Merge PDF

Nothing is uploaded: the file is opened and processed inside your browser and never leaves your device. Close the tab and it is gone.

Yes. Add a JPG, PNG or other image, or a .docx, .xlsx or .pptx file, and it is converted to PDF in your browser as it arrives, then merged like any other PDF - nothing is uploaded. An image goes on an A4 page of its own; an Office file is laid out by our own converter, so a font the document uses but your device lacks is replaced with a similar one.

Yes - drag the file cards into the order you want, or sort them by name, page count or size. The merged PDF follows the list from top to bottom.

The original outlines do not survive - merging builds a new document. What you can have instead is one bookmark per merged file, named after it, so a long stack stays navigable. The original page labels can be preserved, though, instead of renumbering everything 1..N, and a separator page or a table of contents can be added too.

For two-sided scans made with a one-sided scanner: one file holds the odd pages, the other the even ones, and alternate mix interleaves them page by page into the right reading order.

Yes, once it is unlocked in the list: a locked file shows a lock icon, you click it and type the password, and from then on it merges like any other. Without the password it stays out of the run, and the button says so.

With a free account, two files per run; with Pro, as many as you like in one go. The work happens on your own machine either way, so the limit is about the plan, not about your computer.
