Frequently asked questions
Can I reorder the pages before merging?
Yes — after you add your PDFs, drag them (or use the up/down arrows) into the order you want. They're combined top to bottom in that order.
Is there a limit to how many PDFs I can merge?
No hard limit on the number of files — the practical limit is your browser's memory for very large combined documents (hundreds of megabytes).
Will merging keep bookmarks and links?
Page content, images and text are preserved exactly. Internal links and bookmarks from the original files are not currently carried over into the merged document.
Is Merge PDF free to use?
Yes — Merge PDF is completely free with no limits, no watermarks and no sign-up. It runs in your browser, so there is nothing to pay for.
Are my files uploaded or stored anywhere?
No. This tool does all its work locally in your browser using your own device's power. Your files never leave your device and we never see them.
Do I need to install anything or create an account?
No installation and no account needed. Merge PDF works on any modern browser — Windows, Mac, Linux, Android and iPhone.
How do I use Merge PDF?
Open the tool, add your file (or paste your content), adjust any options, then press “Merge PDF”. Your result is ready to download in seconds.
