Drop two or more PDF files into the box above. They open together in the editor as one continuous set of page thumbnails, in the order you dropped them.
Use the ↑ and ↓ buttons on any thumbnail to move its page earlier or later, if you need a different order than the one you dropped them in.
Click Export PDF. The combined document downloads as a new PDF.
There is no fixed cap on the number of PDFs you can merge. Because merging happens in your browser, the practical limit is your device's memory: dozens of typical documents combine without trouble, while very large files may be slower on older hardware.

Yes. Once your files are combined, every page appears as its own thumbnail with ↑ and ↓ buttons in the same editor, so you can reorder, rotate, or delete individual pages before exporting. There's no separate step; it happens right where you merged.
Yes. The merge tool runs in any modern browser, including Safari on iOS and Chrome on Android. Select PDFs from your phone's file picker, merge them, and the combined document saves to your downloads.
