How to Merge PDF Files into One Document
Combine several PDFs in the order you want, and tidy the result afterwards.
Applications, reports and expense claims often need several documents sent as a single file. Merge PDF joins them in your browser, so the documents are not uploaded.
Quick steps
- Open Merge PDF and add two or more PDF files.
- Drag the files into the order you want.
- Press merge and download the combined PDF.
Plan the order first
Give your files names that sort correctly before adding them — for example 01-application.pdf, 02-id-proof.pdf, 03-marksheet.pdf. If a form specifies an order for enclosures, follow it exactly.
Clean up after merging
- Remove blank or duplicate pages with Delete PDF Pages.
- Move single pages around with Organize PDF.
- Turn sideways scans upright with Rotate PDF.
- Add page numbers with Add Page Numbers so reviewers can refer to pages.
- Reduce the final size with Compress PDF.
Mixing images and PDFs
Convert photos with JPG to PDF first, then merge the resulting PDF with your other documents.
Frequently asked questions
Can I merge a password-protected PDF?
Remove the password first with Unlock PDF. You need to know the password.
Does merging reduce quality?
No. Pages are copied as they are; nothing is recompressed.
Are bookmarks and form fields kept?
Page content is preserved. Document-level extras such as bookmarks may not carry over, and form fields with the same name in two files can conflict — flatten filled forms before merging.
