Create a Table of contents for PDF merge

You would like to prepare a merged PDF bundle containing multiple PDF documents. 

Here’s a tip on how to improve your process: make the combined PDF easier to navigate by adding a table of contents, auto-generated based on the files that you are combining.

We’ll use Sejda’s PDF merge tool:

1. Select your files

Drag all files to the web page.


2. Enable table of contents generation

Click More options and the select the option to generate a Table of contents based on the filenames. Alternatively, you can also try using document titles.


3. Merge and download your result

Click the Merge PDF files button and then when the task completes click Download to save your merged file to your local computer.


Online Service or Desktop Application

Nowadays offices moved completely in the cloud and Chromebooks are becoming popular. 

The Sejda PDF online services integrate with Google Drive and Dropbox so you can process files from your Cloud storage and save them back when done.

There are scenarios where uploading sensitive files to a third party service is not allowed. Files cannot leave the corporate network and a desktop application that processes the files locally is requred.

Sejda PDF offers a desktop application that has the same features as the online services but the files are processed locally, not in the cloud.

Sejda Desktop is free to download and use with daily limits. Power users that reach these free limits are asked to upgrade.

Form fields when combining PDF files

The use case: I have 20 filled out forms with the same structure but different data sets. I’d like to archive them by merging them all into one document.

Most PDF merge programs will not handle properly having multiple form fields with the same name in the same file. Sejda’s PDF Combine tool handles this nicely by default, without extra configuration needed.

More you can even opt to flatten out the form fields, meaning the value will be displayed but the form field will not be editable anymore. Even better if you’re archiving the form and want to preserve the current filled out values.

Double sided print friendly

When you’re merging a 3 pages document with a 6 pages document you get a merged PDF document that can’t be nicely printed double sided, since the first page of the second file will now be on the back of a page belonging to the first merged file.

Sejda’s Merge PDF has the option to prevent this, by adding a blank page if the document being merged has an odd number of pages.
