Merge PDF
Combine multiple PDF files into one PDF.
How to merge PDF files
Add two or more PDFs, arrange them in the order you want, confirm the sequence and create the merged document. The final PDF follows the file and page order shown before export.
Check the sequence first
For applications, contracts, reports or multi-part submissions, verify the first page of each document before merging. A correct order is more important than file names, which may not reflect the intended reading sequence.
What merging does not do
Merging combines pages into one document. It does not automatically rewrite page text, normalize page dimensions, fix orientation, compress every page or remove security restrictions.
Different page sizes
A merged PDF can contain portrait, landscape and differently sized pages. This is valid, but the result may look inconsistent when printed. Rotate or resize source documents first if uniformity matters.
Good use cases
Merge PDF is useful for combining invoices, forms, scanned packets, chapters, statements or several files that must be submitted as one document.
Privacy
Supported PDF assembly happens locally in the browser using PDF processing libraries.
Frequently asked questions
Can I merge more than two PDFs?
Yes. Add multiple PDF files and place them in the desired order.
Does merging reduce the quality of pages?
Merging normally combines existing PDF pages rather than intentionally converting them to lower-quality images.
Can merged pages have different sizes?
Yes. The output can contain pages with different dimensions.
Does the original PDF change?
No. A new merged PDF is created.
