When should you merge PDFs?

Merging is useful when a report, application or project contains several separate PDF documents that need to be shared as one file.

Steps

  1. Open Merge PDF.
  2. Select the PDF files in the order you want them combined.
  3. Check the file list and remove anything unnecessary.
  4. Start the merge and download the resulting PDF.

Before sharing

Open the final document and check page order, orientation, bookmarks and file size. If the merged file is too large, use a PDF compression tool after merging.

Privacy reminder

Do not upload confidential material to an online service unless you understand how that particular tool processes files. Use local processing where available for sensitive work.
