Good to know

Are my PDF files uploaded anywhere?

No. The merge runs entirely inside your browser, so your documents never leave your device.

How many PDFs can I merge?

There is no fixed limit. Very large files depend on your device's available memory, since all the work happens locally.

Can I change the order of the files?

Yes. Drag a row to a new position, or use the up and down arrows next to each file before merging.

Why does a file fail to merge?

Password-protected or damaged PDFs can't be read. Remove the protection or re-save the file, then try again.
