How to Merge PDF Files
Combining multiple PDFs into one document is one of the most common PDF tasks — assembling a report from separate sections, joining scanned pages, or building a single packet from documents that arrived separately.
Using AllPDFMagic Merge
- Go to AllPDFMagic Merge and upload the PDFs you want to combine.
- Drag to reorder them into the sequence you want in the final document.
- Click Merge and download the combined PDF.
The tool works entirely in the browser, requires no signup, and handles files up to the size limit of your plan.
A Note on Bookmarks and Outlines
If your source PDFs contain bookmarks (the navigation outline some PDF readers show in a side panel), whether they carry over into the merged file depends on how each source PDF was structured — this isn't a guaranteed, dedicated feature of the merge process. If a clean navigable outline in the final document matters for your use case (a long technical manual, a multi-chapter report), it's worth checking the merged output afterward and adding bookmarks manually in a PDF editor if the originals didn't carry through cleanly.

Frequently Asked Questions
It depends on how the source PDFs were structured — bookmark/outline preservation isn't a dedicated, guaranteed feature of the merge process. Check the merged file afterward and add bookmarks manually if needed.
Free tier supports merging PDFs up to the plan's file-size limit; higher plans support larger files and batch processing. Check current plans for exact limits.
You'll need to unlock a password-protected PDF first using the Unlock tool before it can be merged, since the content needs to be readable to combine it.
No — pages are combined at their original resolution and quality. Nothing is re-compressed or re-encoded during a merge.
