How to Use
- Add the PDF files you want to combine.
- Check their order. To use a different order, clear the list and add the files again in that order.
- Run Merge PDFs, download the output and verify the page sequence.
Keep Attachments Together
Sharing a main document and its attachments as one PDF helps recipients follow the sequence. Merging increases the page count; it is a different task from reducing file size.
Check the Merged Output
Review the first and last pages, orientations and attachment order. Do not assume that forms, bookmarks or digital signatures are preserved unchanged; keep signed originals separately.
Frequently Asked Questions
What determines page order?
The first file’s pages come first, followed by the second file’s pages, and so on.
Can I merge password-protected PDFs?
Support for encrypted PDFs is not guaranteed in this browser workflow. Use an unlocked copy of a document you are authorized to process.
