How to Merge PDF Files Free Online
Merging PDFs means combining two or more PDF files into a single document, in the order you choose. It is the quick way to turn a set of separate pages — scanned pages, chapters, receipts, forms — into one file that is easy to share, print or store. This guide shows how to merge PDF files for free, in your browser, with no sign-up and no upload: your files never leave your device. Use the free merge PDF tool below to combine your PDFs in seconds.
How to Merge PDF Files — step by step
- Choose your PDF files with “Select PDF files”, or drag them into the file area.
- Check the file list and use the up, down and remove controls to set the order you want.
- Press “Merge PDFs”.
- Download the merged file, named merged.pdf.
Tips
- Check the order first. The merged file follows the order of your list, so use the up and down controls to arrange the files before you press Merge.
- Mixed page sizes are fine. Portrait and landscape pages keep their original sizes in the merged file.
- Add files later if you need to. You can append more PDFs to the list and reorder them before merging.
