Frequently asked questions
How do I merge PDF files for free?
Add your PDFs, arrange them in the order you want and press “Merge PDF”. The tool is free, needs no account and adds no watermark.
Are my PDFs uploaded to a server?
No. Merging runs entirely in your browser. Your documents never leave your device, which makes the tool safe for private files.
Will the merged PDF keep the original page sizes?
Yes. Every page keeps its original size and rotation, even if your files use different page sizes.
Is there a limit on how many files I can combine?
There is no fixed limit. Each file can be up to 200 MB, but very large batches depend on the memory of your device.
Can I merge password-protected PDFs?
Not directly. Remove the password in the app you used to protect the file, then add it again.
Combine PDF files quickly and privately
Need to combine several documents into one? This free merge PDF tool lets you join PDF files in seconds, straight from your browser. Add as many files as you like, drag them into the right order and download a single, tidy PDF. The size and rotation of every page are preserved, so the result looks exactly like the originals.
Unlike many online services, this tool never uploads your files. The work happens on your own device using your browser’s processing power, which is faster for everyday documents and much safer for contracts, invoices, ID scans and other private papers. There is nothing to install, no account to create and no watermark on the result. Use it to bundle scanned pages into one report, to gather invoices before sending them to your accountant, or to assemble an application from several separate files. When you are done, you can reorder, split or rotate pages with our other free PDF tools.
