How to Merge PDF Files Into One (Free, on Any Device)
Quick answer
Open a browser-based PDF merger, add your PDF files, drag them into the order you want and click Merge. You get one PDF containing every page of every file. With a tool that runs locally, your documents are never uploaded.
Steps
- Open Merge PDF.
- Click “Choose PDF files” and select all the files (hold Ctrl or Cmd to pick several).
- Drag the file cards into the right order – on a phone, use the arrow buttons.
- Click “Merge PDFs” and then “Download”.
Need to fine-tune the result?
- Pages in the wrong order or sideways? Use Reorder & Rotate PDF on the merged file.
- File too large to email? Run it through Compress PDF.
- Only need some pages from each file? Extract them first, then merge.
Why merge in the browser?
Many online mergers upload your files to a server. Browser-based tools use JavaScript on your device instead, which is faster for large files on slow connections and means sensitive documents such as contracts or IDs stay with you.
Password-protected PDFs cannot be merged until they are unlocked with their password in a PDF reader.
