How to Merge PDF Files

How to combine PDF files

Below we show how to combine multiple PDF files into a single document.

Upload your files

Files are safely uploaded over an encrypted connection. Files stay secure. After processing, they are permanently deleted. Rather not upload your files and work with them offline?
Try Sejda Desktop. Same features as the online service, and the files never leave your computer. Click 'Upload' and select files from your local computer. Dragging and dropping files to the page also works.

Dropbox or Google Drive files

You can pick PDF files from Dropbox or Google Drive too. Expand the 'Upload' dropdown and select your files.

Reorder your files

Drag and drop the files to change the merge order. Use the sort buttons to sort alphabetically on filenames 'A-Z' or 'Z-A'

Double sided printing

Generate bookmarks or outline

You can customize how the PDF file outline will be merged. There are 4 scenarios to choose from:

  1. 1. Discard all
  2. 2. Keep all
  3. 3. Discard existing and create new bookmark per file
  4. 4. Create bookmark per file keeping existing under

  • How to add filenames to page footer

    You would like each page from the merged PDF file to have the original filename in the footer. Click 'More options', then select the 'Add filename to page footer' option.

    Generate Table of Contents

    You would like to have the first page as a Table of Contents, with clickable links that navigate easily to the starting page of each merged file. You can choose between using the filenames or the document titles in the Table of Contents. Click 'More options', then select the 'Based on file names' or 'Based on document titles' options in the 'Table of Contents' section.
