Merge PDF — Frequently asked questions
Is merging PDFs online safe?
Yes. Files are transferred over HTTPS, stored encrypted at rest and auto-deleted after 24 hours on Free (30 days on Pro).
Is there a page limit?
No page limit. The only cap is the per-file size — 10 MB on Free, 50 MB on Pro.
Can I reorder pages inside a PDF?
This tool concatenates whole files. To reorder pages inside a single PDF, use Split PDF to extract ranges first.
How long do you keep my file?
24 hours in your history on the Free plan, 30 days on Pro. After that it's deleted automatically.
Is Merge PDF free to use?
Yes. The Free plan lets you run Merge PDF twice a day on files up to 10 MB, no card required. Pro removes the daily limit and raises the size cap to 50 MB.
Does Merge PDF work on Mac, Windows, iPhone and Android?
Yes. Merge PDF runs in any modern browser, so it works the same on macOS, Windows, Linux, ChromeOS, iOS and Android — no app to install.
What's the maximum file size?
10 MB per file on the Free plan, 50 MB on Pro and 200 MB on Business. Larger files should be compressed first with the Compress PDF tool.
