Class notes split across files, separate invoices, documents scanned one page at a time… sooner or later you need to hand everything over as one single PDF. The old answer was installing heavyweight software; the new one is the ToolBox PDF merger — it does the whole job in your browser, in seconds.
What makes it different?
- No upload: most PDF sites send your files to their servers. Here, processing happens entirely inside your browser — confidential documents (contracts, IDs, medical records) never leave your device.
- No limits: unlimited files, unlimited size, unlimited uses — genuinely free.
- No watermark: a clean, standard output with no extra pages or stamps.
The features you actually need
- Any order: drag files (or use the arrow buttons) to arrange them.
- Delete pages: open Pages to preview every page as a thumbnail and remove any of them with one click.
- Rotate: fix landscape or upside-down scans on the spot.
- Page ranges: type 1-5,8 to keep just those pages.
- Remove pages from one PDF: load a single file and use it as a page remover.
How to merge PDFs step by step
- Pick your PDF files or drop them onto the page.
- Arrange the order and, if needed, edit the pages.
- Name your output file and hit Merge & Download — done!
