FAQ

Common questions

How many PDFs can I merge at once?

There is no hard limit. You can merge as many PDFs as your device memory allows — typically dozens of files without any issue.

Are my files uploaded anywhere?

No. All processing happens inside your browser using WebAssembly. Your PDFs never leave your device.

Can I reorder pages before merging?

Yes. Drag and drop the uploaded files to set the order before combining them.

Is the merge tool really free?

Yes — the merge tool is free for up to 5 uses per day. Unlimited usage is available on the Pro plan.
