Frequently asked questions

Is there a limit on how many PDFs I can merge?

No hard limit — add as many files as your device's memory can handle. Everything is processed locally, so very large batches depend on your browser and RAM.

Will merging keep my original page order?

Yes. Files merge in the order shown in the list. Use the ↑ / ↓ buttons to reorder pages exactly how you want them before combining.

Do my PDFs get uploaded anywhere?

No. Merging happens entirely inside your browser using client-side JavaScript — your files never leave your device or touch a server.
