Merge PDF

  2. 2Drag the files (or use the arrows) to put them in the order you want.
  3. 3Click “Merge PDFs” and your combined document downloads instantly.

Frequently asked questions

Are my files uploaded to a server?
No. Every ToucanPDF tool runs entirely inside your browser using your device’s own processing power. Your file is read into memory, worked on locally, and handed back as a download — it never travels to us or anyone else. You can even go offline after the page loads and the tool still works.
How many PDFs can I merge at once?
As many as you like. Because the work happens on your own device, the practical limit is your computer’s memory rather than an upload cap — hundreds of pages are no problem.
Will the pages keep their quality?
Yes. Merging copies each page as-is, so text stays sharp and selectable and images are untouched. Nothing is re-compressed or flattened.
