How to merge PDF files online
PakPro’s free Merge PDF tool joins several PDF files into one PDF, in the order you choose. Everything happens inside your browser — files are never uploaded.
- Add your PDFs — drag and drop, or click to browse.
- Arrange the order — drag files or use Up/Dn buttons.
- Name your file (optional) and click Merge PDFs.
- Your merged PDF downloads automatically.
Worked example. Cover-Letter.pdf (1 page), CV.pdf (2 pages), Portfolio.pdf (4 pages). Add all three, drag the cover letter to position 1, click Merge PDFs — one 7-page PDF.
