Quick answer: To merge PDFs, add the files to a merge tool, drag them into order and save one combined PDF. To split a PDF, choose the pages to extract or remove, or split every N pages, then save. To reorder pages, drag page thumbnails into place. The Merge PDF and Split PDF tools here do all of this in your browser, so the files are never uploaded.
How to merge PDF files
- Open Merge PDF and add two or more files, or drag them in.
- Put the files in order by dragging them.
- Choose page ranges if you only need part of a file, for example pages 1-3 of a contract and page 5 of an appendix.
- Merge and save the combined PDF, then check the page count.
How to split a PDF
| You want to… | Split option | Example |
|---|---|---|
| Keep only some pages | Extract pages | Extract 2, 5-7 from a 20-page file |
| Delete some pages | Remove pages | Remove 1 and 20 (cover and blank page) |
| Break a file into equal parts | Split every N pages | A 60-page scan into 6 files of 10 pages |
| One file per page | Split every 1 page | A multi-page invoice batch into single invoices |
Writing page ranges
| Range | Means |
|---|---|
| 3 | Page 3 only |
| 1-5 | Pages 1 to 5 |
| 1-3, 7, 10-12 | Pages 1, 2, 3, 7, 10, 11 and 12 |
| 8- | Page 8 to the end, where supported |
Page numbers are the position in the file, which can differ from numbers printed on the pages. Check the thumbnail view before splitting.
Reordering and rotating pages
Scanned documents often arrive out of order or sideways. Drag thumbnails into the right sequence, then use Rotate PDF for pages that are upside down or landscape. Rotation is saved in the file, so it opens correctly for everyone.
Common workflows
- Job application: merge cover letter, CV and certificates into one PDF, then compress it for the upload limit.
- Signed contract: extract the signature page, sign it, and merge it back in place.
- Expense claim: merge receipts into one file in date order.
- Scanned book or report: remove blank pages, reorder, add page numbers.
Troubleshooting
| Problem | Likely cause | Fix |
|---|---|---|
| A file will not open | Password protected | Open it with the password in your PDF reader and save an unprotected copy you are entitled to make |
| Form fields vanish after merging | Some merges flatten or drop fields | Fill and flatten forms first with Fill PDF Form |
| Merged file is huge | Large scanned pages | Compress after merging |
| Pages look sideways | Scan orientation | Rotate PDF, then save |
