About Merge PDF
Merge PDF combines multiple PDF documents into a single file with preserved formatting, bookmarks, and page structure. This is one of the most common document operations for office workers, students, and professionals who need to assemble reports from multiple sources, combine signed contract pages, or create unified document packages for submission. The tool supports drag-and-drop reordering so you can arrange documents in the exact sequence needed before merging, and handles PDFs of different page sizes and orientations within the same output file.
Merge PDF examples

FAQ
Is there a limit on how many PDFs I can merge?
There is no strict limit on file count. Processing time depends on total page count and file sizes. Most merges of 10-50 documents complete in seconds.
Will formatting be preserved after merging?
Yes. Each source PDF retains its original formatting, fonts, images, and layout. Pages are combined sequentially without modification.
Can I merge PDFs with different page sizes?
Yes. The merged output preserves each page at its original size. A4 and Letter pages can coexist in the same document.
Can I reorder pages from different documents?
You can reorder entire documents before merging. For page-level reordering across documents, use the Organize PDF tool after merging.
Does merging affect PDF security or passwords?
Password-protected PDFs must be unlocked before merging. The merged output is unprotected by default — use Protect PDF to add security afterward.
