How to merge PDF files
Add two or more local PDFs, place them in reading order, choose the pages you need, and download one merged PDF. The Merge PDF tool also lets you add flat file-level bookmarks and preview the pages before you save the result. The files stay local in your browser and are not uploaded.
Put the PDFs in the order you need
Open Merge PDF, add two or more local PDFs, and drag them into order. If PDF A is above PDF B, the pages from PDF A come first in the merged file. Page size and rotation are preserved, so the source pages keep those settings.
Keep only the pages you need
Choose a page range for each source file before creating the merged PDF. A long report can contribute selected pages while its cover sheet or appendix stays out. Add flat file-level bookmarks, preview the pages, and check the order before downloading the new file.
Check files that are flagged
Merge PDF flags encrypted, signed, malformed, and unsupported files. It does not silently remove encryption or rasterize unsupported content. Remove or replace a flagged file before creating the merged PDF.
Examples of PDF merging
- A project folder contains a cover PDF and several section PDFs. Put them in reading order and download one file.
- A long report includes pages you need and an appendix you do not. Set a page range for the report before combining it with the appendix.
- A handoff package contains several PDFs. Add file-level bookmarks, preview the pages, and check the structure before downloading.
Use PDF Tools for other PDF jobs
Choose PDF Merge Tools when you need two or more PDFs in one file. For compressing, converting, editing, splitting, redacting, repairing, or extracting text, start with PDF Tools and choose the matching category.
