Any modern browser, on desktop, tablet or phone. Nothing to install.
Merge PDF — Frequently asked questions
Is merging PDFs online safe?
Yes. Files are processed in isolated memory and deleted immediately. Free users' files are never persisted.
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.
Do I need to sign up?
No. You can merge up to three files per day for free without an account.
