Merge PDF
Combine multiple PDF files into one document. Free online PDF merger with drag-and-drop reordering.
About This Tool
Merge PDF joins two or more PDF files into one, in the order you put them.
Add the files, then drag them or use the arrows to set the order. The pages are copied as they are, without compressing anything again, and links inside each file keep working. The files' own bookmarks are not carried over; instead the merged file can get one bookmark per file, named after it. Form fields stay fillable, and where two files have a field of the same name, as two filled copies of one form do, each keeps its own answer.
All merging happens locally in your browser, ensuring complete privacy for your sensitive documents.
