How to Merge PDF Files Online
Merging PDFs creates one document from several separate files. It is useful for combining application documents, scanned pages, reports, invoices, certificates, or coursework in a clear order.
Prepare the files first
Open each PDF and confirm that its pages are complete and correctly oriented. Rename files clearly if that helps you recognize their intended order.
Arrange the document order
Add at least two PDF files, then use the movement controls to place them in the sequence you want. The first listed file becomes the beginning of the merged PDF.
Merge and verify
Create the combined PDF and open the downloaded result. Check the first and last page of every section, especially when the document will be submitted to an employer, school, client, or official portal.
Password-protected files may need to be unlocked by their owner before they can be processed. If the merged document is too large, use the PDF Compressor after checking that all pages are present.
