Combine PDF documents in the right order

Before merging, arrange the selected documents in the order they should appear in the final file. Open the merged PDF after downloading and check page order, page orientation, embedded fonts and any form fields that matter to your workflow.

Why might a PDF fail to merge?

A damaged, encrypted or unsupported PDF can prevent a browser library from reading the file. Try opening and resaving the source document in a trusted PDF application, then select the repaired copy. Keep your original documents until the merged file has been checked.
