review the Processing Report: A report box will confirm the success of the operation. Clicking “OK” will open the HTML processing report if the option to create one was previously selected.; The processing report lists detailed information about all merged files, along with input/output file names for each document.
Step 10 - Inspect the Results: Open the relevant output location to check the created files. The plug-in will have automatically named all files using the configured format. The HTML processing report will also have been saved in this location.; Open the files to inspect the inserted pages. In this example, the stub page displaying "PAID/SHIPPED” text has been placed before the first page of each invoice.; You can find more AutoSplit tutorials here.
