Merge PDF
Combine multiple PDF files into a single document. Upload your files in the order you want them merged.
How to use the Merge PDF
- Select or drop the PDF files you want to combine.
- Make sure they're in the order you want. Files are merged in the order you select them.
- Click Run and download the single merged PDF.
How the Merge PDF works
The merger opens each PDF and copies all of its pages, in order, into a new document: every page from the first file, then every page from the second, and so on. Pages are copied rather than re-rendered, so text stays selectable and images keep their quality.
Uploads can be up to 100 MB in total. Password-protected files must be unlocked first with PDF Unlock. To pick only certain pages from a file before merging, use Extract PDF Pages, and to fix the order afterwards, use Reorder PDF Pages.
