Need to send one tidy document instead of a pile of attachments? Modocca's free PDF merger combines several PDF files into a single PDF in the order you choose. Drop your files into the box above, drag them into the right sequence, and click Merge PDFs.
Merging works for invoices, scanned receipts, reports, contracts with appendices, or chapters of a longer document. Every page keeps its original layout, fonts and images, because pages are copied as they are rather than converted. There is nothing to install, and it works the same on Windows, Mac, Chromebook and mobile browsers.
Editing is free with no signup. To download, create a free account — your first 2 downloads are on us. Your files are stored privately, only you can open them, and they are deleted automatically.
Want to tidy the result first? After merging you can remove pages you don't need, rotate sideways scans, or add text and a signature with our editor.
Before sharing the combined file, check that the first page introduces the document and that any supporting attachments follow in a sensible order. Remove duplicate copies before merging, and review the final page count. If the recipient sets an upload size limit, use Compress PDF on the merged result before sending it.
Frequently asked questions
Is merging PDFs really free?
Yes. You can merge without an account. Downloading needs a free account, which includes 2 free downloads. After that a 24-Hour Pass costs £2.99.
How many PDFs can I merge at once?
You can add as many files as you like, as long as each file stays within your plan's size limit (20MB without an account, 50MB on a free account).
Can I change the order of the files?
Yes. Drag the files in the list into any order before you merge.
Will merging reduce the quality?
No. Pages are copied into the new file unchanged, so text and images look exactly as before.
