A PRACTICAL GUIDE

When to use Merge PDF

Join multiple PDFs in your chosen file order for a report, supporting documents or separate notes. Each input’s pages are copied into a new PDF. Use Organise PDF afterward if individual pages need to be moved, rotated or removed.

Join a report and appendix

First: report.pdf — 8 pages
Second: appendix.pdf — 3 pages

Result: 11 pages, report first

Use the file-order arrows before merging. Review the downloaded document because document-level features are not fully preserved.

Frequently asked questions

What are the merge limits?

Choose 2–10 PDFs, up to 20 MB each and 40 MB combined, with up to 100 pages in total. Output is limited to 50 MB.

Can I merge protected or signed PDFs?

Encrypted PDFs and PDFs with interactive forms or signatures are rejected. Use an authorised, unsigned and non-interactive copy.

Will bookmarks and metadata survive?

Not all document-level features or metadata are preserved. This copies pages and is not an archival or sanitisation workflow. Review the result.
