Think of file order as reading order
Joining PDF files is useful when separate documents form one continuous record: several scan batches, a report and its appendix, sequential notes, or documents collected from different sources. The main decision is the sequence. Start with the file that introduces the material, then arrange the remaining files in the order someone should read them.
The workspace shows each selected PDF as its own item, so you can check names and page totals before combining them. This is especially helpful when file names are similar or several documents were created on different days.
How to join PDF files into one
- Add the complete PDF files. Select the documents that belong in the final record. If a PDF contains pages that should be removed or rotated, fix that source separately first because this tool joins whole files rather than editing individual pages.
- Set the right sequence. Move the files into a deliberate reading order. For scan batches, use page ranges or batch names to keep the beginning, continuation, and ending in the right positions.
- Use a recognisable filename. Include the project, case, date, or record type in the output name. This helps distinguish the joined file from the individual sources and from later corrected versions.
- Check the hand-offs. Open the downloaded PDF and review where each source file ends and the next begins. Those transitions often reveal a missing batch, repeated scan, unexpected blank page, or a section placed in the wrong order.
Joining files is not the same as editing pages
The combined PDF follows the order of the files in the queue, while the pages inside each source stay in their existing order. The merge does not automatically sort pages by printed page number, remove blanks, rotate a sideways scan, or create a table of contents.
Scans and protected documents need extra care
Joining image-only scans does not make their text searchable; OCR is a separate step. Password-protected or damaged PDFs may fail to load. If the documents contain digital signatures, forms, bookmarks, or other special features, inspect the finished file and retain the originals when those features are important.
