A step-by-step guide to combining multiple PDFs into one document — free, without watermarks, and without uploading to a random server.
The fastest way
Use our free PDF Merger. Drag your PDFs in, reorder them, download the combined file. Everything happens in your browser.
If you need a desktop option
On Mac, Preview can merge PDFs. On Windows, PDF24 Creator is free and offline. On Linux, pdfunite from poppler-utils.
How to reorder pages
Most mergers let you drag and drop the file order before merging. Once merged, reordering requires a PDF editor.
How to also remove pages
Merge first, then use our PDF Cutter to extract only the pages you want.
