How it works
- Open the PDF merger. Go to the Formatly PDF Merger page. The tool is free and requires no account.
- Upload multiple PDFs. Select two or more PDF files (up to five) and drop them into the upload container.
- Merge the documents. Confirm that the selected target action is 'Merge PDFs' and click Convert.
- Download the combined PDF. Click the Download button to save the merged PDF file to your computer.
When merging PDFs makes sense
Most people merge PDFs to assemble a single document out of several: a job application with a resume, cover letter, and references; a bank reconciliation with multiple statements; a project brief built from team contributions. Sending one combined file is easier for the recipient and keeps related pages in the right order.
Merging is also a cleanup move. If you have scanned pages, downloaded chapters, or printed documents scattered across folders, combining them into one PDF gives you a single, searchable archive. The tool preserves each source page exactly as it is — no recompression, no quality loss — and simply concatenates the documents in the order you drop them in.
FAQ
How many PDFs can I merge at once? You can upload and merge up to five PDF files at a time. Each file can be up to 20 MB.
In what order are the PDFs combined? The files are merged in the order they are selected and uploaded. We combine them top-to-bottom sequentially.
Can I merge password-protected PDFs? No. If any of the uploaded PDFs are encrypted or password-protected, the merge task will fail. Please unlock them before merging.
Is there a limit on how many PDFs I can merge? You can combine up to five PDFs in one merge, and each file can be up to 20 MB. That covers applications, statement bundles, and most day-to-day documents; everything is deleted from our servers an hour after conversion.
