Frequently Asked Questions (FAQ)
Are my PDF files safe?
Absolutely. All processing and merging of PDF files happen locally inside your web browser (client-side). We do not upload, store, or transmit any of your files to our servers.
Is there a file size or quantity limit?
There are no strict limits imposed by our tool, but performance depends entirely on your computer's available RAM. Merging dozens of extremely large PDF files simultaneously might cause your browser to slow down or run out of memory.
In what order are the pages merged?
The files are appended in the exact order they appear on your screen (from top to bottom). You can easily rearrange them using the Up and Down arrow buttons next to each file before you click the Merge button.
