Common reasons to merge PDFs

- Business reports: assembling chapters written separately
- Finance and accounting: grouping receipts, invoices, and bank statements
- Legal documents: packaging agreements, exhibits, and signatures together

Tips for organizing your merged document
Order matters before you click merge. Think about how a reader will move through the combined document: title page first, then main content, then supporting appendices. If any PDFs have mixed portrait and landscape orientations, most merge tools preserve them.
Need the opposite? Split a PDF
If you received a large combined PDF and need to pull out specific pages — like extracting a single invoice from a multi-document file — use a PDF splitter instead.

Frequently Asked Questions
Is there a file size limit for merging PDFs?
LoudHive processes PDFs in your browser, so limits depend on your device memory. Most modern computers handle PDFs up to several hundred MB without issues.
Will the merged PDF have watermarks?
No — LoudHive never adds watermarks. You get a clean merged PDF.
Can I merge password-protected PDFs?
The PDFs must be unlocked first. If you know the password, open the PDF and save it as a new file to remove the protection, then merge.
Does the order of files matter?
Yes — files are merged in the order you upload or arrange them. You can drag to reorder before clicking Merge.
