How to use it

  1. Choose at least two supported PDF files.
  2. Arrange the file cards with drag or move buttons.
  3. Merge and download after checking the order.

Check file order before merging

Input
File A has 2 pages; file B has 1 page. Place B before A.
Result
3 pages: B1, A1, A2

Move whole-file cards with the arrow buttons on a phone or by dragging where supported. Use the PDF page organizer when individual pages need reordering. Review the exported file; merging is not a redaction or a guarantee that signatures and forms are preserved.

Useful situations

  • Combine a cover sheet and assignment.
  • Join several small reports into one file.

Limits and supported formats

Local processing; at most 20 MiB combined and 60 PDF pages. Password-protected, damaged or unsupported PDFs are rejected. Editing creates a new file and can invalidate signatures or omit interactive features; preserve the original. This is not redaction or form editing.

Privacy

We do not store tool content or results. Optional usage events do not include files, filenames, text, passwords or QR contents. Reset when finished and save any output you need on your own device.

Questions about this tool

Can I arrange individual pages while merging?

Merge follows each file’s page order. Use PDF Page Organizer on the combined output when individual pages need reordering or rotation.
