How to reorder pages before merging
If you need to rearrange individual pages — not just files — use the PDF Organizer instead. It shows thumbnail previews of every page and lets you drag them into any order before exporting.
Is it safe to merge PDFs online?
With TARUMAK Tools, yes. All processing happens locally in your browser using JavaScript. Your PDF files are never sent to our servers, never stored, and never seen by anyone else. You can even use it offline after the page has loaded.
When merging does not work
If a PDF is password protected, you need to unlock it first. Use the PDF Unlock Tool to remove the password, then merge.

Is there a file size limit?
No artificial limits. The practical limit depends on your browser and available RAM. Most modern computers can handle PDFs up to a few hundred MB without issues.
Can I merge more than two PDFs?
Yes — drag in as many files as you need. There is no limit on the number of PDFs you can combine.
