Examples describe expected workflows unless a dated test is explicitly identified. Check the downloaded result against your own document before sharing it.

What merging a PDF means

Merging combines multiple PDF documents into one file while preserving the page order you choose. The result is a single PDF that can be shared, printed, or archived as one document.

Merging is useful for contracts with exhibits, scanned chapters, receipts, presentations, and any collection of pages that belong together.

Steps to merge PDFs

Open the Merge PDF tool and drag the PDF files into the upload area, or click to browse.

Review the file list and remove any file you do not want included. Files are processed in the order shown.

Click Merge PDF. Your browser combines the pages locally and shows a preview.

Download the merged PDF. Keep the originals until you have checked the downloaded result.

Tips for clean merged documents

Combine documents with similar page sizes so pages do not shift when viewed side by side.

Check the final page count before distributing the file.

Use Split PDF first if you need to remove unwanted pages before merging.

Plan the packet before combining files

For a handover packet with a two-page cover, a six-page report, and three receipt pages, the expected result is 11 pages. Add the cover first, then the report, then the receipts. These are illustrative counts, not a benchmark for your files.

Merge includes every page of each source. If only pages 2-4 of the report belong in the packet, extract that range first; the revised packet should contain eight pages. Merge does not sort documents by the dates printed inside them or standardize page dimensions.

Check the joins, not only the first page

Reopen the download and inspect pages on both sides of every file boundary: in the 11-page example, pages 2/3 and 8/9. Confirm the last receipt is present and that landscape pages remain readable.

Try any bookmarks, links, forms, and signatures the recipient relies on. Copying pages into a new document is not a guarantee that document-level features survive. Keep the separate originals when they are the authoritative records.
