Merge PDF

After adding multiple PDFs, drag them into order or sort them by filename in ascending or descending order. Confirm the sequence in the merge-order preview before generating the result, because the final PDF follows the current queue exactly.

The tool writes the pages from each file, in order, into a new PDF and does not overwrite the originals. Page sizes and orientations may differ, but mixed-size documents can look inconsistent when read or printed. Use PDF Page Size first if you need uniform pages.

Not reliably. A PDF that requires an open password or restricts editing may be unreadable. Use Decrypt PDF with a password you know to export a processable file, then merge it.

No. Merging takes place locally in your browser and does not consume a cloud trial or daily quota. Capacity still depends on device memory, the browser, and file complexity, so process large groups of files in smaller batches when necessary.
