How to Merge PDF Files Into One (Free and Private)
Updated 18 October 2026 · 3 min read
Combine several PDFs into a single file in the right order — on phone or computer, without uploading your documents.
Why merge PDFs
Many applications accept only one file: a job application with resume plus certificates, a visa form with supporting documents, or a project report made of separate chapters.
Steps to merge
Use the Merge PDF tool:
- Add all the PDF files you want to combine.
- Drag them into the correct order.
- Click Merge and download the single PDF.
Keep the final file small
Merged files can get large. Use the Merge and Compress workflow to combine and shrink in one step, which is useful when the portal has a size limit.
