Common Problems and Easy Fixes
Sometimes things don’t go smoothly. These are the most typical problems and their solutions.
Problem 1: The Pages Are in the Wrong Order
Fix: Most tools let you drag files into the right order before merging. Always check the order before you click “merge.”
Problem 2: One of the Files Is Password-Protected
Fix: The file must first be unlocked. Then upload the unlocked version and merge it like normal.
Problem 3: The File Is Too Big to Upload
Fix: Compress your PDFs first. A smaller file uploads faster and works better with most online tools.
Problem 4: The Final File Looks Off
Fix: Check that all your PDFs use the same page size (like Letter or A4). Mixing sizes can make the final file look uneven.
Problem 5: The Tool Asks for an Email or Signup
Fix: Skip those tools. Use a free PDF merging that respects your privacy and doesn't require you to join up.

Desktop software:
