Frequently asked questions

Is there a limit on the number of files?+

No fixed limit — it depends only on your device's memory. Dozens of normal PDFs merge in seconds.

Does merging lower the quality?+

No. Pages are copied exactly as they are; nothing is re-rendered or re-compressed.

Are my files uploaded anywhere?+

No. Everything runs inside your browser on your own device, so confidential documents never leave your computer. That also means there's no upload wait.
