Merge PDF files
Combine several PDFs into one document, in the order you want.
Drag to reorder, or use the arrows.
Your files never leave your device. Everything happens in this browser tab. Nothing is uploaded, and closing the tab erases it.
How it works
- Drop your PDF files here, or choose them from your device.
- Drag them, or use the arrows, to set the order.
- Press Merge PDF and the combined file downloads.
Questions
Are my files uploaded anywhere?
No. The merging happens inside your browser, on your device. You can even switch off your internet once the page has loaded and it still works.
Is there a limit on files or size?
Dozo sets no limit. The only limit is your device’s memory: very large files can be slow on an older phone.
Can I change the order of pages, not just files?
Merge first, then open the result in Organize PDF to move, rotate or delete individual pages.
Does it keep links and bookmarks?
Page content, links and form fields are kept. The table of contents (bookmarks) of each file is not carried over.
