How to merge PDF files
- Add the filesDrop them on the box, or click it and pick several files at once. You can add more files later.
- Set the orderMove whole files with Up and Down. Drag single pages to fine tune the order.
- DownloadClick Download merged PDF. Your old files stay as they were.
Files open in the order you choose them. Most file pickers sort by name, so a quick trick is to name the files 1, 2, 3 before you pick them.
Why merge in the browser?
Most merge sites upload your files to their server, join them there and send the result back. That takes time, and your files sit on someone else's computer for a while. Here the joining runs on your own device with pdf-lib, a free open source library. Big files merge fast because nothing has to travel over the internet.
Order by file or by page
The file list is the quick way. Moving a file in the list brings all of its pages together in that place. The page grid is for small changes: drag one page between two others, turn a page that was scanned sideways, or delete a blank page. Undo takes back the last step.
On a phone, hold a page for a moment, then drag it. You can also use the small arrow buttons under each page.
What stays the same after merging
| Part of the file | Kept? | Note |
|---|---|---|
| Text, pictures, page size | Yes | Pages are copied as they are. |
| Text you can select and search | Yes | Nothing is turned into a picture. |
| Page rotation | Yes | Plus any turns you add here. |
| Links on a page | Mostly | Web links work. Links that jump to another page may break. |
| Form fields | Look only | Filled answers show, but the boxes can't be typed in any more. |
| Bookmarks (outline) | No | The side list of chapters is not copied. |
| Password protected files | No | Locked files can't be opened. Remove the password first. |
