Troubleshooting
Common Merge PDF Problems
Why is the page order wrong?
File order and visible page labels can differ. Check thumbnails and page content before starting, then verify the completed PDF page by page.
Why did a page size change?
Source PDFs can contain mixed page boxes and dimensions. Review small, rotated and landscape pages after processing.
Will links and bookmarks remain?
Page operations can affect destinations, bookmarks and internal links. Test navigation in the result before sharing it.
Can I undo the operation?
Keep the original file. A downloaded result is a new document and should be checked before it replaces any approved copy.
