Merge PDF Online: Combine Multiple PDFs Into One File
Joining scanned pages, invoices, reports, or chapters into a single document usually means opening desktop software or paying for a subscription. ConvertBrio's merge tool does it directly in your browser — upload multiple PDFs, arrange them in order, and download one combined file in seconds.
How to Merge PDF Files
Upload two or more PDF files at once, arrange them in the order you want them to appear in the final document, and click Convert. ConvertBrio combines every page from each file, in sequence, into a single downloadable PDF.
Common Reasons to Merge PDFs
People merge PDFs to combine scanned pages into one document, assemble a multi-part report or contract, bundle invoices for a single submission, or join chapters of a book or manual. It's also useful for combining separately-scanned double-sided pages into a properly ordered document.
File Order and Limits
The order you upload or arrange files in determines the order they appear in the merged PDF, so double-check the sequence before converting. Free merges work with files up to 25 MB each; paid plans raise that limit for larger documents.
