Merge PDF files into one

Join several PDFs into a single document, in the order you choose. Your files never leave your device.

Open the board Free. No sign-up. Your files stay on your device.

How to do it

  1. Drop all the PDFs you want to join onto the board.
  2. Select one PDF card and open the Merge tab.
  3. Tick the files to include and move them up or down to set the order.
  4. Press merge and download the combined PDF.

Good to know

Merging keeps the pages exactly as they are, so text stays selectable. You can also use the page tools to keep only the pages you need before or after merging. Password-protected PDFs need to be unlocked first.

When to use it

Use it to put an application together from separate parts, such as a cover letter, a CV and certificates, or to join chapters, invoices or scanned pages into one document you can send in a single attachment.

Tips for better results

  • Check the order before you merge. Moving a file after the fact means doing the merge again.
  • Name your files with numbers first (01, 02, 03). The list is then easy to line up.
  • If one PDF has pages you do not want, remove them first so the final file stays tidy.
  • A merged file can get large. Compress it afterwards if an upload limit applies.

Questions

How many PDFs can I merge?

There is no set limit. The practical limit is your device memory, so very large files may need to be merged in smaller groups.

Does merging reduce quality?

No. Pages are copied as they are, without being redrawn.

Can I merge images with PDFs?

Yes, in two steps: turn the images into a PDF with the image to PDF tool, then merge that PDF with the others.
