How to use Merge PDFs
Combine several PDFs into one downloadable document by copying their pages in the order shown in the file list.
- Choose 2–10 PDF files, each up to 25 MB.
- Review the displayed file order before merging; reset and reselect if the order is not what you intended.
- Merge, download the combined PDF, and check its page sequence.
Worked example
Place a two-page cover document before a three-page report to create one five-page PDF with the cover first.
Limits and things to check
Encrypted or damaged documents can fail. Document-level features such as signatures, bookmarks, and interactive forms may not survive page copying as expected. Large files require browser memory; retain the originals.
Does merging compress my PDFs?
No. Merging copies pages into one file and does not aim to reduce their size. Use PDF compression separately if image-based output is acceptable.
