How to use this tool
- Choose the PDFs you have permission to modify.
- Reorder the source-file list to set the document sequence.
- Merge and check every page, then apply a separate target-size operation only if needed.
What to check before downloading
Do not assume document-level features or digital signatures survive merging. Password-protected sources need an authorized compatible copy.
Common questions
Does merging guarantee a smaller file?
No. It combines pages. The resulting file may exceed a portal’s ceiling, so check its actual size before deciding whether a separate compression step is appropriate.
Do I need to upload files to a server?
No. This version processes selected files in your browser. Website assets still load from the hosting service. See our privacy information and file limits.
