Frequently Asked Questions
Is there a limit on the number of files?
No hard limit — merging happens in your browser's memory, so very large batches may be slow on low-memory devices.
Are my PDFs uploaded anywhere?
No. The merge runs entirely with JavaScript in your browser; your files never leave your device.
Will the merged PDF have a watermark?
No watermark is added. The output contains only your original pages.
