Download merged PDFAbout merging PDFs
Select at least two PDFs. Every page is copied in order, preserving its size and rotation. Encrypted or password-protected PDFs must be unlocked before adding them.
This tool merges pages using the open-source pdf-lib library. Document-level features such as bookmarks, digital signatures, and interactive forms are not preserved as working features.
Example: combine a report and its appendix
Place your report first and the appendix second to keep that reading order in the merged PDF. Every page from both files is included. To use only selected pages, split the source PDF first.
