How it works

1

Collect the files

Select every PDF file you want in the final document, in one go or a few batches.

2

Check the sequence

File names rarely sort the way you want, so drag each card into its true position.

3

Combine

One click writes all the files into a single PDF file on your device.

Handling many separate PDF files

Scanners and mail clients love producing one PDF file per page: scan_0001.pdf, scan_0002.pdf and so on. Adding all of them at once and merging turns that mess into a single readable document you can archive or email.

If two files were scanned in the wrong order, drag them into place before merging instead of re-scanning.

Mixing page sizes and orientations

A4 pages, US Letter pages and landscape spreadsheets can all live in the same merged file. Each page keeps its own dimensions, so nothing is stretched or cropped to force a uniform size.

Frequently Asked Questions

How do I merge PDF files that are named out of order?+

Add them all, then drag the cards. The tool honours the visual order you set, not the alphabetical file name order.

Can I merge files from different folders?+

Yes. Add one folder's files, then click Add more and pick from a second location — everything joins the same queue.

Does the file name of the merged PDF matter?+

Only for you. The download is named automatically, and you can rename it afterwards without affecting the contents.

Can I remove one file after adding it?+

Yes, each card has a remove button, so you can drop a duplicate scan without starting over.
