What is the PDF Merger?

Put several PDFs together into a single file — invoices, scanned pages, chapters. Everything happens in your browser, so your documents are never uploaded.

How it works

How to use the PDF Merger

3 simple steps. No experience needed.

What can you use it for?

  • Combine scanned pages into one document.
  • Send several attachments as one file.
  • Join chapters or reports into a single PDF.

Putting files in order

Files are merged top to bottom in the order shown. Use the arrows to move a file up or down before merging — for example to put a cover letter before a CV, or chapters in sequence.

What stays the same

Pages are copied as they are, so text stays selectable and images keep their quality. Nothing is re-compressed or watermarked.

FAQ

Frequently asked questions

Is there a file size limit?

No fixed limit — it depends on your device's memory. Hundreds of pages are usually fine.

Can I merge password-protected PDFs?

Remove the password first in your PDF reader, then merge.

Are my files uploaded?

No. The merging happens entirely in your browser.
